Overview

Pronoun-Antecedent Agreement questions test whether a pronoun matches its antecedent in number (singular/plural) and gender, whether the pronoun reference is clear and unambiguous, and whether the correct pronoun case and form is used. These questions appear under the Form, Structure, and Sense sub-domain. Students must identify the antecedent — the specific noun a pronoun refers to — and ensure the pronoun matches it precisely. Errors can involve number disagreement, vague reference, pronoun case confusion, or mid-passage pronoun shifts.

Key Points

1. Number Agreement

A pronoun must match its antecedent in number. If the antecedent is singular, the pronoun must be singular; if plural, the pronoun must be plural.

Antecedent TypeAntecedentCorrect PronounExample
Regular singularthe scientistshe / he / his / her”The scientist published her findings.”
Regular pluralthe scientiststhey / their / them”The scientists published their findings.”
Indefinite (singular)everyone, someone, each, either, neitherhe or she / his or her”Each student must submit his or her essay.”
Collective (singular)team, committee, audience, governmentit / its”The team celebrated its victory.”
Compound with “and”Maria and Juliathey / their”Maria and Julia submitted their reports.”
Compound with “or/nor”Maria or Juliashe / her”Either Maria or Julia will submit her report.”

2. Clear Pronoun Reference

A pronoun must have exactly one clear antecedent. If a pronoun could refer to two or more nouns, the sentence has an ambiguous reference error.

Wrong (ambiguous): “Maria told Julia that she was late.” (Who is late — Maria or Julia?) Correct: “Maria told Julia that Julia was late.” (Replace pronoun with specific noun.)

Wrong (missing antecedent): “In the article, they argue that climate change is accelerating.” (Who is “they”?) Correct: “In the article, the researchers argue that climate change is accelerating.”

3. Pronoun Case

Pronouns take different forms depending on their grammatical role in a sentence.

RolePronounsExample
Subject (nominative)I, he, she, we, they, who”She and I studied together.”
Objectme, him, her, us, them, whom”The award was given to him and me.”
Possessivemy/mine, his, her/hers, our/ours, their/theirs, whose”That is her research.”

Trick for compound subjects/objects: Remove the other person and test with the pronoun alone. “Her and I plan to travel.” → Remove “I”: “Her plans to travel.” (wrong) → “She and I plan to travel.” (correct)

4. Who vs. Whom (and Which vs. That)

Use the he/him substitution test for who/whom:

  • If you would use “he/she” → use who
  • If you would use “him/her” → use whom

“Who/whom did she call?” → “She called him.” → use whom “Who/whom won the prize?” → “He won the prize.” → use who

who/whomPeopleEither”The scientist who discovered it…“
whichThings/animalsNonrestrictive (with commas)“The experiment, which lasted a year, was successful.”
thatPeople/thingsRestrictive (no commas)“The experiment that lasted longest was the most successful.”

5. Pronoun Consistency

Once a pronoun is established to refer to people in general, it must remain consistent throughout the passage. Do not switch between “one,” “you,” and “they” when all refer to the same general group.

Wrong: “When one studies consistently, you tend to perform well.” Correct: “When one studies consistently, one tends to perform well.”

Wrong: “A student should organize their time, and then you can focus on difficult topics.” Correct: “A student should organize their time, and then they can focus on difficult topics.”

Pitfalls and Common Mistakes

Pitfall 1: Nouns Between Antecedent and Pronoun

Description: The SAT places intervening nouns between the antecedent and pronoun to mislead students into agreeing the pronoun with the wrong noun.

Wrong: “The members of the jury could not make up its minds.” Correct: “The members of the jury could not make up their minds.” Fix: Identify the true antecedent by asking “What does the pronoun logically refer to?” The subject of the sentence (“members”) — not the object of a preposition (“jury”) — is usually the antecedent.

Pitfall 2: Indefinite Pronoun Trap

Description: Indefinite pronouns like “everyone,” “someone,” “each,” “either,” and “neither” are grammatically singular, but students naturally use “their” because it sounds inclusive.

Wrong: “Everyone should bring their own materials.” Correct: “Everyone should bring his or her own materials.” (SAT formal standard) Fix: Memorize that these indefinite pronouns are singular: everyone, everybody, someone, somebody, anyone, anybody, no one, nobody, each, either, neither.

Pitfall 3: Ambiguous Pronoun Reference

Description: A pronoun in the answer choices refers equally well to two or more nouns in the passage, creating vague reference.

Wrong: “After the director met with the producer, she decided to rewrite the script.” (Who decided?) Correct: “After the director met with the producer, the director decided to rewrite the script.” Fix: When a pronoun could logically refer to more than one noun, replace it with the specific noun. On the SAT, answer choices that replace a vague pronoun with a specific noun are usually correct.

Pitfall 4: Wrong Pronoun Case in Compound Constructions

Description: Students use object pronouns where subject pronouns are required (or vice versa) in compound constructions.

Wrong: “Her and the team presented the findings.” Correct: “She and the team presented the findings.” Fix: Remove the other person in the compound. “Her presented the findings” sounds wrong → use “she.”

Pitfall 5: Using “Which” Where “That” Is Required

Description: “Which” introduces nonrestrictive (nonessential) clauses set off by commas. “That” introduces restrictive (essential) clauses with no commas. Students sometimes use “which” in restrictive clauses.

Wrong: “The study which showed the clearest results was published first.” Correct: “The study that showed the clearest results was published first.” (identifying which study — essential → “that,” no commas) Fix: If you can remove the clause and the sentence still makes clear sense, use “which” (with commas). If removing the clause changes the meaning, use “that” (no commas).
