Introduction to Subject-Verb Agreement

English grammar plays an important role in effective communication. Whether you are writing an academic essay, preparing a professional email, completing school assignments, or communicating in everyday conversations, using grammatically correct sentences helps you express your thoughts clearly.

One of the most important principles of English grammar is subject-verb agreement. It ensures that the subject and verb in a sentence match correctly in number and person.

For example:

• Incorrect: She go to school every day.

• Correct: She goes to school every day.

In the first sentence, the subject is singular, but the verb does not agree with it. The second sentence uses the correct verb form.

Although the basic concept seems simple, subject-verb agreement becomes more challenging when sentences contain compound subjects, collective nouns, indefinite pronouns, intervening phrases, or complex sentence structures.

This comprehensive guide explains 24 essential rules of subject-verb agreement, with simple explanations and practical examples to help students, parents, teachers, and English learners understand and apply them confidently.

Understanding the Basics of Subject-Verb Agreement

Before exploring the 24 rules, it is important to understand what subjects and verbs are and how they work together in a sentence.

What Is a Subject?

A subject is the person, place, animal, thing, or idea that performs an action or is described in a sentence.

In simple terms, the subject tells us who or what the sentence is about.

Examples:

1. Rahul plays cricket.

2. The dog is barking.

3. My parents work in Pune.

4. Honesty is important.

In these examples, Rahul, the dog, my parents, and honesty are the subjects.

What Is a Verb?

A verb is a word that expresses an action, occurrence, or state of being.

Examples:

1. She writes a letter.

2. They play football.

3. He is happy.

4. We have completed our homework.

Verbs can be classified into different types:

• Action verbs: Run, write, speak, eat, and dance.

• Linking verbs: Is, am, are, was, and were.

• Helping verbs: Has, have, had, do, does, and will.

What Is Subject-Verb Agreement?

Subject-verb agreement is the grammatical rule that requires a verb to match its subject in number and person.

Generally:

• A singular subject takes a singular verb.

• A plural subject takes a plural verb.

Examples:

Important: In the simple present tense, third-person singular subjects generally take verbs ending in -s or -es. Plural subjects generally use the base form. The verb be follows its own forms.

24 Essential Rules of Subject-Verb Agreement

Let’s understand the 24 important rules with explanations and examples.

Rule 1: Singular Subjects Take Singular Verbs

When a sentence has a singular subject, the verb must also be singular.

In the simple present tense, most regular verbs take an -s or -es ending with third-person singular subjects.

Examples:

• She works in an office.

• Rahul plays football.

• My brother studies English.

• The cat sleeps on the sofa.

Incorrect: She work in an office.

Correct: She works in an office.

Rule 2: Plural Subjects Take Plural Verbs

When the subject refers to more than one person, animal, place, or thing, use a plural verb.

Examples:

• The students study together.

• My friends play cricket.

• The birds fly in the sky.

• Teachers explain difficult concepts.

Incorrect: The students studies together.

Correct: The students study together.

Rule 3: Subjects Connected by “And” Usually Take Plural Verbs

When two or more subjects are connected by the conjunction “and”, they generally form a plural subject and require a plural verb.

Examples:

• Rahul and Amit are friends.

• My mother and father work together.

• Mathematics and science are important subjects.

Incorrect: Rahul and Amit is friends.

Correct: Rahul and Amit are friends.

Exception: When two nouns refer to one person, one combined item, or one commonly understood idea, a singular verb may be appropriate.

Example:

– Bread and butter is my favourite breakfast.

Rule 4: Subjects Connected by “Or” or “Nor”

When two subjects are connected by “or” or “nor”, the verb generally agrees with the subject closest to it.

Examples:

• Either the teacher or the students are responsible.

• Neither the students nor the teacher is available.

• Either Rahul or Amit is attending the meeting.

Remember to identify the subject nearest to the verb.

Rule 5: Either…Or and Neither…Nor Require Proximity Agreement

When using either…or or neither…nor, the verb agrees with the subject closest to it.

Examples:

• Either my brother or my parents are coming.

• Neither the employees nor the manager is present.

• Neither the manager nor the employees are available.

This rule is particularly useful when writing longer sentences with two different subjects.

Rule 6: Collective Nouns Usually Take Singular Verbs

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

Examples include:

• Team

• Family

• Committee

• Audience

• Class

• Government

When the group acts as one unit, use a singular verb.

Examples:

• The team is playing well.

• My family lives in Pune.

• The committee has made its decision.

• The audience enjoys the performance.

In British English, collective nouns may also take plural verbs when the members are considered individually.

Example:

– The team are arguing among themselves.

Rule 7: Indefinite Pronouns Usually Take Singular Verbs

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

Some indefinite pronouns always take singular verbs.

Examples:

• Everyone is ready.

• Someone has called you.

