Wight
Wight is an obsolete word for a human or other intelligent being. It is used now only to give an impression of archaism and mystery, for example in the works of J. R. R. Tolkien. Probably inspired by Scandinavian folklore (see below), Tolkien also used the word to denote human-like creatures, such as elves or ghosts ("wraiths"). It is akin to other words of Old English origin such as were and world. Many Tolkien-inspired works of fantasy fiction and roll-playing games (such as Dungeons and Dragons) use the term as the name of an undead creature similar to a ghost.
Also from the same Germanic root:
In Scandinavian folklore the Vetter, or VÃÂättar ("wights") are elves, and correspond roughly to gnomes when they are benevolent, and to goblins when they are not. A tomte is a benevolent vÃÂätte who can live among people, but only shows himself when they are asleep.
The IllvÃÂätte is a goblin.
In Norse mythology, the LandvÃÂættir ("land-wights") were the resident spirits of specific farms and wild places. The term includes beings which are equivalent to fairies, to the Greek nymphs, or to other earthen beings. In Icelandic sagas, Vikings (when not at war) took off the carved dragons from the bows of their Longships before making land, so as not to frighten the landvÃÂættir and incur bad luck from them.
The Isle of Wight is an island off the south coast of England.
