Etymology: "Superciliaries" is simply the plural of "superciliary," which is the adjective (and in this case used as a noun) for anything relating to the eyebrows. The base word comes from the Latin "supercilium," meaning "eyebrow," built from "super" ("above") and "cilium" ("eyelid" or "eyelash"). The same "cilium" root gives English the word "cilia," the tiny hair-like structures found on cells. Because "superciliary" is a formal anatomical term, it is most often seen in medical and scientific writing, where it describes structures such as the superciliary arches, the bony ridges above the eye sockets. The plural form, "superciliaries," follows the Latin-derived pattern used for many English nouns and adjectives of this type.
