Subject and Predicate in English Grammar: Rules and Examples

Every complete English sentence communicates something about a person, place, thing, or idea. It may tell us what someone does, describe a situation, express an opinion, ask a question, or give an instruction. To understand how a sentence communicates its meaning, learners must understand two important grammatical elements: the subject and the predicate.

Consider this sentence:

The young woman prepared for her job interview.

Who or what is the sentence about? It is about the young woman. What does the sentence say about her? It says that she prepared for her job interview.

The part that identifies who or what the sentence is about is called the subject. The part that tells us something about the subject is called the predicate. Together, these two elements form the basic structure of most English sentences.

Understanding subject and predicate is important because they help learners construct complete sentences, recognise grammatical relationships, identify sentence errors, and improve their writing. These skills are useful in school assignments, examinations, professional emails, everyday conversations, and job interviews.

For example, a job applicant who understands sentence structure can distinguish between an incomplete expression such as Because I have relevant experience and a complete sentence such as I believe I am suitable for this position because I have relevant experience.

In this lesson, you will learn what subjects and predicates mean, how to identify them, the different forms they take, how they work together, and the rules that govern their use. You will also study common errors, practical examples, and exercises with answers.

By the end, you should be able to identify the subject and predicate in different types of sentences and use them correctly when speaking and writing English.

1. What Is a Subject in English Grammar?

A subject is the word or group of words that identifies the person, animal, place, thing, or idea that a sentence is about. In many sentences, the subject performs the action expressed by the verb. However, the subject does not always perform an action. It may also be the person or thing being described or affected by an action.

Consider these examples:

1. John works in a bank.

2. The students are preparing for their examinations.

3. My new laptop is expensive.

4. The manager approved the application.

5. Honesty is an important quality.

In the first sentence, John is the subject because the sentence tells us about him. In the second, The students are the subject because the sentence explains what they are doing. In the third, My new laptop is the subject because the sentence describes it. In the fourth, The manager is the subject because the manager performs the action of approving the application. In the fifth, Honesty is the subject because the sentence makes a statement about that quality.

These examples demonstrate that a subject does not have to be a person. It can be an object, an animal, a place, an activity, or an abstract idea. An abstract idea is something that cannot usually be touched or physically seen, such as honesty, courage, happiness, or knowledge.

1.1 The Subject Usually Answers Who or What

One practical way to identify the subject is to ask who or what the sentence is about. In an action sentence, you can often ask who or what performs the action.

For example:

The teacher explained the lesson.

Ask: Who explained the lesson?

Answer: The teacher.

Therefore, The teacher is the subject.

Consider another example:

The examination begins tomorrow.

Ask: What begins tomorrow?

Answer: The examination.

Therefore, The examination is the subject.

However, the who-or-what method should be used carefully. It is a useful starting point, not a complete grammatical test for every sentence. In passive sentences, for example, the subject may receive an action rather than perform it.

Consider:

The application was approved by the manager.

The application did not perform the action of approving. Instead, it received the action. Nevertheless, The application is the subject because it is the grammatical subject of the sentence.

1.2 The Subject Can Be One Word or a Group of Words

A subject does not always consist of one word. It may contain several words that work together to identify the person or thing being discussed.

For example:

The experienced English teacher explained the difficult grammar rule.

The complete subject is The experienced English teacher. The main noun is teacher, while The, experienced, and English provide additional information about that noun.

Consider these additional examples:

The complete subject includes all the words that belong to the subject. The main noun or pronoun that forms its central element is called the simple subject.

Understanding this distinction helps learners avoid identifying only part of the subject when analysing longer sentences.

1.3 The Subject Can Be a Noun, Pronoun, or Other Grammatical Construction

Subjects are commonly nouns or pronouns, but they can also be other grammatical constructions that perform the subject function.

Noun as subject

A student asked a question.

The noun student identifies the person being discussed.

Pronoun as subject

She answered the question correctly.

The pronoun She replaces a noun or noun phrase and functions as the subject.

Gerund phrase as subject

Learning English requires regular practice.

The expression Learning English is a gerund phrase. A gerund is the -ing form of a verb used as a noun. Here, the entire phrase functions as the subject.

Infinitive phrase as subject

To communicate effectively requires confidence and preparation.

The expression To communicate effectively is an infinitive phrase functioning as the subject.

Noun clause as subject

What you said surprised everyone.

The clause What you said functions as the subject of the sentence. It contains its own subject and verb, but the entire clause performs the subject function in the larger sentence.

1.4 Subjects in Questions

In ordinary statements, the subject usually appears before the verb. However, in many questions, the subject may appear after an auxiliary verb.

An auxiliary verb is a helping verb used with another verb or to form a question, negative statement, or particular tense. Common auxiliary verbs include is, are, was, were, do, does, did, have, has, had, will, and can.

Consider:

Has the candidate submitted the application?

The subject is the candidate, not Has. The auxiliary verb Has appears before the subject because the sentence is a question.

More examples:

To identify the subject in a question, look for the person or thing being asked about rather than automatically selecting the first word.

