Late Middle English: variant of clew. The original sense was 'a ball of thread'; hence one used to guide a person out of a labyrinth. sense 1 of the noun dates from the early 17th century.

  • Our word clue is a modern spelling of the old word clew, ‘a ball of thread’. The idea here is of string or thread being used to guide a person out of a maze by tracing a path through it. The most famous example is that of the Greek hero Theseus, who killed the monstrous bull-headed Minotaur in its lair and then escaped from the Labyrinth, an underground maze of tunnels. This he was able to do because the princess Ariadne gave him a ball of twine, which he unravelled as he went in and followed back to find his way out again. From this a clue became anything that you can follow to get a solution.
