late 14c., from Latin Æthiops "Ethiopian, negro," from Greek Aithiops, long supposed in popular etymology to be from aithein "to burn" + ōps "face" (compare aithops "fiery-looking," later "sunburned").
Who the Homeric Æthiopians were is a matter of doubt. The poet elsewhere speaks of two divisions of them, one dwelling near the rising, the other near the setting of the sun, both having imbrowned visages from their proximity to that luminary, and both leading a blissful existence, because living amid a flood of light; and, as a natural concomitant of a blissful existence, blameless, and pure, and free from every kind of moral defilement. [Charles Anthon, note to "The First Six Books of Homer's Iliad," 1878]
old name for Ethiopia, 1630s, from Modern Latin Abyssinia, from Arabic Habasah, the name for the region, said to be from Amharic hbsh "mixed" or Arabic habash "mixture," in reference to the different races dwelling there. In 1920s-30s popular as a slang pun for the parting salutation "I'll be seeing you." Related: Abyssinian (1620s; as a breed of domestic cat, 1876). In early use also Abyssine.