1.5 Subjects in Imperative Sentences

An imperative sentence gives an instruction, command, request, or direction. In many imperative sentences, the subject is not directly written because it is understood to be you.

For example:

• Open the door.

• Please submit your application.

• Listen carefully.

• Complete the assignment before Friday.

In these sentences, the understood subject is you.

The complete meaning of Open the door is approximately You open the door. However, English normally omits the subject in ordinary imperative constructions because the person receiving the instruction is already understood.

This is important because learners sometimes assume that every sentence must visibly contain a subject. Imperative sentences show that an understood subject can exist without appearing as a separate word.

Assignment 1: Understanding the Subject

Instructions: Answer the questions below. Identify the subject in each sentence and explain your choice where requested.

1. What is a subject in English grammar?

2. Identify the subject in: The principal addressed the students.

3. Identify the subject in: My younger sister studies medicine.

4. What is the subject in: Honesty builds trust.

5. Identify the complete subject in: The hardworking employees completed the project.

6. Identify the subject in: Has the teacher marked the scripts?

7. What is the understood subject in: Please close the window.

8. Identify the subject phrase in: Learning a new language takes time.

9. Identify the subject in: The application was rejected.

10. Write three original sentences with different types of subjects.

2. What Is a Predicate in English Grammar?

A predicate is the part of a sentence that tells us something about the subject. It normally contains a verb and may include other words that complete or explain the meaning of that verb.

Consider this sentence:

The young woman prepared for her job interview.

The subject is The young woman. The predicate is prepared for her job interview.

The predicate tells us what the young woman did. Without it, the sentence would not communicate the complete information intended by the writer.

Study these examples:

The predicate may express an action, a condition, a state of being, or a description. It does not always describe something the subject physically does.

2.1 The Predicate Usually Contains a Verb

A verb is a word that expresses an action, occurrence, or state of being. Since the predicate tells us something about the subject, it normally contains the main verb or a verb phrase.

Examples:

• The children played outside.

• The manager is speaking.

• The applicant has submitted the documents.

• My mother became a teacher.

• The room looks beautiful.

In the first example, played is the verb. In the second, is speaking is the verb phrase. In the third, has submitted forms the verb phrase. In the fourth, became links the subject to information describing its resulting state. In the fifth, looks links the subject to the description beautiful.

A predicate may contain one verb or several verbs working together. It may also contain objects, complements, and modifiers.

2.2 The Complete Predicate and the Simple Predicate

The complete predicate includes the verb and all the words that belong to the predicate. The simple predicate is the main verb or verb phrase that expresses what is said about the subject.

Consider:

The experienced teacher explained the lesson carefully.

• Complete subject: The experienced teacher

• Simple subject: teacher

• Complete predicate: explained the lesson carefully

• Simple predicate: explained

The complete predicate tells us the full information about what the teacher did. The simple predicate identifies the main action.

Consider more examples:

This distinction is especially useful when analysing long sentences. It helps learners identify the central verb without ignoring the other words that complete the meaning.

2.3 Predicates Can Express Actions

An action predicate tells us what the subject does or what happens to it.

Examples:

1. The employee prepared the report.

2. The students discussed the assignment.

3. The manager called the applicant.

4. The dog chased the ball.

5. The company launched a new product.

In these examples, the predicates express actions performed by the subjects.

However, not all verbs describe physical actions. Some express mental activities, such as think, understand, remember, and believe.

For example:

The candidate understands the instructions.

The predicate is understands the instructions. It expresses a mental state rather than a physical action.

2.4 Predicates Can Express States and Descriptions

Some predicates describe the condition, identity, or characteristics of the subject.

For example:

• The students are ready.

• My uncle is a doctor.

• The room looks clean.

• The weather became colder.

• Her explanation sounds reasonable.

These sentences do not primarily tell us about physical actions. They describe the subject or identify what it is.

Words such as am, is, are, was, and were are forms of the verb be. They are frequently used to connect a subject with a description or identity.

A verb that links the subject to a subject complement is called a linking verb. A subject complement is a word or phrase that describes or identifies the subject.

For example, in The applicant is confident, the word confident describes the subject The applicant. It is not an object receiving an action.

2.5 The Predicate May Contain an Object or Complement

Some predicates contain additional information needed to complete the meaning of the verb.

An object is a noun, pronoun, or noun phrase that receives the action of a transitive verb or is otherwise required by the verb’s grammatical structure.

For example:

The manager approved the application.

The predicate is approved the application. The word application is the direct object because it receives the action of the verb approved.

A complement is a word or group of words that completes the meaning of another element in a sentence. For example:

The applicant became a supervisor.

The predicate is became a supervisor. The expression a supervisor identifies what the applicant became. It is a subject complement.

The following table illustrates the difference:

The predicate is therefore not limited to the verb alone. It can contain several grammatical elements that explain what happens, to whom it happens, where it happens, or what condition the subject is in.

