ambrosia  The Geek and Roman gods were in many ways like mortal men, but they had the major distinction of immortality, which came as a result of their eating-habits. Ambrosia, the food of the gods, and nectar their drink, had the property of preventing death. Greek ambrosia, literally "immortality", is a derivative of ambrotos, "immortal". the prefix a-(sometimes known as the alpha privative) indicates negation, as does the related Latin in- or im-. And -mbrotos is close kin to Latin mortalis.SupeSite/X-Space官方站3Qcb

Q(O6U7Da/Q+eb0         Nectar comes from Greek nektar, which may have a similar etymological meaning of 'overcoming death', if it is derived from the Greek root nek-'death'. This root is reflected in several English words of classical derivation, such as necrosis and necrohilia. But the origin of the Greek term is uncertain.
