A mask is the face covering you put on, whether it's a surgical mask, a costume mask, or a figurative one hiding your true feelings. A masque is different: it's an old-fashioned word for an elaborate performance, once staged at royal courts, mixing dance, dialogue and song. Think of the -que spelling as a clue that it belongs to theatre history, not your bathroom cabinet.
The core difference
Mask is a covering (or the act of covering); masque is a type of stage entertainment.
- mask — a face covering, or to conceal something: He wore a mask to the costume party.
- masque — a courtly dramatic performance with dancing, dialogue and song: The queen commissioned a masque to celebrate the wedding.
How to tell them apart
Both words trace back to the same French and Italian roots, which is why they look so alike, but they split into separate jobs in English. Mask stayed close to its original sense of a physical face covering, then grew figurative uses: a smile can mask disappointment, and the word also covers concealing neurodivergent traits to appear more typical. Masque kept the theatrical meaning, describing the dance-and-song entertainments performed at royal courts, along with the words and music written for one.
The mix-up mostly happens in writing about history or drama, where masque shows up describing a Renaissance court spectacle and gets typed as mask by mistake. A simple check: if you can hold it or wear it, it's a mask; if you'd buy a ticket to watch it, it's a masque.
