ghost: [OE] In Old English times, ghost was simply a synonym for ‘spirit’ or ‘soul’ (a sense preserved in Holy Ghost); it did not acquire its modern connotations of the ‘disembodied spirit of a dead person appearing among the living’ until the 14th century. However, since it has been traced back to Indo-European *ghois- or *gheis-, which also produced Old Norse geisa ‘rage’, Sanskrit hédas ‘anger’, and Gothic usgaisjan ‘terrify’, it could well be that its distant ancestor denoted as frightening concept as the modern English word does.

The Old English form of the word was gāst, which in Middle English became gost; the gh- spelling, probably inspired by Flemish gheest, first appeared at the end of the 15th century, and gradually established itself over the next hundred years.
