Term: Pronouns

Copying from a Dictionary:

Any of a small set of words (such as I, she, he, you, it, we, or they) in a language that are used as substitutes for nouns or noun phrases and whose referents are named or understood in the context.

Colloquially, everyone has pronouns. It's like a name, you can ask for them if you don't know, and respect them when you do.