Assignment 2: Understanding the Predicate

Instructions: Identify the predicate in each sentence. Where necessary, identify the simple predicate and the complete predicate separately.

1. What is a predicate?

2. Identify the predicate in: The children are playing outside.

3. Identify the complete predicate in: My supervisor reviewed the report yesterday.

4. Identify the simple predicate in: The students have completed their assignments.

5. What is the predicate in: The examination was difficult.

6. Identify the object in: The teacher explained the lesson.

7. Identify the subject complement in: My brother is an engineer.

8. Identify the predicate in: The applicant answered the questions confidently.

9. Explain the difference between a simple predicate and a complete predicate.

10. Write three original sentences with different types of predicates.

3. The Difference Between Subject and Predicate

The subject and predicate perform different but connected functions in a sentence. The subject identifies who or what the sentence is about, while the predicate communicates information about that subject.

Consider:

The experienced nurse assisted the patient.

The subject is The experienced nurse. The predicate is assisted the patient.

The subject introduces the person being discussed. The predicate explains the action associated with that person.

This relationship is central to sentence construction. A subject without a suitable predicate usually leaves the reader waiting for more information. Similarly, a predicate without an identifiable subject may be incomplete, except in constructions where the subject is understood or grammatically omitted.

3.1 Subject Versus Predicate: A Detailed Comparison

The position of the subject and predicate can change in some sentence constructions. For example, questions may place an auxiliary verb before the subject. Nevertheless, the grammatical functions remain distinct.

3.2 How to Separate Subject and Predicate

You can use a practical method to identify both parts.

Step 1: Read the complete sentence.

Do not analyse only the first few words. Read the sentence to understand its full meaning.

Step 2: Identify the main verb.

Look for the word or group of words that expresses the action, occurrence, or state.

Step 3: Ask who or what the sentence is about.

Identify the noun, pronoun, or grammatical construction connected to the verb.

Step 4: Mark the complete subject.

Include the descriptive words and phrases that belong to the subject.

Step 5: Mark the complete predicate.

Include the verb and the words that belong to the predicate.

Consider this example:

The hardworking students in our department completed the examination successfully.

• Main verb: completed

• Complete subject: The hardworking students in our department

• Complete predicate: completed the examination successfully

The phrase in our department gives additional information about the students. It belongs to the complete subject because it modifies the noun students.

The words the examination successfully belong to the predicate because they provide information about the action expressed by completed.

3.3 Examples of Subject and Predicate in Different Sentences

Example 1:

The baby is sleeping.

• Subject: The baby

• Predicate: is sleeping

Example 2:

My parents and my uncle attended the ceremony.

• Subject: My parents and my uncle

• Predicate: attended the ceremony

Example 3:

The young man who applied for the position has received an invitation.

• Subject: The young man who applied for the position

• Predicate: has received an invitation

Example 4:

Although the examination was difficult, the students performed well.

This sentence contains more than one clause.

• Dependent clause: Although the examination was difficult

• Independent clause: the students performed well

In the independent clause, the subject is the students, and the predicate is performed well. In the dependent clause, the subject is the examination, and the predicate is was difficult.

This example shows why it is important to recognise clauses when analysing longer sentences. A sentence can contain more than one subject-predicate relationship.

3.4 Subject and Predicate in Questions

Questions often change the ordinary word order of a statement.

Compare:

• Statement: The manager is available.

• Question: Is the manager available?

In both sentences, the subject is the manager. The predicate is is available.

The auxiliary verb is moves before the subject to form the question. However, it remains part of the predicate.

More examples:

3.5 Subject and Predicate in Negative Sentences

Negative sentences express that something is not true, does not happen, or is not permitted.

For example:

The applicant did not attend the interview.

• Subject: The applicant

• Predicate: did not attend the interview

The word not is part of the predicate because it modifies the verb phrase.

Other examples include:

• The students are not ready.

• My manager has not approved the request.

• She cannot attend the meeting.

• The company does not employ temporary workers.

The negative word does not become the subject. It remains part of the predicate.

Assignment 3: Distinguishing Subject and Predicate

Instructions: Separate each sentence into its complete subject and complete predicate.

1. The young teacher explained the topic.

2. My friends and I attended the seminar.

3. The new employee has completed the training.

4. The children in the classroom are making noise.

5. The company did not approve the application.

6. Has your brother returned from work?

7. The woman who lives next door is a nurse.

8. Although the weather was unpleasant, the visitors enjoyed the event.

9. The manager and the supervisor reviewed the documents.

10. Write five sentences and underline the subject in each one. Identify the predicate separately.

4. Types of Subjects in English Grammar

Subjects can take different forms depending on the number of people or things involved and the grammatical construction used. Understanding these forms helps learners recognise how subjects work in different sentence patterns.

4.1 Simple Subject

A simple subject is the main noun or pronoun that identifies what the sentence is about. It does not include all the descriptive words surrounding it.

Example:

The intelligent student answered the question.

The complete subject is The intelligent student, but the simple subject is student.