• Nobody knows the answer.

• Everybody wants success.

• Each has a different opinion.

Common singular indefinite pronouns include everyone, everybody, someone, somebody, anyone, anybody, nobody, no one, each, and either.

Rule 8: Some Indefinite Pronouns Take Plural Verbs

Certain indefinite pronouns always take plural verbs.

Examples:

• Both are intelligent.

• Few understand the concept.

• Many are interested in learning.

• Several have completed their assignments.

Common plural indefinite pronouns include both, few, many, and several.

Rule 9: Some Indefinite Pronouns Depend on the Noun That Follows

Words such as all, some, most, none, and any can take singular or plural verbs depending on what they refer to.

Examples:

• Some of the water is dirty.

• Some of the students are absent.

• All of the food is fresh.

• All of the players are ready.

The key is to identify whether the noun being referred to is singular, plural, or uncountable.

Rule 10: Subjects Separated from Verbs by Phrases

Sometimes additional words appear between a subject and its verb. These words do not change the subject’s number.

Examples:

• The teacher, along with her students, is attending the event.

• The manager, together with his employees, is working.

• The students, as well as their teacher, are participating.

Remember that expressions such as along with, together with, as well as, and in addition to do not automatically make the subject plural.

Rule 11: Subjects Beginning with “Each” or “Every”

When each or every is used before two or more singular nouns joined by “and”, the subject generally takes a singular verb.

Examples:

• Every boy and girl is participating.

• Each student and teacher has received a certificate.

• Every employee and manager is responsible.

These words emphasise individuals separately, so the singular verb is used.

Rule 12: Titles of Books, Movies, and Other Works Take Singular Verbs

The titles of books, movies, songs, and other creative works are generally treated as singular subjects, even if they contain plural words.

Examples:

• “The Adventures of Tom Sawyer” is an interesting book.

• “The Chronicles of Narnia” is a popular series.

• “Great Expectations” is a famous novel.

The title represents one work, so it takes a singular verb.

Rule 13: Amounts of Money, Time, and Distance Usually Take Singular Verbs

When an amount of money, time, distance, or measurement is considered a single unit, use a singular verb.

Examples:

• Ten thousand rupees is a significant amount.

• Five kilometres is a long distance.

• Two hours is enough for this task.

• Twenty dollars is the price.

However, use a plural verb when the individual units are being considered separately.

Example:

– Two hours have passed since the meeting started.

Rule 14: Uncountable Nouns Take Singular Verbs

Uncountable nouns refer to things that are not normally counted individually.

Examples include information, furniture, advice, water, equipment, and knowledge.

These nouns generally take singular verbs.

Examples:

• The information is useful.

• The furniture looks beautiful.

• Your advice is valuable.

• The equipment needs repair.

Incorrect: The information are useful.

Correct: The information is useful.

Rule 15: Words Between the Subject and Verb Do Not Change Agreement

A common grammatical mistake occurs when writers choose a verb based on a nearby noun instead of the actual subject.

Examples:

• The box of chocolates is on the table.

• The quality of these products is excellent.

• The students in the classroom are attentive.

In the first example, “box” is the subject, not “chocolates”.

Always identify the main subject before selecting the verb.

Rule 16: Subjects Beginning with “There Is” and “There Are”

In sentences beginning with there, the verb agrees with the actual subject that follows it.

Examples:

• There is a book on the desk.

• There are three books on the desk.

• There is a student in the classroom.

• There are many students in the classroom.

Remember that “there” is not the subject in these sentences.

Rule 17: Relative Pronouns Must Agree with Their Antecedents

Relative pronouns such as who, which, and that introduce clauses and refer to nouns or pronouns.

The verb inside the relative clause must agree with the noun or pronoun it refers to.

Examples:

• She is one of the students who work hard.

• He is the only student who works hard.

• I know a teacher who teaches English.

Pay attention to the noun being described by the relative clause.

Rule 18: “A Number Of” and “The Number Of”

These two expressions follow different agreement rules.

A number of means several or many and takes a plural verb.

Example:

– A number of students are absent today.

The number of refers to one specific quantity and takes a singular verb.

Example:

– The number of students is increasing.

This is one of the most commonly tested subject-verb agreement rules in English grammar examinations.

Rule 19: Subjects Connected by “Not Only…But Also”

When two subjects are connected by not only…but also, the verb agrees with the subject closest to it.

Examples:

• Not only Rahul but also his friends are attending.

• Not only the students but also the teacher is excited.

• Not only the manager but also the employees are responsible.

Identify the subject closest to the verb before choosing the correct form.

Rule 20: Gerunds and Infinitives Used as Subjects

A gerund is a verb ending in -ing that functions as a noun.

An infinitive is the base form of a verb preceded by “to”.

When a gerund or infinitive phrase functions as the subject, it generally takes a singular verb.

