Subject-verb agreement is a fundamental aspect of English grammar that ensures clarity and coherence in writing and speech. It dictates that a verb must agree in number (singular or plural) with its subject.
While the concept seems straightforward, its application can become complex due to various exceptions, compound subjects, and intervening phrases. Understanding and mastering subject-verb agreement is crucial for effective communication, as errors in this area can lead to misinterpretations and weaken the credibility of your writing.
This comprehensive guide is designed for English language learners of all levels, from beginners seeking a solid foundation to advanced speakers aiming to refine their grammar skills. By exploring the rules, exceptions, and common mistakes, you will gain the confidence to use correct subject-verb agreement in any context.

Definition of Subject-Verb Agreement
Subject-verb agreement, at its core, means that the verb in a sentence must match the number of its subject. If the subject is singular, the verb must be singular.
If the subject is plural, the verb must be plural. This agreement ensures that the sentence is grammatically correct and easy to understand.
It’s a foundational element of English syntax, influencing how sentences are constructed and interpreted.
In simpler terms, think of it as a matching game: the subject and verb must correspond in quantity. A singular subject takes a singular verb, while a plural subject takes a plural verb.
For example, “The dog barks” (singular) versus “The dogs bark” (plural). This principle applies across various sentence structures and tenses.
The concept extends beyond simple present tense. It also affects auxiliary verbs (helping verbs) like is, are, was, were, has, have, and do, does, did. Correct subject-verb agreement is essential for clear, effective communication, preventing confusion and ensuring that your intended meaning is accurately conveyed.
Structural Breakdown
Understanding the structure of subject-verb agreement involves identifying the subject and verb in a sentence and then ensuring they agree in number. This process can be broken down into several key steps.
Identifying the Subject
The subject of a sentence is the noun or pronoun that performs the action or is being described. It typically appears before the verb, but not always. To find the subject, ask yourself “Who or what is performing the action?” or “Who or what is being described?”
For example, in the sentence “The cat sleeps on the mat,” the subject is “The cat.” In the sentence “They are playing soccer,” the subject is “They.”
Identifying the Verb
The verb is the action word or state of being in a sentence. It describes what the subject is doing or being. Identifying the verb is crucial for determining the correct form to use.
In the sentence “The bird sings beautifully,” the verb is “sings.” In the sentence “We are happy,” the verb is “are.”
Determining Number (Singular or Plural)
Once you’ve identified the subject and verb, determine whether each is singular or plural. Singular subjects refer to one person, place, thing, or idea.
Plural subjects refer to more than one.
For example, “dog” is singular, while “dogs” is plural. “He” is singular, while “they” is plural.
Applying the Agreement Rule
The fundamental rule is: Singular subjects take singular verbs, and plural subjects take plural verbs.
In the present tense, singular verbs often end in “-s” (e.g., he sings, she walks, it eats), while plural verbs do not (e.g., they sing, we walk, you eat). However, the verb “to be” (is, are, was, were) follows a slightly different pattern.
Types of Subject-Verb Agreement
Subject-verb agreement can manifest in various forms, depending on the type of subject and verb used. Here are some common types:
Simple Subject-Verb Agreement
This is the most basic form, where a singular subject takes a singular verb, and a plural subject takes a plural verb.
Examples: “The student studies” (singular) vs. “The students study” (plural).
Compound Subjects
A compound subject consists of two or more subjects joined by a conjunction such as “and,” “or,” or “nor.”
- Subjects joined by “and” usually take a plural verb. Example: “John and Mary are going to the party.”
- Subjects joined by “or” or “nor” take a verb that agrees with the subject closest to the verb. Example: “Neither the students nor the teacher is happy with the test results.”
Collective Nouns
Collective nouns refer to a group of individuals but are treated as a single unit. Examples include team, family, committee, and group.
- If the group is acting as a single unit, use a singular verb. Example: “The team is playing well.”
- If the members of the group are acting individually, use a plural verb. Example: “The family are arguing about the vacation plans.” (less common, more often “The family is arguing…”)
Indefinite Pronouns
Indefinite pronouns refer to nonspecific persons or things. Some are always singular (each, everyone, someone, nobody), some are always plural (both, few, several), and some can be singular or plural depending on the context (some, any, none, all, most).
- Singular indefinite pronouns take singular verbs. Example: “Everyone is invited to the ceremony.”
- Plural indefinite pronouns take plural verbs. Example: “Both are excellent choices.”
- For those that can be either, look at the noun they refer to. Example: “Some of the pie is gone” (singular) vs. “Some of the cookies are gone” (plural).
Intervening Phrases
Intervening phrases are groups of words that come between the subject and the verb. These phrases can sometimes obscure the true subject and lead to errors in agreement.
Example: “The box of chocolates is on the table.” The subject is “box,” not “chocolates.” The verb should agree with “box” (singular).

