Could someone please tell me what the difference between "someone" and "someone else" is?
I heard these sentences many times:
She is talking to someone.
She is talking to someone else.
Likewise:
I want to go somewhere
I want to go somewhere else

We use else after indefinite pronouns to refer to people or things in addition to the ones we already mentioned.
All the family came, but no one else. If Michael can’t come we’ll ask somebody else. So that's eggs, peas and chips. Do you want anything else?
