Etymology: The sense "clear and direct" grew out of a much more physical idea. "Incisive" entered English in the late Middle Ages meaning "cutting" or "penetrating," the way a blade goes into something. It was borrowed from Medieval Latin "incīsīvus," built from "incīdere," "to cut into," which itself combined "in-" (into) with "caedere" (to cut). The Latin verb is also the source of the English "incision," so the two words are close relatives. The shift from blade to mind happened gradually. A remark that cuts through confusion, or an analysis that gets straight to the heart of a problem, is described in the same terms as a knife that goes straight through cloth. The sense of "clear and direct" follows naturally from that image: a penetrating thought leaves nothing hanging around the edges.
