Definition of Subject-Verb Agreement
Subject-verb agreement refers to the correspondence between a subject and its verb in terms of number. In simpler terms, a singular subject requires a singular verb, and a plural subject requires a plural verb. This grammatical rule ensures that sentences are clear, logical, and grammatically correct. Mastering subject-verb agreement is essential for effective communication, as it helps avoid confusion and ensures that your message is easily understood.
The concept of subject-verb agreement extends beyond simple sentences. It applies to complex sentences with multiple clauses, as well as sentences with unusual word order. Understanding the nuances of subject-verb agreement is crucial for writing clear and grammatically sound sentences in various contexts.
Structural Breakdown
The structure of a sentence plays a crucial role in identifying the subject and verb and ensuring they agree. Typically, the subject precedes the verb, but this order can be altered in questions or sentences beginning with certain adverbs. Identifying the simple subject (the main noun or pronoun performing the action) is the first step. Then, determine whether the subject is singular or plural. Finally, choose the verb form that agrees with the subject.
Consider the sentence, “The dog barks loudly.” Here, “dog” is the singular subject, and “barks” is the singular verb form. If the subject were plural, such as “The dogs bark loudly,” the verb would change to the plural form, “bark.” Recognizing these fundamental structural elements is key to mastering subject-verb agreement.
Basic Rules of Subject-Verb Agreement
The core principle of subject-verb agreement is straightforward: singular subjects take singular verbs, and plural subjects take plural verbs. However, the application of this rule can become complex due to various factors, such as compound subjects, collective nouns, and indefinite pronouns. Let’s explore the basic rules with examples.
Rule 1: Singular subjects take singular verbs. For example, “He runs every morning.” Here, “He” is a singular subject, and “runs” is a singular verb.
Rule 2: Plural subjects take plural verbs. For example, “They run every morning.” Here, “They” is a plural subject, and “run” is a plural verb.
Rule 3: Be mindful of subject-verb agreement with the verb “to be” in the present tense. “I am,” “He/She/It is,” “We/You/They are.”
Rule 4: Phrases or clauses that come between the subject and verb do not affect subject-verb agreement. Focus on the actual subject when determining the correct verb form.
Compound Subjects
A compound subject consists of two or more subjects joined by a conjunction. The verb form depends on the conjunction used and the nature of the subjects.
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. However, there are exceptions when the subjects refer to a single entity or idea.
Example 1: “John and Mary are going to the party.” Here, “John” and “Mary” are two distinct subjects joined by “and,” so the plural verb “are” is used.
Example 2: “Peanut butter and jelly is my favorite sandwich.” In this case, “peanut butter and jelly” is considered a single entity (a sandwich), so the singular verb “is” is used.
Subjects Joined by ‘or’ or ‘nor’
When subjects are joined by “or” or “nor,” the verb agrees with the subject closest to it. This rule is often referred to as the “proximity rule.”
Example 1: “Either the students or the teacher is responsible.” Here, “teacher” is closer to the verb, and it is singular, so the singular verb “is” is used.
Example 2: “Neither the teacher nor the students are responsible.” In this case, “students” is closer to the verb, and it is plural, so the plural verb “are” is used.
Collective Nouns
Collective nouns refer to a group of individuals but are often treated as a single unit. Examples of collective nouns include “team,” “family,” “committee,” and “audience.” The verb form depends on whether the collective noun is acting as a single unit or as individual members.
If the collective noun is acting as a single unit, use a singular verb. For example, “The team is playing well.”
If the collective noun is acting as individual members, use a plural verb. For example, “The team are arguing about their roles.”
Indefinite Pronouns
Indefinite pronouns refer to nonspecific persons or things. Some indefinite pronouns are always singular (e.g., “each,” “every,” “someone,” “anyone,” “nobody”), while others are always plural (e.g., “both,” “few,” “several,” “many”). Some can be either singular or plural, depending on the context (e.g., “some,” “any,” “none,” “all,” “most”).
Singular Indefinite Pronouns: “Each has a different opinion.” “Everyone is invited.”
Plural Indefinite Pronouns: “Both are correct.” “Many were present.”
Indefinite Pronouns That Can Be Singular or Plural: “Some of the cake is gone.” (singular because “cake” is uncountable) “Some of the cookies are gone.” (plural because “cookies” are countable)
Intervening Phrases
Phrases or clauses that come between the subject and the verb do not affect subject-verb agreement. The verb must agree with the actual subject, not with any noun or pronoun in the intervening phrase.
Example 1: “The box of chocolates is on the table.” The subject is “box,” which is singular, so the verb “is” is used, even though “chocolates” is plural.
Example 2: “The students in my class are very intelligent.” The subject is “students,” which is plural, so the verb “are” is used, even though “class” is singular.
Inverted Sentences
In inverted sentences, the verb comes before the subject. This often occurs in questions or sentences that begin with adverbs like “here” or “there.” Identifying the subject in inverted sentences is crucial for correct subject-verb agreement.