More examples:

The simple subject is particularly useful when studying subject-verb agreement because it helps identify the central noun or pronoun controlling the verb.

4.2 Complete Subject

The complete subject consists of the simple subject and all the words that describe or identify it.

Example:

The hardworking students in the science department passed the examination.

Complete subject: The hardworking students in the science department.

Simple subject: students.

The complete subject includes the article The, the adjective hardworking, the noun students, and the modifying phrase in the science department.

A common mistake is to identify only the simple subject when a question asks for the complete subject. Always read the instruction carefully.

4.3 Compound Subject

A compound subject consists of two or more subjects that share the same predicate.

Examples:

1. John and Mary attended the meeting.

2. The teacher and the principal welcomed the visitors.

3. My brother, my sister, and I prepared dinner.

4. Honesty and patience are important qualities.

In the first sentence, John and Mary form a compound subject. Both are connected to the verb attended.

Compound subjects are commonly joined by coordinating conjunctions such as and or by structures such as both … and.

However, not every subject joined by or or nor follows the same agreement pattern as a subject joined by and. The choice of verb may depend on number and proximity, which will be discussed in the section on subject-verb agreement.

4.4 Implied Subject

An implied subject is a subject that is understood from the sentence even though it is not directly expressed.

This commonly occurs in imperative sentences.

Examples:

• Stand up.

• Read the instructions.

• Please call me tomorrow.

• Do not enter the room.

In each example, the implied subject is you.

The sentence Read the instructions is understood as You read the instructions. English normally omits the pronoun in this type of command.

4.5 Grammatical Subject and Logical Subject

The grammatical subject is the noun or noun phrase that functions as the subject of the clause. The logical subject is the person or thing that performs or experiences the action in terms of meaning.

These may be different in passive constructions.

Compare:

• Active: The manager approved the application.

• Passive: The application was approved by the manager.

In the active sentence, the manager is both the grammatical subject and the person performing the action.

In the passive sentence, the application is the grammatical subject, although it receives the action. The manager remains the person performing the action, expressed in the by-phrase.

This distinction is important because identifying the subject does not always mean identifying the person who performs the action.

Assignment 4: Types of Subjects

Instructions: Identify the type of subject in each example. Where appropriate, identify the simple subject and complete subject.

1. The beautiful house belongs to my uncle.

2. John and Peter are classmates.

3. Please submit your documents.

4. The students in the library are reading.

5. My mother and father attended the ceremony.

6. The application was approved by the director.

7. Honesty and kindness make relationships stronger.

8. She has completed the assignment.

9. Close the door quietly.

10. Explain the difference between a simple subject and a complete subject.

5. Types of Predicates in English Grammar

Predicates can be classified according to their grammatical structure and the information they communicate. Two particularly useful classifications are the simple and complete predicate, and the distinction between a compound predicate and a predicate containing complements.

5.1 Simple Predicate

A simple predicate is the main verb or verb phrase that tells what the subject does or what condition it is in.

Examples:

• The child laughed.

• My sister is studying.

• The manager has arrived.

• The candidates will participate.

The simple predicates are laughed, is studying, has arrived, and will participate.

Notice that a simple predicate can contain more than one word when auxiliary verbs help form a tense, aspect, or other verb construction.

5.2 Complete Predicate

A complete predicate includes the simple predicate and all the words that complete or modify it.

Example:

The young applicant answered every question confidently.

• Simple predicate: answered

• Complete predicate: answered every question confidently

The complete predicate includes the verb, the object every question, and the adverb confidently.

More examples:

5.3 Compound Predicate

A compound predicate occurs when one subject has two or more verbs or verb phrases that share the same subject.

Examples:

1. The teacher entered the classroom and greeted the students.

2. My brother washed the car and cleaned the garage.

3. The candidate introduced herself, answered the questions, and thanked the panel.

4. The manager reviewed the application but postponed the final decision.

In the first example, entered the classroom and greeted the students are connected to the same subject, The teacher.

A compound predicate does not automatically make a sentence compound. The sentence may still be simple because it contains only one independent clause.

Compare:

• Simple sentence with a compound predicate: The teacher entered the classroom and greeted the students.

• Compound sentence: The teacher entered the classroom, and the students greeted her.

In the first sentence, one subject performs both actions. In the second, each independent clause has its own subject.

5.4 Predicate With a Direct Object

A direct object is a noun, pronoun, or noun phrase that receives the action of a transitive verb.

Example:

The secretary prepared the report.

Subject: The secretary.

Predicate: prepared the report.

Direct object: the report.

The verb prepared expresses an action, and the report identifies what was prepared.

Other examples:

• She answered the question.

• The manager signed the document.

• The students completed the assignment.

5.5 Predicate With a Subject Complement

A subject complement follows a linking verb and describes or identifies the subject.

Examples:

• The woman is a teacher.

• The food smells delicious.

• The candidate seems confident.

• The weather became cold.

In The woman is a teacher, the expression a teacher identifies the subject. It is a subject complement, not an object.

This distinction matters because a linking verb does not transfer an action to an object in the way a transitive action verb does.

