snoozer

An informal, somewhat whimsical adjective meaning asleep. Typically used in a lighthearted or literary register to describe someone who is sleeping, particularly when the speaker wants to avoid bluntness or add a touch of gentle humor. More likely to appear in writing or affected speech than in everyday conversation. The "a-" prefix construction echoes older English forms like "afoot" or "afire," giving the word a slightly archaic flavor.

(slang) asleep.

(British, rare) To nuzzle affectionately.
