What this lesson covers
Every pronoun in English has a case, which is its grammatical role or job. The case tells you whether a pronoun is doing the action (like I), receiving the action (like me), or showing possession (like my or mine). Choosing the right case makes your writing and speaking sound correct and clear. In this lesson, you'll learn to identify the three cases and use simple strategies—like the drop test for compound subjects—to pick the right pronoun every time.
The Three Cases of Pronouns
English pronouns change form depending on their job in the sentence. Subjective case pronouns are the ones doing the action or being described. These are I, you, he, she, it, we, and they. They appear as the subject of a sentence or after a linking verb.
Objective case pronouns receive the action or follow a preposition. These are me, you, him, her, it, us, and them. They appear as a direct object, indirect object, or object of a preposition.
Possessive case pronouns show ownership. These are my, your, his, her, its, our, their, mine, yours, his, hers, and theirs. They never use an apostrophe.
The key is figuring out what job the pronoun does in the sentence. Ask yourself: Is it doing something? Is something being done to it? Does it own something? Your answer tells you which case to use.

Choosing the Right Case in Simple Sentences
In a simple sentence with a single subject or object, most people choose the right case naturally. You wouldn't say "Me go to the store"—you'd say "I go to the store." You wouldn't say "She gave the book to I"—you'd say "She gave the book to me."
Problems arise when pronouns are part of compound subjects or objects—when you have two or more people joined by and or or. For example, is it "My friend and I went to the movies" or "My friend and me went to the movies"? The right answer is I, but many people say me because it sounds conversational. The sentence has a compound subject (my friend and I), so both pronouns need subjective case.
When you're unsure, use the drop test: remove the other person from the sentence and read it alone. "Me went to the movies" sounds wrong, so you know to use I. "They gave the award to him and... (drop her name)... they gave the award to I" sounds wrong, so you use me. This simple trick works almost every time.

Prepositions Always Take Objective Case
A preposition is a word that shows position or relationship, like in, on, between, among, for, to, with, from, at, by, and during. The pronoun that comes after a preposition is called the object of the preposition, and it always uses objective case.
This rule is especially important for two common mistakes. The first is "between you and I," which should be "between you and me." The pronoun me follows the preposition between, so it must be objective case. Similarly, "from John and I" is wrong—it should be "from John and me." Use the drop test here too: you wouldn't say "between I," so you don't say "between you and I."
The second mistake happens with who and whom. Who is subjective case and whom is objective case. After a preposition, use whom: "To whom should I give this?" not "To who should I give this?" Again, the preposition rule applies: the object of a preposition always takes objective case.

Possessive Pronouns Stand Alone
Possessive pronouns show that something belongs to someone. Unlike nouns, which add 's to show possession (the cat's toy), pronouns never use an apostrophe. The forms its, his, her, my, your, our, and their are always correct. Never write it's (which means "it is"), his', her's, my's, your's, our's, or their's—these are not real words.
Possessive pronouns can stand alone or come before a noun. "This backpack is mine" uses mine alone. "This is my backpack" uses my before the noun. Both are correct depending on what you're trying to say. The key is remembering that possessive case never needs an apostrophe, ever. If you see an apostrophe in a pronoun, it's either a contraction (like "it's" for "it is") or it's wrong.

Common Traps and How to Avoid Them
Beyond compound subjects and prepositions, a few other situations trip up writers. One is appositives—when you rename someone right after mentioning them. "We students are excited" is correct because we is subjective (it's the subject). "Us students are excited" is wrong. Drop test: "We are excited" works, but "Us are excited" doesn't.
Another trap is comparing people using than or as. "She is taller than me" sounds natural, but it can be wrong depending on what you mean. The full comparison is "She is taller than I am," so technically I is correct, not me. However, "than me" has become standard in everyday speech. For school writing, use the complete comparison and choose the case that matches.
Finally, watch out for reflexive pronouns (myself, yourself, himself, herself, itself, ourselves, yourselves, themselves). These are never the subject or object of a sentence. Don't write "John and myself went to the store." Write "John and I went to the store." Reflexive pronouns exist only to reflect back on another noun: "I taught myself Spanish" or "She gave herself a break."

