Given the spelling and definition of "wiseacre," you might guess that the word derives from the sense of "wise" meaning "insolent" or "fresh"-the sense that gives us "wisecrack" and "wisenheimer." But, in fact, "wiseacre" came to English by a different route; it derived from the Middle Dutch "wijssegger" (meaning "soothsayer"), a modification of the Old High German "wīzzago." "Wiseacre" first appeared in English way back in the late 16th century, while the "insolent" sense of "wise" and the words formed from it are products of the 19th and 20th centuries. 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."