5.6 Predicate With an Adverbial

An adverbial is a word, phrase, or clause that provides information about circumstances such as time, place, manner, reason, or frequency.

Examples:

• The students studied in the library.

• The manager arrived yesterday.

• She answered confidently.

• The employees worked after the meeting.

The expressions in the library, yesterday, confidently, and after the meeting add information to the predicates.

Adverbials help make sentences more informative, but they do not change the basic distinction between subject and predicate.

Assignment 5: Types of Predicates

Instructions: Study each sentence and answer the questions.

1. Identify the simple predicate in: The manager has approved the application.

2. Identify the complete predicate in: The students completed their work before lunch.

3. Identify the compound predicate in: The nurse checked the patient and recorded the results.

4. Explain why a compound predicate does not necessarily make a sentence compound.

5. Identify the direct object in: The secretary prepared the documents.

6. Identify the subject complement in: The applicant became a manager.

7. Identify the adverbial in: The children played outside.

8. Write a simple sentence with a compound predicate.

9. Write a sentence containing a subject complement.

10. Explain the difference between a direct object and a subject complement.

6. Subject-Verb Agreement: The Relationship Between Subject and Predicate

One of the most important rules involving subjects and predicates is subject-verb agreement. This means that the verb must agree with its subject in grammatical number and person.

In simple terms, a singular subject generally takes a singular verb in the present tense, while a plural subject generally takes a plural verb.

Consider:

• The student works hard.

• The students work hard.

The first sentence uses works because the student is singular. The second uses work because the students is plural.

Subject-verb agreement is important because an incorrect verb form can make a sentence grammatically awkward or incorrect.

6.1 Singular Subjects Take Singular Verbs

A singular subject refers to one person, animal, place, thing, or idea.

Examples:

• The boy plays football.

• My mother cooks delicious meals.

• The manager approves applications.

• The company offers training.

• Honesty builds trust.

In the simple present tense, many regular verbs take an -s or -es ending when used with third-person singular subjects such as he, she, it, or a singular noun.

For example:

6.2 Plural Subjects Take Plural Verbs

A plural subject refers to more than one person or thing.

Examples:

• The boys play football.

• My parents work in Lagos.

• The managers approve applications.

• The students study English.

• The employees attend meetings.

In the simple present tense, plural subjects generally use the base form of the verb.

Remember that I and you take the base form of most ordinary verbs in the simple present tense, even though I is singular.

For example:

• I work every day.

• You work every day.

6.3 Subject-Verb Agreement With Compound Subjects

When two or more subjects are joined by and, they generally take a plural verb.

Examples:

• John and Peter are friends.

• The teacher and the principal have arrived.

• My mother and father work together.

However, when two nouns joined by and refer to one combined idea, one person, or one unit, a singular verb may be appropriate.

Example:

Fish and chips is a popular meal.

Here, the expression is treated as the name of one dish.

Another example:

The owner and manager is attending the meeting.

This sentence suggests that one person is both the owner and the manager. If two different people are intended, the sentence should be:

The owner and the manager are attending the meeting.

6.4 Agreement With Subjects Joined by Either…Or and Neither…Nor

When subjects are joined by either … or or neither … nor, the verb generally agrees with the subject closest to it in standard English usage.

Examples:

• Either the manager or the employees are attending the meeting.

• Either the employees or the manager is attending the meeting.

• Neither the teacher nor the students are ready.

• Neither the students nor the teacher is ready.

When the two subjects differ in number, the sentence may sound awkward. A useful writing technique is to rearrange the sentence so that the subjects have the same number or so that the wording is more natural.

For example:

The manager or the employees will attend the meeting.

This construction avoids an awkward agreement pattern because will does not change form according to the number of the subject.

6.5 Agreement With Indefinite Pronouns

Indefinite pronouns refer to people or things without identifying them precisely.

Some indefinite pronouns are grammatically singular:

• Everyone

• Everybody

• Someone

• Somebody

• Anyone

• Anybody

• Nobody

• Each

• Either

• Neither

Examples:

• Everyone is ready.

• Somebody has called you.

• Each of the students is responsible.

• Neither of the answers is correct.

Although everyone refers to several people in meaning, it is grammatically singular in standard agreement.

Other indefinite pronouns, such as both, few, many, and several, are plural.

Examples:

• Both are correct.

• Several have applied.

• Many were absent.

Some indefinite pronouns, including all, some, most, and none, can take singular or plural verbs depending on the noun or meaning they refer to.

Examples:

• Some of the water is missing.

• Some of the students are absent.

6.6 Agreement When Words Come Between the Subject and Verb

A common error occurs when learners choose a verb according to a nearby noun rather than the actual subject.

Consider:

The box of books is heavy.

The subject is The box, not books. Therefore, the singular verb is is correct.

Another example:

The students in the classroom are quiet.

The subject is The students. The phrase in the classroom does not change the number of the subject.

Compare these examples:

6.7 Agreement With Collective Nouns

A collective noun refers to a group of people, animals, or things considered as a unit.

