Agreement

Agreement in Language Definition

To fully grasp the concept of agreement, begin with the definition.

Another term for the concept of agreement is concord. Both these terms imply the harmony created between two words or parts of speech (and the disharmony when they are not in agreement). For example, these books illustrates how the number of the demonstrative (these) must harmonize with the number of the noun (books). Without this agreement, we’d have a phrase like “this books” or “these book” which is clearly incorrect.

Agreement is an instance of a broader grammatical term called inflection.

In English, the grammatical categories that are most often altered to “agree” are person and number.

• Person (Example: I am vs. she is)

• Number (Example: The truck digs vs. the trucks dig)

In English, one can say, "I talk a lot," but when the subject shifts from first person (I) to third person (he/ she), the verb must change slightly, too; "he talks a lot." Notice the addition of the ‘s’ to the verb. We call this phenomenon subject-verb agreement, and it’s prevalent in English.

Subject-verb Agreement

Subject-verb agreement refers to matching a verb to its subject in number, person, and, when necessary, gender.

English doesn’t use grammatical gender like other languages. For example, Spanish uses grammatical gender, so Spanish verbs must agree with the gender of the subject.

Pronouns are some of the few words that are gendered in English.

• He (male)

• She (female)

Like gender, person as a grammatical category isn’t a common concern for agreement in modern English. The verb be (am, are, is) is the exception and changes with person.

The verb be changes with person; whether first, second, or third person. Because gender and person very seldom affect Modern English, the vast majority of subject-verb agreement depends on number.

Subject-verb Agreement Rules

There are a few rules that govern subject-verb agreement. While native English speakers rarely think about these rules expressly, it’s helpful to understand them to better understand how the language functions.

Basic Subject-verb Agreement Rule

Singular subjects receive singular verbs, and plural subjects receive plural verbs.

Agreement Rules for Compound Subjects

1. Compound subjects that use or or nor can take either plural or singular verbs.

2. Compound subjects that use the word “and” require plural verbs.

Agreement Rules for Plural Subjects

1. Plural-form subjects are typically singular when used as titles, so they take a singular verb.

2. Collective nouns can be singular or plural, depending on how they are understood in context. A word like team is considered singular—even though it refers to a number of people or things—and thus uses a singular verb. On the other hand, collective nouns like party members are considered plural and thus take a plural verb.

3. The word they (and its possessive form their) can be either singular or plural. It might refer to a group of people or a single person. Read the context for information about whether the subject is singular or plural.

Agreement Rule for Indefinite Pronouns

Indefinite pronouns like anyone, everywhere, and nothing are singular and take a singular verb.

Agreement Rule for Gerunds

Gerunds typically function as singular nouns and thus take a singular verb.

Agreement Rule for “A Pair”

A pair of something is a singular noun and takes a singular verb. For example, pair in the following example is the singular subject:

Agreement Rule for Time, etc.

Time, money, and measurements are considered a singular unit, so use a singular verb.

Subject-verb Agreement Examples in Literature

As subject-verb agreement is the primary concern for English speakers, the following examples illustrate a few of the rules of subject-verb agreement as seen in literature.

This sentence has two examples of collective nouns; one is singular (crowd), and the other is plural (people). The word crowd is treated as a singular noun and so is connected to the singular verb was. Following the semicolon is another collective noun, people, but in this case, the collective noun functions as a plural noun, and so the verb is plural—were.

Subject-verb agreement rule #4 explains the way Lewis worded this sentence. Everyone is an indefinite pronoun, which is treated as a singular noun. This is why the verb to know is conjugated with a singular noun—knows.

Types of Agreement in Linguistics

There are two types of agreement in linguistics: formal agreement and notional agreement.

Because of the rules mentioned above, an English speaker could not say “I is” or “you is” because this would contradict the laws of subject-verb agreement. The speaker must instead say, “I am” or “you are.” This is an example of formal agreement. A formal agreement is based on the grammatical category of the words involved.

The words “I am” agree with one another because I is a singular personal pronoun, and am is the first-person singular form of the verb to be. Their agreement is a formal agreement, not a notional agreement.

As opposed to formal agreement, notional agreement is formed based on meaning rather than grammatical category. The subject-verb agreement rule that states collective nouns can be singular or plural, depending on how they are understood in context, is based on notional agreement.

For example, The United States is often referred to as a single unit and is thus paired with singular verbs. E.g., “The United States is responsible for the majority of oil consumption in the world.” In a different context, the United States might be understood as a collection of multiple states, and so a plural noun. You might hear someone use the term “these united states” which is a plural noun (notice the plural determiner these).
