Question

I am going ot buy my cousin a cd
voy a comprar mi primero un cd

is my translation correct

Answer 1

That looks good.

Answer 2

With an indirect object (my cousin) in Spanish it is always best to include the indirect-object pronoun. Because you are using "ir + a + infinitive" you have a choice between 2 positions:

a) Le voy a comprar a mi primo un disco compacto.

b) Voy a comprarle a mi primo un disco compacto.

NOTE: Try not to confuse "primero" = first with "primo" = cousin and don't forget the "a" we discussed in an earlier post!
