Subject-Verb Agreement Rules

To ensure subject-verb agreement, there are 13 rules to follow.

Rule 1: Plural Subjects Joined by "and"

Two or more subjects joined by "and" are considered plural and require a verb form without an "s."

Rule 2: Singular Subjects Modified by "each" or "every"

If a subject is modified by the words "each" or "every", it is singular and will take a verb form that ends in "s."

Rule 3: Plural Subjects Joined by "or", "nor", or "but"

If plural subjects are joined by "or", "nor", or "but", the verb must agree with the subject closest to it.

Rule 4: Indefinite Pronouns

Indefinite pronouns are usually singular and take a verb form that ends in "s."
A list of indefinite pronouns can be found at the end of the handout.

Rule 5: Subjects in Prepositional or Verbal Phrases

The subject of a verb is never in a prepositional or verbal phrase.
To find the proper subject, isolate the phrase.

Rule 6: Indefinite Pronouns and Nouns Depending on the Object of the Prepositional Phrase

Some indefinite pronouns and nouns can be singular or plural depending on the object of the prepositional phrase.
These words are often about number or amount, such as "all", "half", "some", "none", "most", "part", etc.

Rule 7: Collective Nouns

When a collective noun, such as "family", "group", "committee", or "class", is the subject, the verb will end in "s."

Rule 8: Singular Nouns Ending in "s"

Some nouns, such as "economics", "mumps", "measles", or "news", end in "s" but are considered singular.

Third Person Singular Verbs

In the third person singular, an "s" is added to the verb form.
This rule applies to every singular third person verb in the English language.
