ACT English: Fix Pronoun-Antecedent Errors With This One Simple Rule

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 the antecedent is plural, the pronoun must be plural. Example: "Each student completed their homework" is wrong because "each student" is singular, so the pronoun should be "his or her" or the sentence should be rewritten as "All students completed their homework." This one rule covers 85% of pronoun errors on the ACT, so memorize it and apply it mechanically.

Another example: "The team celebrated because they won the championship." This is correct because "team" is treated as a plural entity (the members of the team). But "The team is known for its strong defense" uses "its" (singular) because we're treating "team" as a single unit. Context determines whether a collective noun is singular or plural.

Trap 1: Using "they/their" for a singular antecedent. "A student should bring their books" is common but grammatically wrong; it should be "A student should bring 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 Sarah or Maria won. Fix by clarifying: "Sarah told Maria that Maria had won the award." Trap 3: Pronoun too far from antecedent. A pronoun must be close enough to its antecedent to be clearly understood. Trap 4: Wrong pronoun case. "Between you and I" is wrong; it should be "between you and me" because "me" is the object of the 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 the answer choices.

Sentence 1: "Every employee must submit their timesheet by Friday." Error: Singular antecedent with plural pronoun. Fix: "Every employee must submit his or her timesheet by Friday" or "All employees must submit their timesheets by Friday." Sentence 2: "The committee made their decision and announced it yesterday." Error: Collective noun; depends on usage. This is acceptable if treating the committee as individuals. Sentence 3: "Between him and I, this plan won't work." Error: Wrong pronoun case. Fix: "Between him and me, this plan won't work." Sentence 4: "Maria and Jessica brought her book to class." Error: Unclear antecedent (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, so use "its." Fix: "The data shows its trend over time."

Now find five pronoun questions from a practice test and solve them by identifying the antecedent first. Mark the antecedent and verify the pronoun matches. By the fifth question, pronoun agreement will feel automatic.

Pronoun errors appear on nearly every ACT English test and are consistently tested. Because the rule is learnable and mechanical, this is one of the easiest skills to master. Learning to spot pronoun-antecedent mismatches picks up 1-2 points on the English section because these errors are so common and the fix is so straightforward.
