Those whose quirk is to [zig](https://www.merriam-webster.com/dictionary/zig) while others zag (and conversely those who [zag](https://www.merriam-webster.com/dictionary/zag) while others zig) will appreciate the origins of today’s word. Not its etymological origins, mind you—no one knows whence quirk came—but the twists and turns of its meanings across the centuries. The oldest known use of quirk dates to the mid-1500s, and referred to a clever verbal [dodge](https://www.merriam-webster.com/dictionary/dodge) of the kind one might use to turn the tables on someone in an argument or debate. It didn’t take long for quirk’s meaning to expand to cover all kinds of twisty, turn-y things, from witty [retorts](https://www.merriam-webster.com/dictionary/retort) and curlicue flourishes made with ink on paper to the [vagaries](https://www.merriam-webster.com/dictionary/vagary) or twists of fate. The sense of quirk meaning “a peculiarity of action or behavior” refers to a twist of sorts as well, insofar as our quirks often flip others’ expectations of us, perhaps even causing them to [quirk](https://bit.ly/3S82Lkb) their eyebrows now and again. In a surprising twist, quirk began to be used as a verb meaning “to curve or twist” in the late 1800s.
