What do you say with them? con ustedes?
I know conmigo contigo, but I don't know the others. What is with them or with her?
2 Answers
Con ellos = with them
Con ustedes = with you all
Con ella - with her
Con él = with him
"Ellos" is 3rd person plural which is equivalent to "them", so it's "con ellos."
(Note: if "them" pertains to women, you say "con ellas".)
