Pronouns as Objects of Prepositions

Subject Pronouns	Obj. Prep. Pronouns
yo	mí
tú	ti
él	él
ella	ella
usted	usted
nosotros/as	nosotros/as
vosotros/as	vosotros/as
ellos/as	ellos/as
ustedes	ustedes

Use this second set of pronouns to replace the noun that comes immediately after a preposition.

Whenever mí follows the preposition con, the two words combine to form conmigo.

¿Por qué no vienes conmigo?
Why don't you come with me?

Whenever ti follows the preposition con, the two words combine to form contigo.

No voy contigo, voy con ellos.
I'm not going with you, I'm going with them.

Whenever you want to say "with him, with her, with you (formal), with them, with you-all (formal)" there are two possibilities. If the pronoun is referring to the subject of the sentence, use consigo. If the pronoun does not refer to the subject of the sentence, usecon + the appropriate pronoun.

Pronoun does refer to the subject

He took the pens with him(self).
Él llevó las plumas consigo.

Why don't you take a book with you(rself)?
¿Por qué no lleva un libro consigo?

Pronoun does not refer to the subject

They live with him.
Ellos viven con él.

I don't want to talk to you.
No quiero hablar con usted.
