Did you know?

Errant has a split history. It comes from Anglo-French, a language in which two confusingly similar verbs with identical spellings ("errer") coexisted. One errer meant "to err" and comes from the Latin errare, meaning "to wander" or "to err." The second errer meant "to travel," and traces to the Latin iter, meaning "road" or "journey." Both "errer" homographs contributed to the development of "errant," which not surprisingly has to do with both moving about and being mistaken. A "knight-errant" travels around in search of adventures. Cowboys round up "errant calves." An "errant child" is one who misbehaves. (You might also see "arrant" occasionally - it's a word that originated as an alteration of "errant" and that usually means "extreme" or "shameless.")