Example 1: “Is John coming to the party?” The subject is “John,” which is singular, so the singular verb “is” is used.
Example 2: “There are many reasons to be happy.” The subject is “reasons,” which is plural, so the plural verb “are” is used.
Linking Verbs
Linking verbs connect the subject to a noun or adjective that describes or identifies the subject. The most common linking verb is “to be” (is, are, was, were, am, been, being). Subject-verb agreement with linking verbs is straightforward: the verb must agree with the subject.
Example 1: “My favorite fruit is apples.” The subject is “fruit,” which is singular, so the singular verb “is” is used.
Example 2: “My favorite fruits are apples and bananas.” The subject is “fruits,” which is plural, so the plural verb “are” is used.
Expressions of Quantity
Expressions of quantity, such as “half of,” “a third of,” or “a percentage of,” can be singular or plural depending on the noun they refer to. If the noun is uncountable, use a singular verb. If the noun is countable, use a plural verb.
Example 1: “Half of the water is gone.” “Water” is uncountable, so the singular verb “is” is used.
Example 2: “Half of the apples are rotten.” “Apples” are countable, so the plural verb “are” is used.
Titles and Organizations
Titles of books, movies, and organizations are usually treated as singular, even if they contain plural nouns. The verb should agree with the title as a whole, not with the individual words within the title.
Example 1: “The Adventures of Tom Sawyer is a classic novel.”
Example 2: “Microsoft is a multinational corporation.”
Relative Clauses
In relative clauses (clauses that begin with “who,” “which,” or “that”), the verb must agree with the noun or pronoun that the relative pronoun refers to (the antecedent).
Example 1: “The student who studies hard will succeed.” “Who” refers to “student,” which is singular, so the singular verb “studies” is used.
Example 2: “The students who study hard will succeed.” “Who” refers to “students,” which is plural, so the plural verb “study” is used.

These include the use of collective nouns, indefinite pronouns, and inverted sentences, as discussed earlier. Additionally, certain expressions of quantity and titles of works can also present challenges.
Exception 1: When a phrase expressing a unit of measurement or time is considered as a whole, it takes a singular verb. For example, “Five miles is a long distance to walk.”
Exception 2: Some nouns that appear plural in form are actually singular in meaning and take a singular verb. For example, “News is often biased.” “Mathematics is my favorite subject.”

Advanced Topics
For advanced learners, understanding subject-verb agreement in more complex sentence structures is essential. This includes dealing with gerunds, infinitives, and sentences beginning with “there” or “here.”
Subject-Verb Agreement with Gerunds
A gerund is a verb form ending in “-ing” that functions as a noun. When a gerund is used as the subject of a sentence, it takes a singular verb.
Example: “Swimming is good exercise.”
Subject-Verb Agreement with Infinitives
An infinitive is the base form of a verb preceded by “to.” When an infinitive phrase functions as the subject of a sentence, it takes a singular verb.
Example: “To learn a new language is challenging but rewarding.”
Subject-Verb Agreement with “There” and “Here”
When a sentence begins with “there” or “here,” the subject follows the verb. Be sure to identify the actual subject to ensure correct agreement.
Example 1: “There is a book on the table.” (singular subject “book”)
Example 2: “There are several books on the table.” (plural subject “books”)
Example 3: “Here is your key.” (singular subject “key”)
Example 4: “Here are your keys.” (plural subject “keys”)
Frequently Asked Questions
This section addresses common questions about subject-verb agreement.
Q1: What is subject-verb agreement?
A: Subject-verb agreement is the grammatical rule that the verb in a sentence must agree in number (singular or plural) with its subject. This ensures that the sentence is grammatically correct
and clear.
Q2: How do I identify the subject in a sentence?
A: The subject is the noun or pronoun that performs the action of the verb. In simple sentences, the subject usually comes before the verb. In more complex sentences, you may need to identify the main noun or pronoun that the verb refers to.
Q3: What if there is a phrase between the subject and the verb?
A: Phrases between the subject and verb do not affect subject-verb agreement. Focus on the actual subject to determine the correct verb form. For example, in the sentence “The box of chocolates is on the table,” the subject is “box,” not “chocolates.”
Q4: What about compound subjects?
A: Compound subjects joined by “and” usually take a plural verb. However, if the subjects refer to a single entity or idea, use a singular verb. Subjects joined by “or” or “nor” take a verb that agrees with the subject closest to it.
Q5: How do I handle collective nouns?
A: Collective nouns can be singular or plural, depending on whether they are acting as a single unit or as individual members. If the collective noun is acting as a single unit, use a singular verb. If it is acting as individual members, use a plural verb.
Q6: What are some common mistakes to avoid?
A: Common mistakes include incorrect agreement with intervening phrases, compound subjects, collective nouns, and indefinite pronouns. Also, be careful with inverted sentences where the subject follows the verb.
