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.

Chalk boards also were commonly used in keeping credit, score, etc., hence figurative use of chalk it up (1903).
