mask
UK: mɑːsk | US: mæsk
n. a covering for the face, worn for disguise, protection, or performance.
vt. to conceal or disguise something.
The word "mask" traces back to the Italian maschera, which likely derived from Latin masca (meaning "specter" or "nightmare"). Its deeper origins are uncertain but may link to Arabic maskhara ("mockery") or Pre-Latin roots. Over time, the term evolved from supernatural connotations to its modern sense of a face covering for disguise, protection, or theatrical use. The logic reflects a shift from fear (specters) to practicality (concealment).
