ghost writer media n. one who writes on behalf of another who is officially credited with authorship. The role is easier to acknowledge in certain genres of writing and tends to be associated with popular cultural cultural forms, especially where individuals famous for exploits in ostensibly non-literary fields (e.g. sporting endeavour, screen-acting, entertainment, and so on) are commissioned to write an autobiography or newspaper column. The autobiographies of Ronald Reagan, Doris Day and Sophia Loren were penned by ghost writers. mmo