Examples include:

• Team

• Family

• Committee

• Government

• Audience

• Class

• Group

In American English, collective nouns generally take singular verbs when the group is considered as one unit.

Examples:

• The team is ready.

• The committee has reached a decision.

• My family lives in Lagos.

In British English, collective nouns may take singular or plural verbs depending on whether the group is viewed as one unit or as individual members.

For example:

• The team is playing well.

• The team are arguing among themselves.

The choice depends on the variety of English and the intended meaning. For a learner using American English, the singular form is generally the safest choice when the group is treated as a unit.

6.8 Agreement With There Is and There Are

The expressions there is and there are introduce the existence or presence of something.

The verb agrees with the noun phrase that follows it.

Examples:

• There is a book on the table.

• There are three books on the table.

• There is an important meeting tomorrow.

• There are several applicants waiting outside.

The word there is not the subject in the usual sense of identifying the thing that exists. The noun phrase following the verb determines whether the verb should be singular or plural.

In everyday speech, some speakers use there’s before plural nouns, but in formal writing and standard examination English, use there are with plural subjects.

6.9 Agreement With Uncountable Nouns

Uncountable nouns refer to things that are not normally counted as separate individual units.

Examples include:

• Information

• Advice

• Equipment

• Furniture

• Knowledge

• Water

• Money

These nouns generally take singular verbs.

Examples:

• The information is useful.

• The advice was helpful.

• The equipment needs repair.

• The furniture looks expensive.

Do not use plural verbs merely because the noun refers to a large quantity.

For example:

Incorrect: The information are correct.

Correct: The information is correct.

Assignment 6: Subject-Verb Agreement

Instructions: Choose the correct verb or rewrite each sentence correctly.

1. The student (work/works) hard.

2. My parents (is/are) at home.

3. The list of applicants (is/are) ready.

4. Everybody (has/have) a responsibility.

5. Neither the teacher nor the students (is/are) available.

6. The team (is/are) preparing for the competition. Use standard American English.

7. There (is/are) three books on the desk.

8. The information (is/are) correct.

9. John and Peter (was/were) absent yesterday.

10. Explain why The box of books is heavy is grammatically correct.

7. Subject and Predicate in Different Sentence Structures

Subject and predicate can appear in simple, compound, complex, and compound-complex sentences. Understanding how they function in these structures makes it easier to analyse longer sentences.

7.1 Subject and Predicate in Simple Sentences

A simple sentence contains one independent clause. It has one subject-predicate relationship, although the subject or predicate may contain several words or coordinated elements.

Examples:

The teacher explained the lesson.

Subject: The teacher.

Predicate: explained the lesson.

My brother and my sister work together.

Subject: My brother and my sister.

Predicate: work together.

The candidate entered the office and greeted the panel.

Subject: The candidate.

Predicate: entered the office and greeted the panel.

The third example contains a compound predicate, but it remains a simple sentence because it has only one independent clause.

7.2 Subject and Predicate in Compound Sentences

A compound sentence contains at least two independent clauses. Each independent clause has its own subject and predicate.

Example:

The manager reviewed the report, and the director approved it.

First clause:

• Subject: The manager

• Predicate: reviewed the report

Second clause:

• Subject: the director

• Predicate: approved it

The coordinating conjunction and connects the two independent clauses.

Another example:

The students prepared for the examination, but the teacher changed the timetable.

First clause:

• Subject: The students

• Predicate: prepared for the examination

Second clause:

• Subject: the teacher

• Predicate: changed the timetable

7.3 Subject and Predicate in Complex Sentences

A complex sentence contains one independent clause and at least one dependent clause.

Example:

Because the examination was difficult, the students studied carefully.

Dependent clause:

• Subject: the examination

• Predicate: was difficult

Independent clause:

• Subject: the students

• Predicate: studied carefully

The dependent clause gives the reason for the action in the independent clause.

Another example:

The candidate smiled when the interviewer entered the room.

Independent clause:

• Subject: The candidate

• Predicate: smiled

Dependent clause:

• Subject: the interviewer

• Predicate: entered the room

A sentence can therefore contain more than one subject and predicate relationship even though it has only one main independent clause.

7.4 Subject and Predicate in Compound-Complex Sentences

A compound-complex sentence contains at least two independent clauses and at least one dependent clause.

Example:

Although the interview was challenging, the candidate answered confidently, and the panel was impressed.

Dependent clause:

• Subject: the interview

• Predicate: was challenging

First independent clause:

• Subject: the candidate

• Predicate: answered confidently

Second independent clause:

• Subject: the panel

• Predicate: was impressed

This sentence contains three subject-predicate relationships. The dependent clause provides background information, while the two independent clauses communicate the main events.

7.5 Subject and Predicate in Passive Sentences

In a passive sentence, the subject receives the action rather than performing it.

Example:

The documents were signed by the manager.

Subject: The documents.

Predicate: were signed by the manager.

The manager performs the action, but The documents is the grammatical subject.

