Word Origin & History
vulgar1391, "common, ordinary," from L. vulgaris "of or pertaining to the common people, common, vulgar," from vulgus "the common people, multitude, crowd, throng," from PIE base *wel- "to crowd, throng" (cf. Skt. vargah "division, group," Gk. eilein "to press, throng," M.Bret. gwal'ch "abundance," Welsh gwala
"sufficiency, enough"). Meaning "coarse, low, ill-bred" is first recorded 1643, probably from earlier use (with reference to people) with meaning "belonging to the ordinary class" (1530). Vulgarian "rich person of vulgar manners" is recorded from 1804.
