Word History

Etymology

probably borrowed from French, originally a word applied to the dark skin lesion associated with the cutaneous form of the disease, extended in the 18th century to the disease itself (also called charbon); earlier, "dark skin lesion, carbuncle," going back to Middle French antrac, borrowed from Late Latin anthrac-, anthrax, borrowed from Greek anthrak-, ánthrax "charcoal (burning or unlit, usually in plural), coal, dark red precious stone, dark skin lesion," probably of pre-Greek substratal origin

Note: In the sense "carbuncle, purulent skin lesion (of various origins)," anthrax has been in occasional use in English since Middle English (then attested as antrax, antrace). Regarding the origin of the Greek word, cf. andráchlē "warming pan, brazier," (with -d- for -th-) and kándaros glossed ánthrax by Hesychius (k- alternating with ø), features (along with the suffix -ak-) suggesting substratal origin (see Robert Beekes, Etymological Dictionary of Greek, Brill, 2010).
