Sense: adjective/3

All four words describe someone with pleasing social qualities, but they differ in emphasis. Refined focuses on natural grace and self-control in social behaviour — a refined person knows how to act without being told. Polished suggests smoothness acquired through practice and repeated exposure; a polished speaker has delivered many speeches. Cultivated implies conscious development of taste through study — a cultivated art lover has read widely and visited many galleries. Elegant is the most visual of the four, describing graceful appearance, movement, or style rather than behaviour. For example: 'Her refined manners kept the conversation pleasant even when opinions differed. Her polished presentation showed hours of rehearsal. Her cultivated appreciation for opera came from years of attending performances. And her elegant gown drew admiring looks across the room.'

Etymology

LatinFrenchEnglish

Refined traces back to the Latin verb finire meaning 'to finish' or 'to bring to an end'. Combined with the prefix re- ('again'), the literal idea was 'to finish again' — that is, to go through a process a second time to make it better. In the 1500s, English adopted refine for the purifying of metals and sugar by removing impurities. By the 1600s, the word had developed a social sense: just as impurities are removed from metal, 'coarse' behaviour could be removed from a person, leaving them polite and cultured.
