Etymology: Strongyloid comes from "Strongylus", a genus name, plus the suffix "-oid", meaning "resembling" or "like". "Strongylus" is itself built from the Greek "strongylos", meaning "round" or "rounded", a fitting description of these slender, cylindrical worms. Naturalists gave the genus its name by taking the Greek adjective and adapting it into a Latinised scientific form. The suffix "-oid" comes from Greek "eidos", meaning "form" or "shape", and it has long been attached to scientific names to mean "resembling" the thing named. So a strongyloid is, in effect, something that looks like a member of the Strongylus group. The word is a technical coinage from classical roots, built for zoologists rather than inherited from ancient speakers. Because the word names a whole family of worms rather than one species, its meaning stays tied to the classification. Its parts are transparent to anyone who knows the Greek, which is why it reads as a descriptive label rather than a common name.
