  • noun Synonyms Ghost, Shade, Apparition, Specter, Phantom, Phantasm. Ghost is the old word for the disembodied spirit, especially as appearing to man: as, the ghost of Hamlet's father; the ghost of Banquo. Shade is a soft and poetic word for ghost: as, the shade of Creüsa appeared to Æneas. An apparition is a ghost as appearing to sight, perhaps suddenly or unexpectedly; it may also be a fancied appearance, while a ghost is supposed to be real: as, Jupiter made a cloud into an apparition of Juno; Macbeth saw an apparition of a dagger; the witches showed him an apparition of a crowned child. A specter is an alarming or horrifying preternatural personal appearance, having less individuality, perhaps, than a ghost or shade, but more than an apparition necessarily has. A phantom has an apparent, not a real, existence; it differs from a phantasm in emphasizing the unreality simply and in representing a single object, while phantasm emphasizes the deception put upon the mind, and may include more than one object.
