Subject-Verb Agreement - My English Path

What is subject-verb agreement?

In a sentence, the form of verb has to match the subject. This matching or agreement is related to number (singular or plural) and person (1st, 2nd, or 3rd).

In the following sentence, the subject movie is 3rd person singular, so we add s to the verb in the present simple.

The movie starts at 10 pm.

While in this sentence, the subject movies is 3rd person plural, so we use the verb without s.

Movies at this cinema usually start at 11 pm.

Rules of subject-verb agreement

– Add s to the present simple tense verb if the subject is 3rd person singular (he, she, it) in affirmative sentences.

Modals

There is / There are / There was / There were

The structure that has there + be is called “expletive.” It does not have a meaning on its own. It introduces the idea that something is in a particular place. The form of the sentence is:

There + be (is, are, was, were, has/have/had been) + subject + place.

(The expression of place can be deleted if it is understood from the context.)

The subject-verb agreement in this structure is between the verb be and the subject following it: with singular nouns use is / was / has been, and with plural subjects use are / were / have been.

There is / was / has been one bird in the cage. (singular subject)
There are / were / have been two birds in the cage. (plural subject)

Quantifiers

Quantifiers are used to modify nouns. Some expressions of quantity are used with count nouns only, some are used with noncount nouns only, while a few of these expressions can be used with both.

Find out more about quantifiers and how we use them with count and noncount nouns here.

The verb is determined by the noun following the quantifier. Singular verbs are used with singular and noncount nouns, while plural verbs are used with plural nouns

Some of the discussion was informative. (singular noun after some of)
Some of the discussions were informative. (plural noun after some of)

Collective nouns

A collective noun is a noun that denotes a group of members. Collective nouns can take plural verbs or singular verbs depending on the speaker’s view of the noun. In other words, if you look at the noun as a single impersonal unit, use a singular verb.
