Well, you understand the basic idea of a scope for an identifier, right? Its something like a syntactic or operational region within which the identifier has a fixed meaning. If you use that same identifier outside its scope, it means something different. So "the manager" in one office refers to Fred, but in a different office refers to Bill: offices are scopes for that particular identifier. In a functional programming language, variable binders define scopes for the variables they bind.
