ACT English Pronoun Agreement: Match Pronouns to Antecedents Perfectly

A pronoun must match the noun it replaces (its antecedent) in number and gender. If the antecedent is singular, the pronoun must be singular. If plural, the pronoun must be plural. Example: "Each student completed their homework" is wrong because "each student" is singular, so use "his or her" instead. Fix: "All students completed their homework" or "Each student completed his or her homework." This one rule covers 85% of pronoun errors on the ACT, so memorize it and apply it mechanically every time you spot a pronoun.

Context matters for collective nouns: "The team celebrated because they won" treats the team as individuals (plural pronoun). But "The team is known for its defense" treats the team as a single unit (singular pronoun). Let context guide whether the collective noun is singular or plural.

Trap 1: Using "they/their" for a singular antecedent. "A student should bring their books" is common speech but grammatically wrong. Use "his or her books" or rewrite as "Students should bring their books." Trap 2: Unclear antecedent. "Sarah told Maria that she had won the award" could mean either won. Fix by clarifying: "Sarah told Maria that Maria had won." Trap 3: Pronoun too far from antecedent. A pronoun must be close enough to be clearly understood. Trap 4: Wrong pronoun case. "Between you and I" is wrong; use "me" (object of preposition). These four mistakes account for most pronoun errors on the test.

When you see a pronoun, immediately identify its antecedent and verify agreement. If you can't clearly identify the antecedent, the sentence needs revision. This habit prevents errors before you see answer choices.

Sentence 1: "Every employee must submit their timesheet." Error: Singular antecedent with plural pronoun. Fix: "Every employee must submit his or her timesheet" or "All employees must submit their timesheets." Sentence 2: "The committee made their decision and announced it." Acceptable if treating members individually; singular "its" if treating as unit. Sentence 3: "Between him and I, this plan won't work." Error: Wrong case. Fix: "Between him and me, this plan won't work." Sentence 4: "Maria and Jessica brought her book to class." Error: Unclear whose book. Fix: "Maria and Jessica brought their books to class." Sentence 5: "The data shows their trend over time." Error: "Data" is singular in American English. Fix: "The data shows its trend." Sentence 6: "Everyone should bring their own supplies." Error: Singular antecedent with plural pronoun. Fix: "Everyone should bring his or her own supplies."
