Usage - Subject-Verb Agreement 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 present tenses, nouns and verbs form plurals in opposite ways:
nouns ADD an s to the singular form, BUT verbs REMOVE an s from the singular form.
Here are nine subject-verb agreement rules.
- A phrase or clause between subject and verb does not change the number of the
subject.
Examples:
- Indefinite pronouns as subjects
• Singular indefinite pronoun subjects take singular verbs.
• Plural indefinite pronoun subjects take plural verbs.
PLURAL: several, few, both, many
• Some indefinite pronouns may be either singular or plural:
with uncountable, use singular; with countable, use plural.
EITHER SINGULAR OR PLURAL: some, any, none, all, most
Sugar is uncountable; therefore, the sentence has a singular verb.
Marbles are countable; therefore, the sentence has a plural verb.
- Compound subjects joined by and are always plural.
- With compound subjects joined by or/nor, the verb agrees with the subject nearer
to it.
In the above example, the plural verb are agrees with the nearer subject actors.
In this example, the singular verb is agrees with the nearer subject director.
- Inverted Subjects must agree with the verb.
- Collective Nouns (group, jury, crowd, team, etc.) may be singular or plural,
depending on meaning.
In this example, the jury is acting as one unit; therefore, the verb is singular.
In this example, the jury members are acting as twelve individuals; therefore, the verb is plural.
- Titles of single entities (books, organizations, countries, etc.) are always singular.
