From Middle English dormous, of uncertain origin. Possibly from dor-, from Old Norse dár (“benumbed”) + mous (“mouse”). More at doze, mouse.
Although the word has come to be associated as an Anglo-Norman derivative of Old French dormir (“to sleep”), no such Anglo-Norman word is known to have existed .
