How did the the word clue come to mean a hint?

Answer 1

clue originally meant for something to be rolled, like a ball of yarn. In Greek Mythology, Jason was given a ball of yarn from Medea to help him escape the minotaurs labyrinth. She was given a hint about this from Daedalus. So it probably became a common phase "to give someone a clue" instead of give to them a hint (kinda like the phrase "all the way to timbucktoo" means a long way to go when timbucktoo is actually a shipping town in Africa) and eventually the word clue was added to the dictionary as a helpful hint

Answer 2

The Lord Clue of Whittington used to drop hints about him wanting to have sex with his wife all the time, until one day his penis erupted due to lack of ejaculation. he used to call his penis Clue named after himself so people decided to say to him "you dont have a Clue do you?" All truth Bruv
