Etymology
Inherited from Middle English buttok, probably from Old English buttuc (“end; end piece”; also, “short piece of land”). Attested with its current anatomical meaning since 1300. A diminutive form of what is presumably the Old English precursor of butt + -ock (diminutive suffix).
Webster’s 1913
- noun The part at the back of the hip, which, in man, forms one of the rounded protuberances on which he sits; the rump.
