Question: "What do identifiers mean in algorithmic languages"?
I think the semantics of the entities in question. For example, a set identifier represents the semantics of a collection of elements. It is essential that not the name of this set, namely the semantics.

Answer 1

An identifier is the name of an entity - a variable, a function, a label, a template, a macro, and so on.
And you write about some types / classes, so they reflect just the semantics.
