Etymology
The journey of 'mask' is one of concealment and performance, traveling across cultures into English. It likely entered through French and Italian theatrical traditions, where a 'maschera' denoted a character or disguise worn by an actor. The deeper roots are obscure but may connect to Arabic terms for jesters or to words meaning 'black', hinting at early disguises made from darkening the face. Over time, the meaning broadened from a physical face covering to any figurative means of hiding one's true nature or intentions.
Analysis
The word is a simplex loanword. Its core form entered English from Middle French 'masque', which came from Italian 'maschera' or Medieval Latin 'masca'. The ultimate origin is uncertain but may be from Arabic 'maskharah' (buffoonery, mockery) or a pre-Latin source meaning 'black' (linking to soot used for disguise).
