We are confident that you won’t slip up or err in learning today’s word, despite its etymology. “Labile” was borrowed into English from French and can be traced back (by way of Middle French “labile,” meaning “prone to err”) to the Latin verb “labi,” meaning “to slip or fall.” Indeed, the first sense of “labile” in English was “prone to slip, err, or lapse,” but that usage is now obsolete. Other “labi” descendants in English include “collapse,” “elapse,” “prolapse,” and simply “lapse.”
