Etymology: "Abyssus" is the Latin form of a Greek word, "ábussos," built from the negative prefix "a-" ("without") and "bythós," meaning "bottom" or "depth," so the whole thing literally means "without a bottom." Greek writers used it of a bottomless or unfathomable depth, and that sense passed straight into Latin, where "abyssus" carried the same idea of an immeasurable gulf. The Greek root "bythós" traces back to a Proto-Indo-European root for "deep," which is why the word connects to an ancient stock of words for depth, though its real story is the one that unfolded in Greek and Latin. English borrowed the Latin form directly, and the word has kept its original picture: something so deep you cannot find its floor. Its most famous setting is the biblical and theological sense of the abyss as the bottomless pit, a sense that makes the word's etymology feel almost literal.
