Attention, “Bridgerton” fans. The adjective “genteel” came into English in the 16th century from the French word “gentil” (“well-born”), meaning “fashionable, stylish.” From the 17th century to the 19th century, it expanded in usage to mean “of a good social position” and “having the manners of a well-born person.” In the 19th century, however, “genteel” acquired an ironic implication; accusing someone of genteel manners now implies their level of refinement is over the top. It might land them in the gossip hounds’ sights.
