chalkboard
UK: ˈtʃɔːkbɔːd | US: ˈtʃɔːkbɔːrd
n. a smooth, rigid panel, typically dark-colored, used for writing or drawing with chalk.
The word "chalkboard" is a compound of "chalk" (from Old English "cealc," referring to the writing material) and "board" (from Old English "bord," meaning a flat plank or surface). It emerged in the 19th century as a descriptive term for a surface designed specifically for chalk-based writing, replacing earlier terms like "blackboard." The logic is straightforward: a "board" meant for "chalk."
