In linguistics, the word 'tree' is a signifier that represents the concept of a tree.
Signifier → It is formed from "sign" (from Latin "signum", meaning mark or symbol) and "-ifier" (from Latin "-ificare", meaning to make or cause). The word "signifier" refers to something that makes a mark or represents something else, particularly in the context of language and semiotics.
Think of a 'mark' or 'symbol' ('sign') that 'makes' or 'causes' something to be understood ('-ifier'). This helps you remember that a signifier is something that represents or indicates meaning.
