sandpaper
UK: ˈsændˌpeɪpə | US: ˈsændˌpeɪpər
n. a strong paper coated with sand or another abrasive, used for smoothing or polishing surfaces.
vt. to smooth or polish with sandpaper.
The word "sandpaper" is a straightforward compound of "sand" (Old English sand, meaning granular abrasive material) and "paper" (from Latin papyrus, via Old French papier). It emerged in the early 19th century to describe abrasive-coated paper, reflecting its literal function. The logic is transparent: "sand" denotes the gritty texture, while "paper" refers to the backing material.
