Etymology
The term 'roundworm' is a transparent Modern English compound, formed by directly combining two native Germanic words. 'Round' derives from Old English 'rund' or 'rond', related to the concept of a circle or ring, which itself can be traced back to a Proto-Indo-European root meaning 'to run' or 'to flow', perhaps evoking a circular course. 'Worm' comes from Old English 'wyrm', meaning serpent or dragon, originating from a Proto-Indo-European root for 'to turn' or 'to twist', describing the creature's sinuous movement. The compound name 'roundworm' is a descriptive anatomical reference to the cylindrical, non-segmented body shape of nematodes, distinguishing them from flatworms (platyhelminths) and segmented worms (annelids).
