Etymology: Hirudinean is a term from zoology for the leeches, the group of segmented worms that includes the bloodsucking species. It is built from the Latin "hirudo," meaning leech, which is the same root behind the medical term "hirudin," the anticoagulant protein found in the saliva of medicinal leeches. The suffix "-ean" is the ordinary English adjective ending, so the word means "of or relating to leeches," and it is used both as an adjective and as a noun for a member of the group. The Latin "hirudo" is itself connected to the verb "haurire," meaning to draw out or drain, which fits the leech's habit of drawing blood. Since the word is a scientific formation built from classical roots, it was coined by naturalists rather than inherited from ancient speakers, and the Romans themselves would have used "hirudo" simply for the animal.