Key terms
- Subjective case.
- The case a pronoun uses when it is the subject of a sentence or follows a linking verb. Examples: I, you, he, she, it, we, they.
- Objective case.
- The case a pronoun uses when it receives the action of a verb or follows a preposition. Examples: me, you, him, her, it, us, them.

Worked example
Choose the correct pronoun case in the following sentence: My sister and (me/I) made breakfast for our cousins and (they/them). Explain your choice using the drop test.
Let's break this sentence into two parts because there are two choices to make.
Part 1: My sister and (me/I)
This is a compound subject—the group doing the action (making breakfast). To use the drop test, remove "my sister" and read just the pronoun: "I made breakfast" sounds right, but "Me made breakfast" sounds wrong. Since the pronoun is the subject (doing the action), use subjective case: I.
Part 2: for our cousins and (they/them)
This is a compound object that follows the preposition for. Since all pronouns that follow prepositions use objective case, and this is a compound object, both pronouns need objective case. Use the drop test: "She made breakfast for them" sounds right, and "She made breakfast for they" sounds wrong. The correct choice is them.
Full sentence: My sister and I made breakfast for our cousins and them.
Remember: subjective case does the action, objective case receives it or follows a preposition, and the drop test works by letting you hear whether the pronoun alone sounds right.

Practice questions
Which sentence uses the correct pronoun case?
- Between him and I, this is our secret.
- Between him and me, this is our secret.
- Between he and me, this is our secret.
- Between him and they, this is our secret.
Answer: Between him and me, this is our secret.
The pronoun follows the preposition between, so it must be objective case. Me is correct, not I. The drop test helps: you would say "between me" alone, not "between I." The pronoun they is subjective case, so "between they" is wrong.
Rewrite the following sentence with the correct pronoun case: The coach asked Juan and I to stay after practice. Then explain why you made your change.
Answer: The coach asked Juan and me to stay after practice.
The compound Juan and me is the object of the verb asked (the coach asked whom?). Since the pronoun receives the action, it needs objective case. Me is correct, not I. The drop test: "The coach asked me" sounds right, but "The coach asked I" sounds wrong. This is a common mistake because and I sounds more formal than and me, but case depends on the pronoun's job, not on how formal it sounds.
Is the following sentence correct? If not, rewrite it: Us students are responsible for our own homework.
Answer: The sentence is incorrect. It should be: We students are responsible for our own homework.
The pronoun is an appositive (renaming "us students" or "we students"). The pronoun is the subject of the sentence—it's part of who is responsible—so it needs subjective case. We is correct, not us. The drop test: "We are responsible" works, but "Us are responsible" doesn't. Remember that possessive pronouns like our are separate from the case choice for the subject pronoun.
FAQ
- Is it okay to say "between you and I" if that's how I talk?
- No, not in school writing or formal speaking. Between you and me is the grammatically correct form because the pronoun follows the preposition between, and all prepositions take objective case. Even though "between you and I" is common in speech, it's considered incorrect. Make it a habit to use me after prepositions, and your writing will always be right.
- Why do we have to use the drop test? Can't I just listen to what sounds right?
- Not always. Many incorrect sentences sound natural to us because we hear them spoken that way often. For example, "Her and me went to the store" might sound okay in casual speech, but the drop test shows it's wrong: "Me went to the store" clearly doesn't work. The drop test removes the influence of everyday speech and lets you see the correct case logically. It's a tool that works when your ear might mislead you.
- Is there a difference between "its" and "it's"?
- Yes, a big one. Its is a possessive pronoun that shows something belongs to it: "The dog wagged its tail." It's is a contraction (a shortened form) that means "it is" or "it has": "It's raining" means "It is raining." The possessive pronoun its never has an apostrophe. A helpful trick: if you can replace the word with "it is" or "it has," use it's. Otherwise, use its.
- What's the rule with "who" and "whom"?
- Who is subjective case and whom is objective case, just like I and me. Use who when the pronoun is doing the action: "Who left this here?" Use whom when the pronoun receives the action or follows a preposition: "To whom should I give this?" and "Whom did you call?" The drop test works: substitute a pronoun in the same position. "He left this here" works, so use who. "Give this to him" works, so use whom. This is a tricky distinction, but the logic is the same as with other pronouns.
