The English word ghost continues Old English gást, from a hypothetical Common Germanic *gaistoz. It is common to West Germanic, but lacking in North and East Germanic (the equivalent word in Gothic is ahma, Old Norse has andi m., önd f.). The pre-Germanic form would have been *ghoisdo-s, apparently from a root denoting "fury, anger", cognate to Sanskrit hedas "anger", reflected in Old Norse geisa "to rage". The Germanic word is recorded as masculine only, but likely continues a neuter s-stem. The original meaning of the Germanic word would thus have been an animating principle of the mind, in particular capable of excitation and fury (compare óðr). In Germanic paganism, "Germanic Mercury", and the later Odin, was at the same time the conductor of the dead and the "lord of fury" leading the Wild Hunt.
