Origin of chipmunkof Algonquian origin, originally
Origin of chipmunkAlteration of obsolete chitmunk, perhaps from Ojibwa ajidamoon&qnodot;, red squirrel.
(third-person singular simple present chipmunks, present participle chipmunking, simple past and past participle chipmunked)
1832; alteration (influenced by chipping squirrel) of earlier chitmunk, from older Ojibwe ačitamo˙nˀ (“squirrels”) (modern ajidamóóg), literally ‘those who descend headlong’, from ačit- (“headfirst, face-down”) (compare modern ajijibizo (“he falls headfirst”), ajidagoojin (“he hangs upside down”)). The verb developed due to the high-pitched voices of the chipmunks in the film Alvin and the Chipmunks.
