Which one of the sentences below do you think is grammatically correct?
1. Geeta and I went for a walk.
2. Geeta and me went for a walk.
If you guessed the first sentence, you’re right! However, don’t stress out if you guessed wrong. Many native English speakers get this rule confused.
I and me aren’t interchangeable and are used in different grammatical constructs:
I is a pronoun that serves as a subject of a sentence. In the first example, Geeta and I went for a walk, both I and Geeta are subjects of the sentence while went is the verb.
Me is a pronoun that serves as an object of a sentence. Me is needed when someone else is performing the action. To use the example above, it would be absolutely correct to say: Geeta took me for a walk. Geeta is the subject and me is the object in the sentence.
