We were disturbed by the mayoral candidate's flippant response to a question about the city's debt.
"Sonja Richter, who plays Mona, works wonders with just a fearful glance or flippant smirk, and it's obvious she's mastered this role." -- From a movie review in Digital Journal, September 10, 2010
Did You Know?
"Flippant" did something of a flip-flop shortly after it appeared in English in the late 16th century. The word was probably created from the verb "flip," which in turn may have originated as an imitation of the sound of something flipping. The earliest senses of the adjective were "nimble" and "limber." One could be flippant not only on one's feet, but also in speech-that is, someone "flippant" might have a capacity for easy, flowing speech. Such flippancy was considered a good thing at first. But people who speak freely and easily can sometimes seem too talkative, and even impertinent. By the end of the 18th century, the positive sense of "flippant" had slipped from use, and the "disrespectful" sense had taken its place.
