Word History

Etymology

Noun

Middle English chalk, schalke "chalk, lime," going back to Old English cealc, calc "limestone, chalk, lime," going back to West Germanic *kalka- (whence also Old Saxon & Middle Dutch calc "lime," Old High German kalc, chalch "lime, chalk"), borrowed from Latin calc-, calx "lime, limestone," perhaps borrowed from Greek chalik-, chálix "gravel, rubble (used as building material)," of uncertain origin

Note: The attribution of the Latin word to Greek is conventional, though the meanings are divergent, and the syncope in the Latin word is irregular. Perhaps both words were borrowed independently from a third language. Compare calculus.