Examples:

• Swimming is good exercise.

• Reading improves vocabulary.

• To learn English requires practice.

• Playing football is enjoyable.

Even though these activities involve actions, the phrases function as singular subjects.

Rule 21: The Verb “Be” Changes According to the Subject

The verb “be” has different forms depending on the subject and tense.

Present tense:

• I am happy.

• He is happy.

• She is happy.

• They are happy.

Past tense:

• I was tired.

• He was tired.

• They were tired.

• We were tired.

Using the correct form of “be” is essential for grammatically correct sentences.

Rule 22: The Verbs “Have” and “Has”

The verbs have and has are used according to the subject.

Use has with third-person singular subjects.

Use have with I, you, we, and plural subjects.

Examples:

• She has a new laptop.

• Rahul has completed his homework.

• They have completed their assignments.

• We have a meeting today.

• I have a question.

Incorrect: He have a car.

Correct: He has a car.

Rule 23: The Verbs “Do” and “Does”

The auxiliary verbs do and does are used to form questions and negative sentences in the simple present tense.

Use does with third-person singular subjects.

Use do with I, you, we, and plural subjects.

Examples:

• Does she speak English?

• Does Rahul play cricket?

• Do they understand the lesson?

• Do you like reading?

Negative sentences:

• He does not like coffee.

• She does not work here.

• They do not understand the question.

Important: After does or does not, always use the base form of the main verb.

Incorrect: Does she likes music?

Correct: Does she like music?

Rule 24: Inverted Sentences and Questions

In questions and certain sentence structures, the verb may appear before the subject. Even in these situations, subject-verb agreement must be maintained.

Examples:

• Is the teacher available?

• Are the students ready?

• Where is your brother?

• Where are your friends?

• Never have I seen such a beautiful place.

Do not select the verb based on its position. Identify the actual subject and ensure that the verb agrees with it.

Common Subject-Verb Agreement Mistakes to Avoid

Even people with good English communication skills sometimes make subject-verb agreement mistakes. Understanding these common errors can help improve your writing.

How to Avoid These Mistakes

1. Identify the main subject before choosing the verb.

2. Check whether the subject is singular or plural.

3. Do not get confused by nouns appearing between the subject and verb.

4. Pay special attention to indefinite pronouns.

5. Practise using has, have, does, and do.

6. Read your sentences aloud to identify grammatical errors.

7. Proofread your writing before submitting or publishing it.

Practical Applications of Subject-Verb Agreement

Subject-verb agreement is not limited to grammar examinations. It is an essential skill used in academic, professional, and everyday communication.

Subject-Verb Agreement in Essay Writing

Academic writing requires clear sentence structures and accurate grammar.

Students who understand subject-verb agreement can write essays, assignments, reports, and research papers more effectively.

For example:

Incorrect: Technology improve the education system.

Correct: Technology improves the education system.

Correct grammar makes academic writing easier to understand and more professional.

Subject-Verb Agreement in Business Communication

Professional communication requires accuracy and clarity.

Whether you are preparing business emails, presentations, proposals, or reports, correct grammar helps you communicate confidently.

Examples:

• The company provides professional services.

• Our employees work on multiple projects.

• The management has approved the proposal.

• The sales team is preparing the report.

Small grammatical errors can affect the professionalism of business communication.

Subject-Verb Agreement in Everyday Conversations

Correct grammar also improves everyday communication.

Examples:

• My friend lives nearby.

• My friends live nearby.

• She knows the answer.

• They know the answer.

Regular practice helps learners use correct sentence structures naturally.

How Parents and Teachers Can Help Children Learn Subject-Verb Agreement

Children can develop strong English grammar skills through consistent practice, interactive activities, and practical examples.

Parents and teachers can make grammar learning more engaging by introducing simple activities into everyday routines.

1. Use Grammar Games

Create activities in which children match subjects with the correct verbs.

For example:

• He → Plays

• They → Play

• She → Writes

• We → Write

This helps children understand the difference between singular and plural subjects.

2. Encourage Daily Reading

Reading storybooks, short articles, and educational materials exposes children to grammatically correct sentences.

Encourage children to identify subjects and verbs while reading.

3. Practise Sentence Formation

Ask children to create sentences using different subjects and verbs.

For example:

• The boy runs.

• The boys run.

• My sister sings.

• My sisters sing.

4. Provide Constructive Feedback

When children make grammatical mistakes, explain the correct form instead of simply pointing out the error.

For example, if a child says “She go to school”, explain why “She goes to school” is correct.

5. Use Online Learning Platforms

Educational resources can make grammar learning more interactive.

Some useful platforms include:

• Khan Academy – Educational lessons and practice resources.

• Grammarly – Writing assistance and grammar suggestions.

• British Council LearnEnglish – English grammar explanations and exercises.
