Origin
From Middle English asse, from Old English assa, back-formed from assen (“she-ass”), from Celtic (compare Old Irish asan, Old Cornish asen), from Latin asinus. Displaced Old English esol, from Proto-West Germanic *asil, also a loanword from the same Latin word. Sense “stupid person” from the animal's reputation for stubbornness, going back to antiquity (compare Latin asinus (“slow-witted person”)).
