The word "sticklike" is a modern English compound adjective formed by combining two native Germanic elements. The first element, "stick," originates from the Old English sticca, which referred to a slender piece of wood, a concept with Proto-Germanic origins. The second element, "-like," descends from the Old English suffix -līc, derived from the noun līc (body, form), and has functioned for centuries to create adjectives meaning "having the form or character of." The compound logic is perfectly transparent: it literally means "having the form of a stick," directly describing a long, thin, and often rigid physical appearance. This straightforward morphological process of noun + suffix is a productive and common method for creating descriptive terms in English.
