Subject - Verb Agreement

Although you are probably already
familiar with basic subject-verb agreement, this chapter begins with a quick
review of basic agreement rules.
~Subjects and verbs
must AGREE with one another in number
(singular or plural). Thus, if a
subject is singular, its verb must also be singular; if a subject is plural, its
verb must also be plural.
~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.
1)These agreement rules do not apply to
verbs used in the simple past tense without any helping verbs.
2)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.
3)The agreement rules do not apply to has-have when used as the
SECOND helping verb in a pair.
4)They do NOT apply to any other helping
verbs, such as can, could, shall, should,
may, might, will, would, must.
5)The subject-verb agreement rules apply
to all personal pronouns except I and you,
which, although SINGULAR, require PLURAL forms of verbs.
