13c., from O.Fr. bovier "herdsman," from L. bovis, gen. of bos "cow, ox." Later re-borrowed (1581) from Du. boer, from M.Du. gheboer "fellow dweller," from P.Gmc. base *bu- "dwell" (cf. second element of neighbor). Original meaning was "peasant farmer" (cf. Ger. Bauer, Du. boer, Dan. bonde), and in Eng. it was at first applied to agricultural laborers in or from other lands, as opposed to the native yeoman; negative connotation first attested 1562 (in boorish), from notion of clownish rustics. Boorishness is attested from 1794.
