Definition of Subject-Verb Agreement
Subject-verb agreement, also known as concord, is the grammatical rule stating that the verb in a sentence must agree in number (singular or plural) and person (first, second, or third) with its subject. In simpler terms, if the subject is singular, the verb must be singular; if the subject is plural, the verb must be plural. This ensures that the sentence is grammatically correct and easy to understand.
The primary function of subject-verb agreement is to maintain grammatical consistency within a sentence. It helps to clearly establish the relationship between the subject and the action or state being described. In English, the most noticeable agreement occurs in the present tense, particularly with the third-person singular form, which often adds an “-s” or “-es” to the base form of the verb.
Understanding subject-verb agreement is essential in various contexts, including academic writing, professional communication, and everyday conversation. Correct usage enhances credibility and avoids potential misinterpretations. Therefore, a solid grasp of this concept is vital for effective communication in English.
Structural Breakdown
The basic structure of subject-verb agreement involves identifying the subject and then choosing the correct verb form that matches it. The subject is the noun or pronoun that performs the action or is being described. The verb is the action word or the state-of-being word.
In simple sentences, the subject usually precedes the verb. However, in more complex sentences, the subject and verb may be separated by phrases or clauses, which can make identifying the subject more challenging. It’s crucial to ignore these intervening elements and focus on the actual subject to determine the correct verb form.
Here’s a breakdown of the key structural elements:
- Subject: The noun or pronoun performing the action.
- Verb: The action word or state-of-being word.
- Agreement: Matching the verb form to the subject’s number and person.
For example:
- Singular: The cat sits on the mat.
- Plural: The cats sit on the mat.
In the first sentence, “cat” is singular, so the verb “sits” is used. In the second sentence, “cats” is plural, so the verb “sit” is used.
Types and Categories of Subject-Verb Agreement
Subject-verb agreement can be categorized based on the type of subject involved. Understanding these categories helps in applying the correct agreement rules.
Singular Subjects
A singular subject refers to one person, place, thing, or idea. Singular subjects require singular verbs. In the present tense, singular verbs often end in “-s” or “-es” (except for “I” and “you”).
Example: The dog barks loudly.
Plural Subjects
A plural subject refers to more than one person, place, thing, or idea. Plural subjects require plural verbs. In the present tense, plural verbs usually do not end in “-s” or “-es”.
Example: The dogs bark loudly.
Compound Subjects
A compound subject consists of two or more subjects joined by a conjunction such as “and,” “or,” or “nor.” When subjects are joined by “and,” they usually take a plural verb. However, if the subjects refer to a single entity or idea, a singular verb is used.
Example: John and Mary are going to the party. (Plural)
Example: Macaroni and cheese is my favorite dish. (Singular – a single dish)
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. (Singular – teacher is closer)
Example: Neither the teacher nor the students are here. (Plural – students is closer)
Collective Nouns
Collective nouns refer to a group of people or things considered as a single unit (e.g., team, family, committee). Collective nouns can take either a singular or a plural verb, depending on whether the group is acting as a single unit or as individual members.
Example: The team is playing well. (Singular – acting as a unit)
Example: The team are arguing about the strategy. (Plural – individual members)
Indefinite Pronouns
Indefinite pronouns refer to nonspecific people or things. Some indefinite pronouns are always singular (e.g., everyone, someone, nobody, each, every), 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).
Example: Everyone is invited to the party. (Singular)
Example: Both are good choices. (Plural)
Example: Some of the cake is gone. (Singular)
Example: Some of the cookies are gone. (Plural)
Gerunds and Infinitives
Gerunds (verbs ending in “-ing” used as nouns) and infinitives (the base form of a verb preceded by “to”) usually take a singular verb when used as the subject of a sentence.
Example: Swimming is good exercise. (Gerund)
Example: To err is human. (Infinitive)

Usage Rules for Subject-Verb Agreement
Mastering subject-verb agreement requires understanding the specific rules that govern its application. These rules cover various sentence structures and subject types.
Basic Agreement Rule
The fundamental rule is that a singular subject takes a singular verb, and a plural subject takes a plural verb. This is the foundation of subject-verb agreement.
Example: The girl sings. (Singular)
Example: The girls sing. (Plural)
Intervening Phrases and Clauses
Phrases or clauses that come between the subject and verb do not affect the agreement. The verb must agree with the actual subject, not the words in the intervening phrase or clause.
