Word Origin and History for Hades

1590s, from Greek Haides, in Homer the name of the god of the underworld, of unknown origin. Perhaps literally "the invisible" [Watkins]. The name of the god transferred in later Greek writing to his kingdom. Related: Hadal (adj.), 1964; Hadean.



Old English had "person, individual, character, individuality; condition, state, nature; sex, race, family, tribe;" see -hood. Obsolete after 14c. Cognate with Old Saxon hed "condition, rank, Old Norse heiðr "honor, dignity," Old High German heit, Gothic haidus "way, manner."
