Definition of Subject-Verb Agreement
Subject-verb agreement refers to the correspondence between the subject and verb in a sentence, ensuring they match in number (singular or plural). This agreement is crucial for grammatical correctness and clarity.
The basic principle is straightforward: singular subjects take singular verbs, and plural subjects take plural verbs. However, various factors can complicate this simple rule, including compound subjects, collective nouns, and indefinite pronouns.
In essence, subject-verb agreement ensures that the verb form accurately reflects the subject performing the action. Without proper agreement, sentences can sound awkward, confusing, or even grammatically incorrect.
This guide will explore the intricacies of subject-verb agreement, providing detailed explanations, examples, and exercises to help you master this essential aspect of English grammar.
Classification
Subject-verb agreement falls under the broader category of grammatical agreement, which also includes noun-pronoun agreement and adjective-noun agreement. Grammatical agreement ensures that different parts of a sentence are consistent with each other in terms of number, gender, and case, where applicable.
Subject-verb agreement specifically focuses on the relationship between the subject and the verb.
Function
The primary function of subject-verb agreement is to maintain grammatical correctness and clarity in sentences. It helps readers or listeners understand who or what is performing the action described by the verb.
Correct subject-verb agreement enhances the overall flow and readability of written and spoken English.
Contexts
Subject-verb agreement is essential in all forms of English communication, including formal writing (e.g., academic papers, business reports), informal writing (e.g., emails, blog posts), and spoken English (e.g., conversations, presentations). Paying attention to subject-verb agreement is particularly important in situations where precision and professionalism are required.
Structural Breakdown
Understanding the structure of sentences is crucial for mastering subject-verb agreement. The subject is the noun or pronoun that performs the action or is being described.
The verb is the word that expresses the action or state of being. Identifying the subject and verb correctly is the first step in ensuring proper agreement.
The basic sentence structure in English is Subject-Verb-Object (SVO). However, sentences can be more complex, with modifiers, phrases, and clauses that can obscure the subject and verb.
It is important to identify the core subject and verb to ensure they agree in number.
Identifying the Subject
The subject of a sentence is the noun or pronoun that performs the action or is being described. It usually appears before the verb, but not always.
In questions, the subject may appear after the verb or between the auxiliary verb and the main verb. Phrases and clauses can also function as subjects.
For example, in the sentence “The cat sleeps on the mat,” the subject is “The cat.” In the question “Does she like ice cream?” the subject is “she.” In the sentence “Running every day is good for your health,” the subject is the gerund phrase “Running every day.”
Identifying the Verb
The verb expresses the action or state of being. It can be a single word or a verb phrase consisting of an auxiliary verb and a main verb.
The verb must agree in number with the subject of the sentence.
For example, in the sentence “He sings beautifully,” the verb is “sings.” In the sentence “They are playing soccer,” the verb phrase is “are playing.” In the sentence “She has been working hard,” the verb phrase is “has been working.”
Basic Agreement Rules
The fundamental rule of subject-verb agreement is that singular subjects take singular verbs, and plural subjects take plural verbs. This rule applies to all tenses, but it is most noticeable in the present tense.
For example:
* Singular: The dog barks.
* Plural: The dogs bark.
Types and Categories
Subject-verb agreement can be categorized based on different types of subjects and verbs. Understanding these categories is crucial for applying the rules correctly.
Singular and Plural Nouns
Singular nouns refer to one person, place, thing, or idea. Plural nouns refer to more than one.
The verb must agree with the number of the noun.
Examples:
* Singular: The book is on the table.
* Plural: The books are on the table.
Compound Subjects
A compound subject consists of two or more nouns or pronouns joined by a conjunction such as “and,” “or,” or “nor.” The verb agreement depends on the conjunction used.
* And: When subjects are joined by “and,” they usually take a plural verb.
* Example: John and Mary are going to the party.
* Or/Nor: When subjects are joined by “or” or “nor,” the verb agrees with the subject closest to it.
* Example: Neither the students nor the teacher is here.
* Example: Neither the teacher nor the students are here.
Collective Nouns
Collective nouns refer to a group of people or things. They 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, the collective noun takes a singular verb.
* Example: The team is playing well.
* If the group members are acting individually, the collective noun takes a plural verb.
* Example: The team are arguing about the strategy.
Indefinite Pronouns
Indefinite pronouns refer to unspecified persons or things. Some indefinite pronouns are always singular (e.g., everyone, someone, nobody), some are always plural (e.g., both, few, several), and some can be singular or plural depending on the context (e.g., some, any, none, all, most).
* Always Singular: Each, everyone, someone, somebody, no one, nobody, anyone, anybody, everything, something, nothing, anything
* Example: Everyone is invited to the party.
* Always Plural: Both, few, several, many
* Example: Both are correct.
* Singular or Plural: Some, any, none, all, most
* Example: Some of the cake is gone. (singular)
* Example: Some of the cookies are gone. (plural)
Relative Clauses
In relative clauses, the verb must agree with the noun or pronoun that the relative pronoun (who, which, that) refers to.
Example: The book that is on the table is mine.

Usage Rules
Understanding the rules of subject-verb agreement is essential for accurate and effective communication. These rules cover various scenarios, including exceptions and special cases.
Intervening Phrases
Phrases that come between the subject and the verb do not affect subject-verb agreement. It is important to identify the actual subject and make the verb agree with it, ignoring any intervening phrases.
Example: The box of chocolates is on the table. (The subject is “box,” not “chocolates.”)
Sentences Starting with “There” or “Here”
In sentences starting with “there” or “here,” the subject comes after the verb. The verb must agree with the actual subject that follows it.
Example: There is a book on the shelf.
Example: Here are the keys.
Titles of Works
The titles of books, movies, and songs are treated as singular, even if they contain plural nouns.
Example: “The Adventures of Tom Sawyer” is a classic novel.
Units of Measurement
Units of measurement (e.g., time, money, distance) are usually treated as singular when they refer to a single quantity or amount.
Example: Five dollars is too much to pay for that.
“Every” and “Each”
When “every” or “each” precedes a compound subject, the verb is singular.
Example: Every student and teacher is required to attend.
Common Mistakes
Subject-verb agreement is a common source of errors for English language learners. Recognizing and avoiding these mistakes is crucial for improving your grammar skills.
Mistake 1: Ignoring Intervening Phrases

Inverted sentences are sentences where the verb comes before the subject. Subject-verb agreement still applies in these sentences.
Example: Never have I seen such a beautiful sight.
Words Expressing Quantity
Words expressing quantity, such as “majority,” “minority,” or “percentage,” can be singular or plural depending on the noun they refer to.
Example: The majority of students are in favor of the proposal.
Example: The majority of the budget is allocated to education.
Frequently Asked Questions
Here are some frequently asked questions about subject-verb agreement.
- What is subject-verb agreement?
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 clarity and correctness in writing and speaking.
- How do I identify the subject in a sentence?
The subject is the noun or pronoun that performs the action or is being described. It usually comes before the verb, but not
always. Look for the main noun or pronoun that the sentence is about.
- What are some common mistakes in subject-verb agreement?
Common mistakes include ignoring intervening phrases, incorrect agreement with compound subjects, misunderstanding collective nouns, using plural verbs with singular indefinite pronouns, and confusing “there is/are.”
- How do I handle collective nouns?
