the adverb "vulgarly" is built upon its adjective form "vulgar," which traces directly to latin vulgaris. this latin term originated from vulgus, meaning "the common people, the multitude." in ancient rome, vulgaris described anything pertaining to the general populace, carrying a neutral sense of "ordinary" or "public." over centuries, particularly through the lens of social hierarchy and classical education, the word's connotation in english shifted from merely "common" to "lacking refinement," "coarse," or "indecent," reflecting a perceived contrast between popular and elite culture. the suffix "-ly," of germanic origin, is a standard and productive adverb-forming element in english, attaching to adjectives to denote manner. thus, "vulgarly" literally means "in a common manner," which semantically evolved to encompass both the neutral sense of "commonly" and the pejorative sense of "in a coarse or tasteless way."
