flair

In the 14th century, if someone told you that you had flair (or flayre as it was then commonly spelled), you might very well take offense. This is because in Middle English flayre meant "an odor." The word is derived from the Old French verb flairier ("to give off an odor"), which came, in turn, from Late Latin flagrare, itself an alteration of fragrare. (The English words fragrant and fragrance also derive from fragrare.) The "odor" sense of flair fell out of use, but in the 19th century, English speakers once again borrowed flair from the French—this time (influenced by the Modern French use of the word for the sense of smell) to indicate a discriminating sense or instinctive discernment.
