In Greek mythology, Theseus used a ball of thread (given to him by Ariadne) to navigate the Minotaur's labyrinth — he tied one end at the entrance and followed it back to escape. The Old English word for a ball of yarn was 'clew' or 'clue'. Over centuries, the meaning shifted from 'a physical thread that guides you out' to 'any piece of evidence that leads you to a solution'. Every detective who follows a 'clue' is unknowingly referencing an ancient labyrinth.
The word 'clue' is embedded so deeply in detective fiction, mystery games, and everyday problem-solving that discovering it carries an origin story — a literal thread through a literal maze — makes the metaphor suddenly feel alive.
