The difference between I and me
Both I and me are 1st person singular pronouns, which means that they are used by one person to refer to himself or herself. I is the subject pronoun, used for the one "doing" the verb, as in these examples:
I am studying for a Russian test. (I is the subject of am studying.)
I can speak Russian, but I can't read it very well. (I is the subject of can speak and can’t read.)
Me is the object pronoun, used as the object (or receiver) of the action of the verb, as in these examples:
My math teacher encouraged me to come for extra help after school. (Me is the object of encouraged.)
She asked me to bring my homework. (Me is the object of asked.)
Please let me know if you need any clarification. I'm always happy to answer your questions.
