Subject-Verb Agreement Rules, Intervening Phrases, and Compound Subjects

Key Takeaways Explain This Topic AI

A verb must agree in person and number with its grammatical subject, regardless of words, phrases, or clauses that intervene between them.

Prepositional phrases introduced by expressions like 'along with', 'as well as', 'in addition to', and 'together with' do not change a singular subject into a plural one.

Compound subjects connected by 'and' take a plural verb unless the items form a single recognized unit or refer to the same entity.

With disjunctive subjects connected by 'or', 'nor', 'either...or', or 'neither...nor', the verb agrees with the subject noun phrase closest to it (the rule of proximity).

Indefinite pronouns like 'each', 'every', 'everyone', 'neither', and 'either' are grammatically singular, whereas pronouns like 'both', 'few', and 'several' are plural.

Core Agreement Mechanics & Third-Person Variations

The foundational principle of English grammar governing subjects and verbs is simple: a verb must agree in person (first, second, third) and number (singular, plural) with its subject. In the present simple tense, this relationship presents a distinct morphological contrast that frequently challenges non-native English speakers. While English nouns typically add an -s or -es suffix to form their plural forms ( one student vs. two students ), third-person singular verbs in the present tense add an -s or -es suffix ( the student walks vs. the students walk ).

To master subject-verb agreement for the ACCUPLACER ESL Language Use test, you must identify the structural core of the sentence—the true subject—and ignore non-essential modifiers that create distance between the subject and its predicate.

Singular vs. Plural Verb Forms in Present and Past Tenses

Person / Number Present Simple ( to work ) Present Auxiliary ( to be ) Present Auxiliary ( to have ) Past Auxiliary ( to be )

  • First Person Singular ( I ) work am have was
  • Second Person Singular ( you ) work are have were
  • Third Person Singular ( he/she/it/noun ) works is has was
  • Plural ( we/you/they/nouns ) work are have were

Notice that in regular present tense verbs, only the third-person singular form carries the -s inflection. In the past tense, only the verb to be retains distinct singular ( was ) and plural ( were ) forms. All other standard verbs in the past simple tense retain a uniform shape regardless of subject number ( the student worked / the students worked ). Incorrect: The results of the laboratory analysis confirms our hypothesis.

Correct: The results of the laboratory analysis confirm our hypothesis.

In the incorrect sentence above, the writer allowed the singular noun analysis (the object of a preposition) to dictate the verb form. The actual subject is the plural noun results , which demands the plural verb confirm .
