ACT English: Use Subject and Object Pronouns in the Correct Case

Subject case pronouns (I, he, she, we, they) are used when the pronoun performs an action. Object case pronouns (me, him, her, us, them) are used when the pronoun receives an action or follows a preposition. Example: "I sent her a message." "I" is subject (sends), "her" is object (receives message). Example: "Between you and me, I think that plan won't work." "Me" follows the preposition "between," so it's object case. Wrong: "Between you and I" (incorrect; should be "me"). This single rule resolves nearly all pronoun case errors on ACT English; master it and you'll never miss a pronoun case question.

Test yourself: "Him and me went to the store" or "He and I went to the store"? Both pronouns perform an action (went), so both are subject case: "He and I." Another test: "The teacher gave my friend and I a high grade" or "The teacher gave my friend and me a high grade"? Both pronouns receive the action (gave), so both are object case: "gave me/us." Correct: "The teacher gave my friend and me a high grade."

Trap 1: Using "me" when "I" is correct, especially in compound subjects. "My brother and me want to go" sounds natural but is wrong; both pronouns are subjects, so: "My brother and I want to go." Test: Would you say "me want to go"? No, so "me" is wrong in the compound. Trap 2: Using "I" when "me" is correct, especially after prepositions. "This is between you and I" sounds formal, but "between" is a preposition, so it requires object case: "between you and me." When you're unsure, isolate the pronoun: "Would I say this alone?" If the answer is no (e.g., "me want" is wrong), your case is wrong in the compound too.

Before you lock in a pronoun case answer, ask: Is this pronoun the subject (doing an action) or the object (receiving an action or following a preposition)? Your answer determines the correct case.

Sentence 1: "Him and her went to the movies." Error: Both pronouns are subjects (performing the action "went"), so use subject case. Fix: "He and she went to the movies." Sentence 2: "The coach gave him and I instructions." Error: Both pronouns receive an action (coach gave to them), so use object case. Fix: "The coach gave him and me instructions." Sentence 3: "Between you and me, that idea won't work." This is actually correct; "me" follows the preposition "between," so object case is right. Sentence 4: "Us and them worked together on the project." Error: Both pronouns are subjects (worked), so use subject case. Fix: "We and they worked together on the project." Each error illustrates a common mistake in identifying whether a pronoun is subject or object.

Do this drill daily for one week and pronoun case errors will become obvious to you. By test day, you'll choose the correct case automatically without hesitation.

Pronoun case questions appear regularly on ACT English and are among the most straightforward to get right once you know the rule. Subject vs. object case is a binary choice with a clear rule; once you internalize it, you'll answer these questions with high accuracy and never miss a pronoun case point again.

This week, focus on learning and applying the subject/object case rule. Drill ten sentences daily. By test day, pronoun case will be so automatic that you'll choose correctly without thinking.
