Subject verb agreement. Although you are probably already familiar with basic subject-verb agreement, this lesson begins with a quick review of basic agreement rules.
Although you are probably already familiar with basic subject-verb agreement, this lesson begins with a quick review of basic agreement rules.
In the present tense, nouns and verbs form plurals in opposite ways: nouns ADD an s to the singular form; verbs REMOVE the s from the singular form.
These agreement rules do not apply to verbs used in the simple past tense without any helping verbs.
The girltalked to me.
The girls talked to me.
The agreement rules do, however, apply to the following helping verbs when they are used with a main verb: is-are, was-were, has-have, does-do.
The agreement rules do not apply to has-have when used as the SECOND helping verb in a pair.
They do NOT apply to any other helping verbs, such as can, could, shall, should, may, might, will, would, must.
The subject-verb agreement rules apply to all personal pronouns except I and you, which, although SINGULAR, require PLURAL forms of verbs.

What if one part of the compound subject is singular and the other part is plural?
