¿"A mí me gusta" o "a mi me gusta"?
Which one is grammatically correct?
1 Answer
A mí me gusta is correct
The a counts as a preposition and you use prepositional forms after, see this lesson:
Basically, mí carries and accent to distinguish it from the possessive, ti does not because the possessive is tu (distinguished from the subject pronoun, tú by the accent on the latter)- the rest of the objects of pronouns are the same as the subject pronouns.
