A performer who is skilled at escaping from restraints or traps, often as part of a magic act or show.
The escapologist amazed the audience by escaping from a locked box underwater.
Escapologist is formed from "escape" (from Latin "excapere", meaning to get away) and "-ologist" (from Greek "-logia", meaning one who studies or specializes in). The word refers to a person who specializes in the art of escaping from restraints or confinement.
Think of someone who 'gets away' ('escape') and is an expert ('-ologist') in doing so — that's what an escapologist does.