Example: The box of chocolates is on the table. (The subject is “box,” not “chocolates.”)
Example: The students who study hard get good grades. (The subject is “students,” not “who.”)
Sentences Starting with “There” or “Here”
In sentences that begin with “there” or “here,” the subject follows the verb. The verb must agree with the subject that comes after it.
Example: There is a book on the shelf. (The subject is “book.”)
Example: There are books on the shelf. (The subject is “books.”)
Example: Here is your key. (The subject is “key.”)
Example: Here are your keys. (The subject is “keys.”)
Questions
In questions, the subject and verb are often inverted. Ensure the verb agrees with the subject, even when they are not in the typical subject-verb order.
Example: Is the cat sleeping? (Singular)
Example: Are the cats sleeping? (Plural)
Titles and Organizations
Titles of books, movies, and organizations are usually treated as singular, even if they contain plural words.
Example: “The Adventures of Tom Sawyer” is a classic novel.
Example: The United Nations is an international organization.
Units of Measurement
Units of measurement (e.g., time, money, distance) are generally treated as singular when considered as a single unit or amount.
Example: Five dollars is too much to pay for that.
Example: Ten miles
is a long distance to walk.
“Either/Or” and “Neither/Nor” Constructions
When subjects are joined by “either/or” or “neither/nor,” the verb agrees with the subject closest to it. This rule ensures clarity when dealing with multiple subjects.
Example: Either the students or the teacher is responsible. (Singular – teacher is closer)
Example: Neither the teacher nor the students are responsible. (Plural – students is closer)
Common Mistakes in Subject-Verb Agreement
Even with a solid understanding of the rules, mistakes in subject-verb agreement are common. Here are some frequent errors to watch out for:
- Ignoring Intervening Phrases: Forgetting that phrases between the subject and verb don’t affect agreement.
- Incorrectly Identifying the Subject: Failing to identify the true subject of the sentence, especially in complex sentences.
- Using the Wrong Verb Form with Collective Nouns: Not recognizing when a collective noun is acting as a unit versus individual members.
- Misunderstanding Indefinite Pronouns: Not knowing which indefinite pronouns are singular, plural, or variable.
- Overlooking “There” and “Here” Sentences: Forgetting that the subject follows the verb in sentences starting with “there” or “here.”
- Errors with Compound Subjects: Incorrectly using singular or plural verbs with compound subjects joined by “and,” “or,” or “nor.”
Being aware of these common pitfalls can help you avoid errors and improve the accuracy of your writing.

Advanced Topics in Subject-Verb Agreement
Beyond the basic rules, certain advanced topics can further refine your understanding of subject-verb agreement.
The 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.
Example: I suggest that he be on time. (Subjunctive – “be” is used instead of “is”)
Example: If I were you, I would study harder. (Subjunctive – “were” is used instead of “was”)
Words That Seem Plural But Are Singular
Some words look plural but are actually singular and require a singular verb. These include words like “news,” “mathematics,” “physics,” and “economics” when referring to them as a field of study.
Example: The news is very interesting tonight.
Example: Mathematics is a challenging subject.
Relative Clauses
In relative clauses (clauses introduced by relative pronouns like “who,” “which,” or “that”), the verb must agree with the noun or pronoun to which the relative pronoun refers.
Example: The student who studies hard succeeds. (Singular – “who” refers to “student”)
Example: The students who study hard succeed. (Plural – “who” refers to “students”)
Frequently Asked Questions
Q: How do I identify the subject in a complex sentence?
A: Look for the main noun or pronoun that performs the action or is being described. Ignore any intervening phrases or clauses. Break down the sentence into smaller parts if necessary.
Q: What if a collective noun refers to a mixed group of individuals?
A: If the collective noun is acting as a unit, use a singular verb. If the members are acting individually, use a plural verb. Context is key.
Q: How do I handle indefinite pronouns like “some,” “any,” or “none”?
A: Check the noun they refer to. If the noun is singular or uncountable, use a singular verb. If the noun is plural, use a plural verb.
Q: What about sentences that start with “there” or “here”?
A: The subject follows the verb in these sentences. Make sure the verb agrees with the subject that comes after it.
Q: Are titles of books and movies always singular?
A: Yes, titles of books, movies, and organizations are generally treated as singular, even if they contain plural words.
