Did you know?

The word clue was originally a variant spelling of clew, meaning “ball of thread or yarn.” Our modern sense of clue, “guide to the solution of a mystery,” grows out of a motif in myth and folklore, the ball of thread that helps in finding one’s way out of a maze. Of these stories the best known is the myth of Theseus and the Minotaur. In the myth, Theseus unravels a ball of thread as he searches for the monstrous Minotaur in the Labyrinth. After killing the Minotaur, he retraces his steps out of the maze by rewinding the thread.
