Etymology

The word "quirky" derives from "quirk," which originally meant a clever twist or evasion (16th century, of uncertain origin, possibly from Germanic or Old Norse). By the 18th century, "quirk" evolved to mean an idiosyncratic habit or peculiarity. The suffix "-y" (from Old English "-ig") transforms nouns into adjectives, giving "quirky" its modern sense of "full of quirks" or "unconventionally charming."
