knife-like

The compound adjective "knife-like" is a transparent modern English formation following a productive Germanic pattern for creating descriptive terms. The first element, "knife," originates from the Old English cnīf, a common Germanic term for a cutting tool, whose deeper origins are uncertain but may be related to a root meaning "to pinch" or "to cut." The second element, "-like," derives from the Old English noun līc, meaning "body" or "form," which evolved into a suffix denoting resemblance. The compound's logic is straightforward and literal: it directly combines the concrete object with the suffix of similarity to create a figurative descriptor for anything sharp, slender, or incisive in nature.
