Answer 1

It's from the verb: decir---try looking up the conjugation for this word and then post something back. We'll guide you from there.

Answer 2

Welcome to the forum. As Jason said, Diga is the imperative form of the verb Decir (to say). But it is used in many places when someone answers the telephone, like we say, "Hello", sort of a polite way of saying, "Talk to me".
