Did you know?

Given the spelling and definition of wiseacre, you might guess that the word was formed directly from the familiar adjective wise. And you might be wise to think so—a wiseacre, after all, is someone who thinks or pretends they're wiser (more crafty or knowing) than they are. But you would, alas, also be wrong. Unlike wisecrack and wisenheimer, wiseacre came to English not from wise but from the Middle Dutch word wijssegger, meaning "soothsayer." Wiseacre first appeared in English way back in the 16th century, while all those other wise words appeared centuries later. The etymologies of wiseacre and wise are not completely distinct, however; the ancestors of wiseacre are loosely tied to the same Old English root that gave us wise.
