Subject-verb agreement is a fundamental aspect of English grammar, ensuring clarity and correctness in writing and speech. It dictates that a verb must agree in number with its subject.
This means that if the subject is singular, the verb must be singular, and if the subject is plural, the verb must be plural. Mastering this concept is crucial for effective communication, as errors in subject-verb agreement can lead to confusion and misinterpretation.
This article provides a comprehensive guide to subject-verb agreement, covering its definition, rules, common mistakes, and advanced topics. Whether you’re a student, a writer, or an English language learner, this guide will help you strengthen your understanding and application of subject-verb agreement.

Definition of Subject-Verb Agreement
Subject-verb agreement, also known as concord, is the correspondence in number between the subject and verb of a sentence. In simpler terms, it means that a singular subject takes a singular verb, and a plural subject takes a plural verb.
This agreement ensures grammatical correctness and enhances the clarity of written and spoken English. The principle applies primarily to the present tense, as the past tense typically uses the same verb form for both singular and plural subjects (with the exception of ‘was’ and ‘were’).
The function of subject-verb agreement is to maintain grammatical consistency within a sentence. It helps readers or listeners understand the relationship between the subject and the action being performed.
Without proper subject-verb agreement, sentences can sound awkward and may lead to confusion. The contexts in which subject-verb agreement is important are varied, ranging from formal writing and academic papers to everyday conversations and professional communications.
It is a foundational element of English grammar that underpins effective communication.
Structural Breakdown
The basic structure of a sentence with subject-verb agreement involves identifying the subject and then choosing the correct verb form to match. The subject is the noun or pronoun that performs the action.
The verb is the word that describes the action. In the present tense, the verb usually changes form depending on whether the subject is singular or plural.
For example:
- Singular: The cat sits on the mat.
- Plural: The cats sit on the mat.
In the first sentence, “cat” is the singular subject, so the verb “sits” is used. In the second sentence, “cats” is the plural subject, so the verb “sit” is used.
The key is to correctly identify the subject and then select the appropriate verb form to ensure agreement.
Understanding the grammatical number of the subject is critical. This involves determining whether the subject is singular (referring to one person, place, thing, or idea) or plural (referring to more than one).
Once the number is identified, the corresponding verb form can be selected. This might seem straightforward, but complexities arise with compound subjects, collective nouns, and indefinite pronouns, which will be discussed later in this article.
Types and Categories of Subjects
Subjects in English grammar can be categorized into several types, each requiring a different approach to subject-verb agreement. Understanding these categories is essential for mastering this grammatical concept.
Singular Subjects
A singular subject refers to one person, place, thing, or idea. Singular subjects typically take singular verbs.
Examples include:
- He walks to school.
- She reads a book.
- It rains often in April.
- The car is red.
- My brother plays the guitar.
Plural Subjects
A plural subject refers to more than one person, place, thing, or idea. Plural subjects typically take plural verbs.
Examples include:
- They walk to school.
- We read books.
- The cars are red.
- My brothers play the guitar.
- Cats sleep during the day.
Compound Subjects
A compound subject consists of two or more subjects joined by a conjunction such as “and,” “or,” or “nor.” The verb form depends on the conjunction used and the nature of the subjects. When subjects are joined by “and,” they usually take a plural verb.
When joined by “or” or “nor,” the verb agrees with the subject closest to it.
- John and Mary are going to the party.
- Neither John nor Mary is going to the party.
- Either the students or the teacher is responsible.
Collective Nouns
Collective nouns refer to a group of people or things as a single unit. These nouns can take either a singular or plural verb, depending on whether the group is acting as a single unit or as individual members. Common collective nouns include team, family, committee, group, and class.
- The team is playing well. (acting as a unit)
- The family are deciding on their vacation plans. (acting as individuals)
Indefinite Pronouns
Indefinite pronouns refer to nonspecific persons or things. Some indefinite pronouns are always singular (e.g., each, every, everyone, someone, nobody), while others are always plural (e.g., both, few, many, several). Some can be either singular or plural, depending on the context (e.g., some, any, none, all, most).
