What is the origin of alopecia?

Doctors use "alopecia" to refer to various forms of hair loss, including "alopecia areata," a sudden loss of hair in patches that involves little or no inflammation. It may surprise you to learn that the word ultimately derives from "alōpēx," the Greek word for "fox," but the connection makes sense if you think of a fox who is afflicted with mange, a disease with symptoms that include, among other things, loss of hair. Middle English speakers borrowed the Latin word alopecia, which comes from "alōpekia," a Greek term that can be translated as "mange on foxes."

Word History

Etymology

Middle English allopicia, allopucia "hair loss," borrowed from Medieval Latin allōpicia, allōpitia "baldness, mange," going back to Latin alōpecia "bald patch on the head (from a skin disease)," borrowed from Greek alōpekía "bald spot" (Aristotle), "disease causing hair loss" (Galen), original sense perhaps "sarcoptic mange (affecting foxes and other canids)," from alōpek-, alṓpēx "fox" + -ia -ia entry 1; alṓpēx probably going back to dialectal Indo-European *h2lōpeḱ-/*h2lōpēḱ- "small canid, fox" (whence, besides Greek, Armenian ałuēs "fox") and *h2leupēḱ- or *h2loupēḱ- (whence Sanskrit lopāśáḥ "small canid [as a jackal or fox]," Middle Persian rōpās, rōpāh "fox," Khotanese rrūvāsa- "jackal," Ossetic (Iron dialect) rubas, ruvas "fox")

Note: An initial element *(h2)lop-, close to the Greek, Armenian, and Indo-Iranian forms but with a short o, is apparently reflected in Celtic *lop-erno-, whence Old Welsh leuyrn, leuirn "foxes" (from *lou̯ern-ī with vowel affection; cf. Modern Welsh llewyrn, tân llewyrn "foxfire"), Breton louarn "fox," and Lithuanian lãpė "fox," Latvian lapsa. The long o in alṓpēx could perhaps be taken as a reflection of an original nominative *h2lōp-s, but the diphthong in the Indo-Iranian etymon remains unexplained. The element *(h2)lop- has been compared with *u̯l̥p- "small carnivore" proposed as the source of Latin vulpēs, volpēs "fox" (see vulpine), Lithuanian vilpišỹs "wildcat" and other words, but no unifying etymon can be readily reconstructed. If related, the set of "fox" forms are perhaps traces of a non-Indo-European Wanderwort acquired by Indo-European branches at different times and places.
