Questions & Answers about Tu tiempo es importante para mí.
Why does mí have an accent mark at the end of the sentence?
The accent mark is used to tell the difference between the prepositional pronoun mí (me) and the possessive adjective mi (my). Because it comes right after the preposition para, we use the pronoun mí.
Why does this use para instead of a if the English translation says "to me"?
Why doesn't Tu have an accent mark here?
Without the accent mark, tu is the possessive adjective meaning "your" (as in "your time"). With the accent mark, tú is the subject pronoun meaning "you".
