I think axiom should fit, but according to its official definition, an axiom is a statement that is taken to be true, and as far as I know, a word can’t make an statement by its own.

Maybe onomatopoeia. The word for the “crack” sound is “crack”. The definition of “crack” is “crack”.
The definition of crack in that instance would be something along the lines of: “The snapping sound the air makes when creating a small sonic boom. Like that of a whip cutting through the air.”
Even onomatopoeia has synonyms. Like some people say Atchoo. Some say kerchew. And then other languages say other words for the same sound.
