Is “either” only used with two options?
I'm trying to find a way to express that there are three alternatives in a sentence. For example, if there were two alternatives, I could say:
That person could be either Alice or Lily.
But what if I want to add a third person? Can I say:
That person could be either Alice, Lily or Lucy.
I looked up in the dictionary and it says:
either/or: an unavoidable choice between two alternatives.
Well, how do I express an unavoidable choice between three or more alternatives?
