What is subject-verb agreement?

This section introduces subject-verb agreement and explains the relationship between singular and plural subjects and verbs.

The rule

You probably know the rule already, but let's take a quick look at it.

A verb must agree with its subject.

A singular verb must have a singular subject.

A plural verb must have a plural subject.


Subjects can be:

  • nouns (e.g. book, technique, people, happiness).
  • pronouns (e.g. it, theirs, each, all).
  • longer phrases built up around a head noun (e.g. the interesting book that I bought yesterday; these techniques; people in Melbourne).
  • longer phrases built up after a head pronoun (e.g. each person who came; all of the ideas presented).
