SAT Pronoun-Antecedent Agreement: Matching Pronouns to Their Nouns

A pronoun is a word that stands in for a noun. The noun it refers to is called the antecedent. In the sentence "Sarah lost her keys," the antecedent is "Sarah" and the pronoun is "her." Pronouns must agree with their antecedents in two ways: number (singular or plural) and person (first, second, or third). "Sarah lost her keys" is correct because "Sarah" is third-person singular, and "her" is third-person singular. If you write "Sarah lost their keys," there is a mismatch because "Sarah" is singular but "their" is plural. Some common pronouns are he/him/his (singular), she/her/her (singular), it/it/its (singular), they/them/their (plural), and we/us/our (plural). To identify pronoun errors, find the antecedent (the noun the pronoun refers to) and check that the pronoun's number and person match the antecedent's number and person. This mechanical process catches most pronoun errors without requiring you to memorize complex rules.

Pronouns can be ambiguous if there are multiple possible antecedents. In "The teacher asked the student if he understood the assignment," does "he" refer to the teacher or the student? Context usually clarifies, but ambiguous pronouns are an error if the reader cannot confidently determine what the pronoun refers to. Similarly, if a pronoun has no clear antecedent, it is an error. "It was sunny in the morning, and it rained in the afternoon" uses "it" in impersonal constructions (weather), which is standard and correct. But "Sarah met with Emma about her concerns" is ambiguous: does "her" refer to Sarah or Emma? Rewriting to "Sarah met with Emma about Emma's concerns" or "Sarah met with Emma about her own concerns" clarifies the meaning.

A singular indefinite pronoun like "everyone," "somebody," or "each" requires a singular pronoun. "Everyone should bring their textbook" is technically incorrect in formal English, though it is increasingly accepted in casual usage. Formally correct is "Everyone should bring his or her textbook" or "Everyone should bring their textbook" (using singular they). The SAT typically treats "everyone" as singular and expects singular pronouns, so "Everyone should bring his or her textbook" is the safest choice. If a question offers singular and plural pronouns as options and the antecedent is "everyone," choose the singular option. Collective nouns that are singular (like "team" or "committee") should be paired with singular pronouns: "The team is proud of its accomplishments," not "their." If the collective noun is acting as plural individuals, use plural pronouns: "The committee members are proud of their individual contributions." These errors are tested because students often automatically use plural pronouns with collective nouns without thinking about whether the noun is singular or plural.

Compound antecedents joined by "and" are plural and require plural pronouns. "Sarah and Emma are proud of their grades" uses plural "their" because the compound antecedent "Sarah and Emma" is plural. If the antecedent is joined by "or" or "nor," the pronoun agrees with the nearest antecedent. "Either Sarah or the students will present their findings" is ambiguous because "either...or" suggests one or the other, not both. Clearer would be "Either Sarah or the students will present her/their findings" where the pronoun matches the closer antecedent. The SAT tests these scenarios, so identify the structure and apply the agreement rule correctly.

In formal writing, pronouns must agree in gender with their antecedents. If the antecedent is female, use she/her. If male, use he/him. If the antecedent's gender is unknown or mixed, traditional formal English uses he/him/his, though modern practice accepts they/them/their for unknown or non-binary individuals. The SAT generally follows traditional formal conventions, so if you see a sentence referring to "a student" and need to choose a pronoun for that student's action, choose a gender-neutral singular they or use he or she. Avoid using "it" for a person; "it" is for things or animals, not humans. Using "it" for a person is disrespectful and grammatically incorrect. Some sentences use job titles that are now understood to apply to any gender. "A doctor should listen to his patient" is outdated; better is "A doctor should listen to their patient" or "Doctors should listen to their patients." The SAT may test whether you recognize outdated gender language and can update it appropriately. The correct choice usually offers a gender-neutral option like "their" instead of gendered pronouns.

The pronoun "one" is formal and British. "One should do one's duty" is more formal and less common in American English than "People should do their duty." If the SAT includes the pronoun "one," it is testing whether you understand that "one" is a stylistic choice for formality, not a grammatical error. Use "one" consistently if you start with it: "One must do one's best," not "One must do their best" (mixing "one" and "their" is inconsistent). Most SAT sentences use pronouns other than "one," so this is a minor consideration, but be aware of it if "one" appears in the sentence.

Pronoun case refers to the form a pronoun takes based on its function in the sentence. Subject pronouns (I, he, she, we, they) perform the action. Object pronouns (me, him, her, us, them) receive the action or follow a preposition. Possessive pronouns (my, his, her, our, their) show ownership. A common error is using an object pronoun where a subject pronoun is needed. "Me and Sarah went to the store" should be "Sarah and I went to the store." Another common error is confusing "its" (possessive) and "it's" (contraction of "it is"). "The dog lost its collar" (possessive, no apostrophe). "It's raining" (contraction of "it is," with apostrophe). The SAT tests these distinctions regularly, so practice identifying case errors and correcting them. When you see a pronoun, ask yourself whether it is performing an action (subject case), receiving an action (object case), or showing possession (possessive case), and choose the pronoun form that matches.

The pronoun "who" is subject case, and "whom" is object case. "Who is calling?" (subject). "To whom are you speaking?" (object, after the preposition "to"). Many native speakers struggle with "who" vs. "whom," and the distinction is becoming less strictly enforced in modern English. However, the SAT may test it, so if you see both options, choose "who" for subject actions and "whom" for object actions or after prepositions. A helpful tip is to replace "who/whom" with "he/him": "He is calling?" uses subject case, so "who." "To him are you speaking?" uses object case, so "whom." This substitution method works reliably and avoids needing to remember the case names.
