語源

Inherited from 中期英語 buttok, probably from 古期英語 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 古期英語 precursor of butt +‎ -ock (diminutive suffix).

• The plural form is usually used in the singular sense for a single person's posterior, often informally called butt (North America) or bum (Britain). It is rarer to refer to only a single buttock, which is then usually specified as left or right.