Usage Rules
Several rules govern the proper use of subject-verb agreement. These rules ensure that sentences are grammatically correct and clear.
Rule 1: Basic Agreement
A singular subject takes a singular verb, and a plural subject takes a plural verb. This is the fundamental rule of subject-verb agreement.
Example: “The cat sleeps” (singular) vs. “The cats sleep” (plural).
Rule 2: Compound Subjects Joined by “And”
When two or more subjects are joined by “and,” they usually take a plural verb. This is because “and” creates a plural subject.
Example: “John and Mary are going to the party.”
Exception: If the compound subject refers to a single idea or entity, use a singular verb. Example: “Peanut butter and jelly is my favorite sandwich.”
Rule 3: Compound Subjects Joined by “Or” or “Nor”
When two or more subjects are joined by “or” or “nor,” the verb agrees with the subject closest to the verb.
Example: “Neither the students nor the teacher is happy with the test results.” In this case, “teacher” is closer to the verb, and it is singular, so the verb is singular.
Rule 4: Collective Nouns
Collective nouns can be singular or plural, 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. Example: “The team is playing well.”
If the members of the group are acting individually, use a plural verb. Example: “The family are arguing about the vacation plans.” (more common to say “The family is arguing…”)
Rule 5: Indefinite Pronouns
Some indefinite pronouns are always singular (each, everyone, someone, nobody), some are always plural (both, few, several), and some can be singular or plural depending on the context (some, any, none, all, most).
Singular indefinite pronouns take singular verbs. Example: “Everyone is invited to the ceremony.”
Plural indefinite pronouns take plural verbs. Example: “Both are excellent choices.”
For those that can be either, look at the noun they refer to. Example: “Some of the pie is gone” (singular) vs.
“Some of the cookies are gone” (plural).
Rule 6: Intervening Phrases
Intervening phrases do not affect subject-verb agreement. The verb must agree with the true subject, not the words in the intervening phrase.
Example: “The box of chocolates is on the table.” The subject is “box,” not “chocolates.” The verb should agree with “box” (singular).
Rule 7: “There is” and “There are”
When using “there is” or “there are,” the subject follows the verb. The verb must agree with the subject that follows it.
Example: “There is a book on the table” (singular) vs. “There are books on the table” (plural).
Rule 8: Subjects That Follow the Verb
In some sentences, the subject follows the verb. In these cases, the verb must still agree with the subject.
Example: “Standing outside were two men.” The subject is “two men,” which is plural, so the verb is “were.”
Common Mistakes
Subject-verb agreement errors are common, even among native English speakers. Here are some frequent mistakes and how to avoid them.
Mistake 1: Ignoring Intervening Phrases
Incorrect: “The list of items are on the table.”
Correct: “The list of items is on the table.”
The subject is “list,” not “items.” The verb must agree with “list,” which is singular.
Mistake 2: Incorrectly Using Compound Subjects
Incorrect: “John and Mary is going to the party.”
Correct: “John and Mary are going to the party.”
When two or more subjects are joined by “and,” they usually take a plural verb.
Mistake 3: Misunderstanding Collective Nouns
Incorrect: “The team are playing well.” (when referring to the team as a unit)
Correct: “The team is playing well.”
If the group is acting as a single unit, use a singular verb.
Mistake 4: Incorrectly Using Indefinite Pronouns
Incorrect: “Everyone are invited to the ceremony.”
Correct: “Everyone is invited to the ceremony.”
“Everyone” is a singular indefinite pronoun and takes a singular verb.
Mistake 5: Confusing “There is/are”
Incorrect: “There is books on the table.”
Correct: “There are books on the table.”
The verb must agree with the subject that follows it. In this case, the subject is “books,” which is plural.
Mistake 6: Forgetting to Account for Subjects Following the Verb
Incorrect: “Standing outside was two men.”
Correct: “Standing outside were two men.”
The subject, “two men,” is plural and requires the plural verb “were.”

Advanced Topics
Beyond the basic rules, certain advanced topics can further refine your understanding of subject-verb agreement.
Titles of Works
The titles of books, movies, and other works are treated as singular, even if they contain plural words.
Example: “The Lord of the Rings is a popular book series.”
Gerunds
A gerund (a verb form ending in “-ing” that functions as a noun) used as a subject takes a singular verb.
Example: “Swimming is good exercise.”
Sentences Beginning with “Here” or “There”
In sentences that begin with “here” or “there,” the subject follows the verb. Ensure the verb agrees with the subject that follows.
Example: “Here are the keys” vs. “There is a problem.”
Relative Clauses
In relative clauses (clauses introduced by relative pronouns like “who,” “which,” or “that”), the verb must agree with the noun or pronoun that the relative pronoun refers to.
Example: “He is one of the students who study hard.” (The verb “study” agrees with “students.”)
Words Expressing Quantity
Words like “percent,” “fraction,” “majority,” and “number” can be singular or plural depending on what they refer to.
Example: “Twenty percent of the students are absent.” (plural) vs. “Twenty percent of the budget is spent.” (singular)
