Wight refers to a supernatural being or spirit, often associated with folklore and mythology. In various cultures, wights are depicted as the souls of the dead or as nature spirits. They can be benevolent or malevolent, depending on the story or tradition. In modern usage, particularly in fantasy literature like George R.R. Martin's "A Song of Ice and Fire", wights are often portrayed as reanimated corpses controlled by a more powerful entity. This concept has gained popularity in various media, including television adaptations like HBO's "Game of Thrones".