- Everyone is ready to go. (singular)
- Both are invited. (plural)
- Some of the cake is gone. (singular)
- Some of the cookies are gone. (plural)

9 Rules of Subject-Verb Agreement
Understanding the rules of subject-verb agreement is crucial for accurate writing. Here are nine key rules to keep in mind:
Rule 1: Basic Agreement
A singular subject takes a singular verb, and a plural subject takes a plural verb. This is the most fundamental rule of subject-verb agreement.
For example:
- Singular: The dog barks.
- Plural: The dogs bark.
Rule 2: Compound Subjects with ‘and’
When two or more subjects are joined by “and,” they usually take a plural verb. For example:
- John and Mary are going to the party.
- The cat and the dog play together.
However, if the compound subject refers to a single entity or idea, then a singular verb is used. For example:
- Macaroni and cheese is my favorite dish. (referring to a single dish)
Rule 3: Compound Subjects with ‘or’/’nor’
When two or more singular subjects are joined by “or” or “nor,” the verb agrees with the subject closest to it. For example:
- Neither John nor Mary is coming to the party.
- Either the students or the teacher is responsible.
If one subject is singular and the other is plural, the verb agrees with the subject closest to it. For example:
- Neither the teacher nor the students are ready.
- Either the students or the teacher is ready.
Rule 4: Collective Nouns
Collective nouns can take either a singular or plural verb, depending on whether the group is acting as a single unit or as individual members. If the group is acting as a single unit, use a singular verb.
If the group members are acting individually, use a plural verb. For example:
- The team is playing well. (acting as a unit)
- The team are arguing about the strategy. (acting as individuals)
Rule 5: Indefinite Pronouns
Some indefinite pronouns are always singular (e.g., each, every, everyone, someone, nobody), while others are always plural (e.g., both, few, many, several). Some can be either singular or plural, depending on the context (e.g., some, any, none, all, most). For example:
- Everyone is ready to go. (singular)
- Both are invited. (plural)
- Some of the cake is gone. (singular)
- Some of the cookies are gone. (plural)
Rule 6: Phrases Between Subject and Verb
Phrases or clauses that come between the subject and verb do not affect subject-verb agreement. The verb must agree with the actual subject, not with any nouns or pronouns in the intervening phrase.
For example:
- The dog, along with its puppies, is running in the park. (The subject is “dog,” which is singular)
- The students, including John and Mary, are going on a field trip. (The subject is “students,” which is plural)
Rule 7: Subjects Following the Verb
In sentences that begin with “there is” or “there are,” the subject follows the verb. The verb must agree with the subject that follows it.
For example:
- There is a book on the table. (The subject is “book,” which is singular)
- There are books on the table. (The subject is “books,” which is plural)
Rule 8: Nouns Ending in -s
Some nouns that end in “-s” appear plural but are actually singular. These nouns usually refer to a field of study or a disease.
They take a singular verb. For example:
- Mathematics is my favorite subject.
- Measles is a contagious disease.
Rule 9: Titles of Works
The titles of books, movies, and other works are treated as singular, even if they contain plural nouns. They take a singular verb.
For example:
- “The Adventures of Tom Sawyer” is a classic novel.
- “Friends” is a popular TV show.
Common Mistakes in Subject-Verb Agreement
Even experienced writers sometimes make mistakes in subject-verb agreement. Here are some common errors and how to correct them:
Incorrect | Correct | Explanation |
---|---|---|
The dog, along with its puppies, are running in the park. | The dog, along with its puppies, is running in the park. | The verb should agree with the main subject, “dog,” which is singular. |
There is books on the table. | There are books on the table. | The verb should agree with the subject, “books,” which is plural. |
Everyone are going to the party. | Everyone is going to the party. | “Everyone” is a singular indefinite pronoun and takes a singular verb. |
The team are playing well. | The team is playing well. | When the team is acting as a single unit, it takes a singular verb. |
Neither John nor Mary are coming. | Neither John nor Mary is coming. | When subjects are joined by “nor,” the verb agrees with the closest subject, “Mary,” which is singular. |
Mathematics are difficult for me. | Mathematics is difficult for me. | Nouns ending in “-s” that refer to a field of study take a singular verb. |
The Adventures of Tom Sawyer are a great book. | The Adventures of Tom Sawyer is a great book. | Titles of works take a singular verb, even if they contain plural nouns. |
Some of the students is absent. | Some of the students are absent. | “Some” can be plural depending on the context. Here, “students” is plural, so the verb should be plural. |
Each of the students have a book. | Each of the students has a book. | “Each” is a singular indefinite pronoun and takes a singular verb. |
My family are very supportive. | My family is very supportive. | If the family is acting as a single unit, it takes a singular verb. |

Advanced Topics
Beyond the basic rules, there are advanced aspects of subject-verb agreement that can further refine your understanding and usage.
