Learn Spanish (Latin America): ¿Esa sorpresa es para mí?

In Spanish, when you want to say "me" after a preposition like para (for), a (to), or de (from), you must use a specific set of pronouns. Instead of the subject pronoun yo (I), you use the prepositional pronoun mí.

Why does mí have an accent mark here?

The accent mark is just there to tell it apart from another word that sounds exactly the same: mi (without an accent). The word mi means "my" (as in mi sorpresa), whereas mí with the accent means "me" after a preposition.

Why is it esa sorpresa and not ese sorpresa?

Words like "this" and "that" change to match the gender of the noun they describe. Because sorpresa is a feminine noun, you must use the feminine form esa (that) instead of the masculine form ese.

Why does this sentence use es rather than está?

When you are talking about who a gift is for, who something belongs to, or what its purpose is, you always use the verb ser. We use es here because we are stating who the surprise is intended for, which is treated as a permanent fact about it.
