Etymology: "Saphenas" is the plural of "saphena," the name for the two large superficial veins of the leg. The Latin term comes from a medieval Arabic word, "ṣāfin," which described a vein that lies hidden beneath the skin, and that Arabic word in turn derives from Hebrew "ṣōfēn," meaning "hiding." The name thus records a physical observation: these veins are not visible in the way many others are, and the concealment in the Hebrew root is what the anatomists kept. The word passed into medieval Latin, where scholars used it to name the vessels, and it was carried into anatomical terminology from there. Its Arabic and Hebrew ancestry is why the term sounds unlike the Greek and Latin names that fill most of anatomy.