Subjunctive Mood
The subjunctive mood is used to express wishes, suggestions, or hypothetical situations. In the subjunctive mood, the verb form often differs from the indicative mood, and subject-verb agreement rules may be altered.
The most common example is the use of “were” instead of “was” for singular subjects when expressing a wish or hypothetical situation. For example:
- I wish I were taller. (instead of “I wish I was taller”)
- If he were here, he would know what to do. (instead of “If he was here”)
In certain constructions, such as demands or recommendations, the base form of the verb is used, regardless of the subject’s number. For example:
- The doctor recommended that he exercise more. (instead of “exercises”)
- It is essential that everyone be on time. (instead of “is”)
Inverted Sentences
Inverted sentences occur when the verb comes before the subject. This often happens in questions or when using certain adverbs at the beginning of a sentence.
In these cases, it’s important to identify the subject correctly to ensure proper subject-verb agreement. For example:
- Where are the keys? (The subject is “keys,” which is plural, so the verb is “are”)
- There is a cat on the roof. (The subject is “cat,” which is singular, so the verb is “is”)
- Only then did I understand the problem. (The subject is “I,” which takes the verb “did” in this construction)
Relative Clauses
Relative clauses are clauses that begin with relative pronouns such as “who,” “which,” or “that.” The verb in a relative clause must agree with the noun or pronoun that the relative pronoun refers to (the antecedent). This can sometimes be tricky, especially when the antecedent is an indefinite pronoun or a collective noun.
For example:
- He is one of the students who are always on time. (The relative pronoun “who” refers to “students,” which is plural, so the verb is “are”)
- This is the only book that is worth reading. (The relative pronoun “that” refers to “book,” which is singular, so the verb is “is”)
Frequently Asked Questions
What is the most common mistake in subject-verb agreement?
One of the most common mistakes is failing to recognize phrases that come between the subject and the verb. Remember that these phrases do not affect subject-verb agreement.
The verb must agree with the actual subject, not with any nouns or pronouns in the intervening phrase.
How do I handle collective nouns?
Collective nouns can be tricky. If the group is acting as a single unit, use a singular verb.
If the group members are acting individually, use a plural verb. Context is key.
What about indefinite pronouns like “some” or “none”?
Indefinite pronouns like “some,” “any,” “none,” “all,” and “most” can be either singular or plural, depending on the context. Look at the noun or pronoun they refer to.
If it’s singular, use a singular verb. If it’s plural, use a plural verb.
How does subject-verb agreement apply to titles of books or movies?
The titles of books, movies, and other works are treated as singular, even if they contain plural nouns. They take a singular verb.
What if the subject is a gerund or an infinitive?
When the subject of a sentence is a gerund (a verb ending in “-ing” that functions as a noun) or an infinitive (the base form of a verb preceded by “to”), it is treated as singular and takes a singular verb. For example: Swimming is good exercise. To err is human.
How do I deal with sentences that start with “here” or “there”?
In sentences that begin with “here” or “there,” the subject follows the verb. Make sure the verb agrees with the subject that follows it. For example: Here is the book. There are the keys.
What is the subjunctive mood and how does it affect subject-verb agreement?
The subjunctive mood is used to express wishes, suggestions, or hypothetical situations. In the subjunctive mood, the verb form often differs from the indicative mood, and subject-verb agreement rules may be altered.
For example, “I wish I were taller” uses “were” instead of “was.”
Why is subject-verb agreement so important?
Subject-verb agreement is crucial for clear and effective communication. It ensures that your sentences are grammatically correct and easy to understand.
Errors in subject-verb agreement can lead to confusion and misinterpretation.
