Without ghosts; free from ghosts or ghostly manifestations.
From 'ghost' + '-less' suffix (meaning without, as in 'homeless' or 'fearless'). A descriptive term for places or states devoid of supernatural activity.
The '-less' suffix is one of English's most useful tools for negation—'ghostless' actually has clearer meaning than its opposite because 'ghostful' isn't a real word; we'd say 'haunted' instead.
