The word "witticism" is a relatively modern English coinage, emerging in the late 17th century. It was humorously modeled after the word "criticism," applying the same "-icism" suffix to the root "witt-," which derives from Old English witt, meaning "mind, intellect, or sense." This root is part of a widespread Germanic family, ultimately traceable to the Proto-Indo-European root weid-, meaning "to see" or "to know," which also gives us words like "wise" and "vision." Thus, a witticism is literally the "practice or action of wit," a clever verbal expression born from sharp intellect and perception.
