Prepositional Pronouns (Mí, Ti, Sí, Él, Ella, Usted, Nosotros, Ellos, Ustedes)

When a Spanish pronoun comes after a preposition — words like a, de, para, por, con, en, sin, sobre — it takes a special form called a prepositional pronoun. For the most part these forms look like the subject pronouns you already know, but two of them are unique: mí and ti.

The full table

Notice that only the first-person singular (mí), the second-person singular (ti), and the reflexive form (sí) are different from the subject pronouns. Every other person stays the same.

Everyday examples

Mí has an accent, ti does not

One of the most common writing mistakes in beginner Spanish is leaving the accent off mí. You need it to distinguish mí (the prepositional pronoun, meaning "me") from mi (the possessive adjective, meaning "my"). Ti, on the other hand, has no accent — there is no other word it could be confused with.

Here you can see both forms in one sentence: mi (my) with no accent, and mí (me) with one.

The reflexive sí

The form sí is the prepositional pronoun that refers back to the subject of the verb, in any third person (singular or plural) — it corresponds to the reflexive se. It usually appears with the word mismo/a/os/as for emphasis.

This sí also has an accent, to distinguish it from the conjunction si (meaning "if") and the affirmative particle sí (meaning "yes" — same spelling, different function).

Two famous exceptions: entre, según, hasta, incluso, excepto, salvo, menos

A handful of prepositions and preposition-like words break the rule and are followed by the subject pronouns yo and tú instead of mí and ti. Don't fight this — just memorize them.

After con, something unusual happens

The preposition con combines with mí, ti, and sí into single words: conmigo, contigo, consigo. These are important enough to have their own dedicated page. For all other persons, con just sits in front of the normal prepositional pronoun: con él, con nosotros, con ustedes.

Not to be confused with object pronouns

It's easy to mix up prepositional pronouns with direct and indirect object pronouns. The difference is simple: if the pronoun follows a preposition, use this page's forms. If it's the direct or indirect object of a verb, use me, te, lo, la, le, etc.

In the first sentence, me is an object pronoun directly attached to the verb. In the second, mí comes after the preposition para.
