Apparently this oft used phrase has little to do with any cerebral stimulation to gain insight. The word ‘clue’ is actually derived from the name for the corner of a sail ‘clew’. There was a brass ring in the clew to which a clew line was fastened to hold the sail in place. If the clew became damaged then the ship had to remain where it was until the damage was repaired. Hence – get clued up.
