Ancient Greek ἀλώπηξ /alɔ́ːpɛːks/; this ends up as Modern /aleˈpu/ via the Hellenistic variant ἀλωπά, somehow: Λεξικό της κοινής νεοελληνικής.
In English, the Ancient word for fox has given us alopecia: Hair loss
The origin of this usage is because this animal sheds its coat twice a year, or because in ancient Greece foxes often lost hair because of mange.
