[Middle English, perhaps alteration (influenced by mous, mouse) of Anglo-Norman *dormeus, inclined to sleep, hibernating, from Old French dormir, to sleep; see dormant.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

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 .
