Word Origin and History for chalk
n.

Old English cealc "chalk, lime, plaster; pebble," a West Germanic borrowing from Latin calx (2) "limestone, lime (crushed limestone), small stone," from Greek khalix "small pebble," which many trace to a PIE root for "split, break up." In most Germanic languages still with the "limestone" sense, but in English transferred to the opaque, white, soft limestone found abundantly in the south of the island. Modern spelling is from early 14c. The Latin word for "chalk" was creta, which also is of unknown origin.

v.

1570s, "to mix with chalk;" 1590s as "to mark with chalk," from chalk (n.). Related: Chalked; chalking. Old English had cealcian "to whiten." Certain chalk marks on shipped objects meant "admitted" or "shipped free," hence some figurative senses. Chalk boards also were commonly used in keeping credit, score, etc., hence figurative use of chalk it up (1903).