Compare:

In each passive sentence, the grammatical subject is the person or thing receiving the action.

1. The teacher explained the lesson.

2. The teacher explained the lesson, and the students took notes.

3. When the teacher arrived, the students became quiet.

4. Although the task was difficult, the employees completed it, and the manager praised them.

5. The application was approved by the director.

7. The manager entered the office and greeted the visitors.

8. The candidate smiled when the interviewer arrived.

9. Explain why a compound sentence contains more than one subject-predicate relationship.

10. Write one compound-complex sentence and identify every subject and predicate in it.

8. Common Mistakes Learners Make When Identifying Subjects and Predicates

Learners sometimes confuse subjects and predicates because they focus on individual words instead of understanding how those words function in a sentence. The following mistakes are common in grammar exercises and everyday writing.

8.1 Confusing the Simple Subject With the Complete Subject

Incorrect identification:

Sentence: The intelligent young student answered the question.

Subject: student.

This answer identifies the simple subject, but not the complete subject.

Correct identification:

Complete subject: The intelligent young student.

Simple subject: student.

The mistake occurs because learners sometimes ignore descriptive words that belong to the subject. Remember that the complete subject includes the main noun and its modifiers.

8.2 Identifying Only the Verb as the Complete Predicate

Incorrect identification:

Sentence: The manager approved the application yesterday.

Predicate: approved.

The word approved is the simple predicate, not the complete predicate.

Correct identification:

Simple predicate: approved.

Complete predicate: approved the application yesterday.

The complete predicate includes all the words that belong to the predicate, not just the main verb.

8.3 Mistaking a Compound Predicate for a Compound Sentence

Incorrect assumption:

The teacher entered the classroom and greeted the students is a compound sentence.

Correct explanation:

It is a simple sentence with a compound predicate. The subject The teacher performs both actions.

Compare:

The teacher entered the classroom, and the students greeted her.

This is a compound sentence because it contains two independent clauses, each with its own subject.

8.4 Assuming the First Word Is Always the Subject

Incorrect identification:

Sentence: Is the manager available?

Subject: Is.

Correct identification:

Subject: the manager.

The word Is is an auxiliary verb placed before the subject to form a question.

Learners should identify the grammatical role of each word rather than assume that the first word must be the subject.

8.5 Confusing the Object With the Subject

Incorrect identification:

Sentence: The teacher praised the student.

Subject: the student.

Correct identification:

Subject: The teacher.

Object: the student.

The teacher performs the action of praising. The student receives that action.

In passive sentences, however, the object of an active sentence may become the subject of the passive sentence.

For example:

The student was praised by the teacher.

Here, The student is the grammatical subject.

8.6 Assuming Every Sentence Must Show Its Subject

Incorrect assumption:

Close the door has no subject.

Correct explanation:

The subject is understood to be you. Imperative sentences commonly omit the subject because the person receiving the instruction is understood.

8.7 Choosing a Verb According to the Nearest Noun

Incorrect:

The quality of the products are excellent.

Correct:

The quality of the products is excellent.

The subject is The quality, which is singular. The plural noun products appears inside a prepositional phrase and does not control the verb.

8.8 Confusing Subject Complements With Objects

Incorrect identification:

Sentence: The woman is a teacher.

Object: a teacher.

Correct identification:

Subject complement: a teacher.

The linking verb is connects the subject to information identifying it. The expression a teacher does not receive an action.

8.9 Treating Every Group of Words as a Subject or Predicate

Incorrect assumption:

Every group of words containing a noun must be a complete subject.

Correct explanation:

A sentence must be analysed according to its grammatical structure. A phrase may contain a noun but function as part of the predicate or as a modifier.

For example:

The manager spoke to the employees.

The expression to the employees contains a noun phrase, but it belongs to the predicate. It is not the subject.

8.10 Ignoring Clauses in Longer Sentences

Consider:

When the meeting ended, the employees returned to their offices.

A learner may identify only the employees as the subject and returned to their offices as the predicate. That is correct for the independent clause, but it overlooks the dependent clause.

A complete analysis identifies:

• Dependent clause subject: the meeting

• Dependent clause predicate: ended

• Independent clause subject: the employees

• Independent clause predicate: returned to their offices

When a sentence contains multiple clauses, identify the subject and predicate of each clause separately.

Assignment 8: Correcting Common Errors

Instructions: Correct each error or explain why the original analysis is wrong.

1. In The beautiful house belongs to my uncle, a learner identifies only house as the complete subject. Explain the problem.

2. In The manager reviewed the document yesterday, a learner identifies reviewed as the complete predicate. Correct the analysis.

3. Explain why The teacher entered the room and greeted the students is not necessarily a compound sentence.

4. Identify the subject in: Does your sister speak English?

5. Identify the subject and object in: The interviewer questioned the candidate.

6. Identify the implied subject in: Please wait outside.

7. Correct: The list of students are on the table.

8. Identify the subject complement in: The candidate seems confident.

9. Identify the subject and predicate in both clauses of: Although the road was narrow, the driver continued carefully.

10. Write three examples of common subject or predicate errors and correct them.

9. How to Use Subjects and Predicates in Job Interviews and Professional Communication

Understanding subjects and predicates is not only useful for passing grammar examinations. It also helps people communicate professionally, particularly during job interviews, workplace discussions, presentations, and formal correspondence.

