Pronoun-antecedent agreement
Pronoun-antecedent agreement is the grammar rule that a pronoun must match the noun it refers to (its antecedent) in number, person, and gender. A singular antecedent takes a singular pronoun; a plural antecedent takes a plural pronoun.
A pronoun stands in for a noun, and the noun it replaces is called its antecedent. Pronoun-antecedent agreement requires the pronoun to match that antecedent in number (singular or plural), person (first, second, or third), and gender. "The students turned in their essays" agrees; "Each student turned in their essay" is the kind of sentence standardized tests love to scrutinize, because each is grammatically singular.
Most errors involve number. Indefinite pronouns such as each, everyone, anybody, neither, and either are singular and traditionally take singular pronouns: "Everyone must bring his or her ID." Collective nouns like team, committee, and company are usually treated as singular units: "The committee announced its decision," not their decision. With compound antecedents, and creates a plural ("Jack and Jill lost their pail"), while or and nor make the pronoun agree with the nearer antecedent.
Clarity matters as much as matching. A pronoun with two possible antecedents — "When Maria met Ana, she was late" — creates an ambiguous reference that formal writing (and test writers) treat as an error. The fix is usually to repeat the noun or restructure the sentence.
Pronoun-antecedent agreement is a core tested skill on the ACT English section. Expect questions that hinge on singular indefinite pronouns, collective nouns, and vague pronoun references, where the correct answer replaces a mismatched or ambiguous pronoun with one that clearly agrees with its antecedent.
