The word "wormlike" is a transparent Modern English compound formed from two ancient Germanic roots. The first element, "worm," originates from the Old English wyrm, a term with a broad semantic range covering creeping or coiled creatures, from serpents to insects. This root can be traced back to the Proto-Indo-European base wer-, meaning "to turn, bend," which aptly describes the sinuous movement of such creatures. The second element, "-like," derives from the Old English noun līc, meaning "body" or "form," which evolved into a suffix denoting resemblance. The compound logic is perfectly literal: "having the form or characteristics of a worm." Its formation follows a common and productive English pattern for creating descriptive adjectives, directly linking the observable physical attributes of a worm to any entity that shares them.

Structure: worm + like - worm: From Old English wyrm, meaning "serpent, snake, dragon, insect." It is of Germanic origin, related to Latin vermis "worm." In this compound, it functions as the noun root specifying the object of resemblance. - like: From Old English līc "body, form" (in compounds), and gelīc "like, similar."
