"I" is used as the subject of a verb. This means it's the one performing the action.
* Examples:
* *I* went to the store.
* *I* am happy.
* *I* like pizza.
"Me" is used as the object of a verb or preposition. This means it's receiving the action or being acted upon.
* Examples:
* John gave the book to *me*. (Object of the preposition "to")
* She saw *me* at the park. (Object of the verb "saw")
Tricky Situations:
* Compound Subjects and Objects: When "I" or "me" are part of a compound subject or object, use the same rules:
* Subject: My friend and *I* went to the movies.
* Object: The teacher gave homework to my friend and *me*.
* After "Than" or "As": These are tricky!
* *Incorrect:* She is taller than *I*.
* *Correct:* She is taller than *me*. (Imagine the complete sentence: "She is taller than I am.")
* Between "And" and "Or": Always use the pronoun you'd use if it were alone:
* *Correct:* My brother and *I* are going.
Key Points:
* Think about the action: Who is doing the action? Who is receiving the action?
* Isolate the pronoun: If you're unsure, try removing other parts of the sentence to make it simpler.
