Preta is a Sanskrit word that carries different meanings in Hinduism and Buddhism. In Hinduism, it refers to a ghost or spirit that has suffered a premature death, while in Buddhism, it represents a hungry and wandering spirit. Other synonyms for this word include Peta, Petari, and Pitri, depending on the cultural context. These words are often used interchangeably to describe the same concept of a restless or suffering spirit that requires help from the living. In Hinduism, the term Bhoot or Bhuta is also used to describe ghosts. In Buddhism, the term Gaki or Gakido is sometimes used in place of Preta.
