Etymology: Metastrongyloidea is a modern scientific coinage, not an ancient word. It was built in the nineteenth or twentieth century from Greek elements: "meta-" meaning "after" or "beyond," "strongylos" meaning "round," and "-oidea," the standard suffix for zoological superfamily names, which derives from Greek "eidos," meaning "form" or "likeness." The name points to the nematodes' rounded, thread-like bodies, and the prefix "meta-" reflects its placement in classification as a grouping that sits alongside or beyond the closely related Strongyloidea. The "-oidea" ending follows the same convention used across animal taxonomy, so a reader who recognises it in other superfamily names can read the pattern at once. The root "strongyl-" is also the stem behind the genus name "Strongylus," a group of nematodes first named in the early nineteenth century, which is where the taxonomic family of roundworms draws its base.