When answering an interview question, you need to express complete thoughts. A well-formed sentence identifies the person or thing being discussed and provides the necessary information about it.

For example, when asked about your experience, you might say:

I have three years of experience in customer service.

Subject: I.

Predicate: have three years of experience in customer service.

The sentence is direct and complete. It communicates your experience without unnecessary wording.

9.1 Constructing Clear Interview Answers

Interview answers should communicate the candidate’s qualifications and experiences in a logical way.

Consider the question:

Why should we employ you?

An incomplete response might be:

Because I have relevant experience.

This is a dependent clause beginning with because. It does not normally stand alone as a complete answer in formal writing.

A more complete response is:

You should employ me because I have relevant experience and strong communication skills.

Subject: You.

Predicate: should employ me because I have relevant experience and strong communication skills.

Another possible response is:

I believe I am suitable for this position because my experience matches the requirements.

The sentence contains a main clause and a dependent clause, allowing the candidate to state an opinion and explain the reason behind it.

9.2 Using Subjects and Predicates in Professional Emails

Professional emails require complete sentences that communicate information clearly.

Consider:

I am writing to confirm my interview appointment.

Subject: I.

Predicate: am writing to confirm my interview appointment.

Another example:

The attached document contains the requested information.

Subject: The attached document.

Predicate: contains the requested information.

These sentences are clear because their subjects identify the people or things being discussed, while their predicates provide the necessary information.

Avoid incomplete expressions such as:

• Because I need further clarification.

• When I receive your response.

• Although I have completed the assignment.

These expressions are dependent clauses. They can be used as parts of longer sentences, but they generally need an independent clause to communicate a complete thought.

For example:

I am requesting further clarification because I need additional information.

9.3 Avoiding Unnecessarily Complicated Sentences

Professional communication should be clear. Using a long sentence does not automatically make a person sound intelligent or educated.

Compare:

I possess the necessary qualifications, and I have relevant experience.

This is a clear compound sentence.

Now consider:

Although I possess the necessary qualifications and have relevant experience, I would like to explain that I also have the ability to work effectively with different teams.

This is grammatically acceptable, but it may be unnecessarily long depending on the context.

A more direct version might be:

I possess the necessary qualifications and relevant experience. I also work effectively with different teams.

Both versions can be correct. The choice depends on the information being emphasised and the communication situation.

9.4 Building Strong Professional Statements

You can use the following patterns to construct clear statements.

9.5 Practising Subject and Predicate Through Speaking

A useful exercise is to practise identifying the subject and predicate in sentences you use during everyday conversations.

For example, say:

I enjoy working with people.

Then identify:

• Subject: I

• Predicate: enjoy working with people

Next, expand the sentence:

I enjoy working with people because I like helping customers solve problems.

The sentence now contains a main clause and a dependent clause. Identifying both relationships helps you understand how your ideas are connected.

Practise with sentences about your education, experience, skills, interests, and career goals. This approach helps you build accurate sentences without memorising complicated grammatical definitions.

11. Conclusion

The subject and predicate are two fundamental elements of English sentence structure. The subject identifies who or what a sentence is about, while the predicate tells us something about that subject. Understanding how they work together helps learners construct complete sentences, recognise grammatical relationships, and communicate ideas more accurately.

The subject may be a noun, pronoun, noun phrase, gerund phrase, infinitive phrase, or clause. It may be simple, complete, compound, or implied. The predicate contains the verb or verb phrase and may include objects, complements, and modifiers that provide additional information.

You should also remember the difference between a simple predicate and a complete predicate. The simple predicate identifies the main verb or verb phrase, while the complete predicate includes all the words that belong to the predicate. Similarly, a compound subject contains two or more subjects sharing a predicate, whereas a compound predicate contains two or more verbs or verb phrases sharing one subject.

Subject-verb agreement is another important part of this topic. Singular and plural subjects must generally agree with their verbs, and learners must be careful when sentences contain collective nouns, indefinite pronouns, compound subjects, and phrases between the subject and verb.

For practical improvement, begin by identifying the subject and predicate in short sentences. Gradually move to longer sentences containing descriptive phrases, objects, complements, and multiple clauses. Practise writing about your education, family, work experience, and career goals. Read your sentences aloud and check whether each one communicates a complete thought.

In professional communication, a clear subject and predicate help you explain your qualifications, answer interview questions, write effective emails, and express your ideas confidently. The goal is not simply to memorise grammatical definitions but to understand how sentences work and use that knowledge in everyday English.

12. Answer Key With Explanations

Use this section after completing the assignments. The explanations show why each answer is correct. For questions requiring original writing, the answers are examples, and other grammatically correct responses are possible.
