Origin

Old English cealc (also denoting lime), related to Dutch kalk and German Kalk, from Latin calx (see calx).

Old English cealc, the forerunner of chalk, also meant ‘lime’. It came from Latin calx ‘lime’, which is also the source of calcium [19th]. When we say by a long chalk, meaning ‘to a great degree, by far’ (and not by a long chalk, ‘not at all’), the ‘ long chalk’ refers to the length of a line of chalk marks or tallies drawn on a blackboard. This may originally have been in the context of a pub game, where points scored were marked up on the blackboard, or perhaps in the classroom, with a teacher chalking up pupils' marks for schoolwork. In either case, a long line of chalk marks against your name would mean you were a long way ahead of the others.
