Etymology: "Levatores" is the plural of "levator", a term for a muscle that lifts or raises a body part. The singular comes from New Latin "levātor", meaning "one that lifts or raises", and the Latin verb "levare" ("to lift") is the same root that gave English the word "lever". The two are doublets: they descend from one Latin source but reached English by different routes, so a physical bar used to pry things up and a muscle that hoists a body part share a common ancestor. The Latin noun "levator" was built from the verb "levare", which in turn came from "levis", meaning "light" in weight. The underlying idea is making something less heavy or easier to move, which fits both a pry bar that lifts a load and a muscle that raises a limb. Anatomists in early modern and later centuries drew on Latin agent endings like this one to name muscles by their function, so "levator" follows the same pattern as many other muscle names built from Latin roots.
