- chalk (n.) Old English cealc "chalk, soft white limestone; 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."
- chalk (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).
