Etymology: Lumbricoides is the name of a genus of parasitic roundworms, and its root is a plain Latin word that has nothing to do with worms as such. The Latin "lumbricus" meant "earthworm," and the suffix "-oides" comes from Greek "eidos," meaning "form" or "resemblance," so the name literally means "earthworm-like." Scientists took the Latin word for the common earthworm and added the Greek ending to describe a parasite that looked like one. The genus name was coined by Carl Linnaeus, the Swedish botanist who standardized the naming system for living things. He applied it to the human roundworm, Ascaris lumbricoides, and it has stuck as the scientific label for that species ever since. The choice reflects how Linnaeus and his contemporaries drew on classical languages to name new discoveries, reaching back to Latin and Greek for descriptive terms.
