Both "me and my friend" and "my friend and I" can be correct, but their usage depends on the context of the sentence.
- "Me and my friend": This form is used when the pronoun is the object of the sentence or the object of a preposition.
Example: "He invited me and my friend to the party." (Here, "me and my friend" is the object of the verb "invited.")
- "My friend and I": This form is used when the pronoun is the subject of the sentence or the subject of a verb.
Example: "My friend and I went to the movies." (Here, "my friend and I" is the subject of the verb "went.")
To determine whether to use "me and my friend" or "my friend and I," you can remove the other person from the sentence and see if it still makes sense. For example:
"He invited me to the party." (Correct)
"Him invited I to the party." (Incorrect)
"I went to the movies." (Correct)
"Me went to the movies." (Incorrect)
So, in summary, both forms are correct, but it's essential to use them in the appropriate grammatical context. If the pronoun is the subject of the sentence or the subject of a verb, use "my friend and I." If the pronoun is the object of the sentence or the object of a preposition, use "me and my friend."
