Does throwing on a jaunty hat make someone appear more genteel? Maybe, but something more definitive links the words: both jaunty and genteel come from the French word gentil, meaning "of aristocratic birth." Genteel was borrowed first to describe things associated with aristocratic people. Jaunty joined the language just a few years later in the mid-17th century as a synonym of stylish and also as a synonym for genteel. While genteel has maintained its associations of propriety and high social class, jaunty has traipsed into less stuffy territory as a descriptor of tunes and hats and other things that suggest lively confidence.
