a mental representation of some haunting experience; "he looked like he had seen a ghost"; "it aroused specters from his past"
a writer who gives the credit of authorship to someone else
the visible disembodied soul of a dead person
a suggestion of some quality; "there was a touch of sarcasm in his tone"; "he detected a ghost of a smile on her face"
move like a ghost; "The masked men ghosted across the moonlit yard"
haunt like a ghost; pursue; "Fear of illness haunts her"
write for someone else; "How many books have you ghostwritten so far?"
