What is the equivalent term for ghost in literary contexts?

In literary contexts, the term "ghost" often refers to a spirit or an apparition of someone who has died. This aligns perfectly with the term "apparition," which is used to describe a visible spirit or phantom, typically appearing in a supernatural or eerie manner.

The connection between ghosts and apparitions is rooted in folklore and literature, where ghosts are portrayed as the souls of the deceased appearing to the living, often to convey messages or fulfill unfinished business. This term captures the essence of the ghostly presence that contributes to the atmosphere and themes in literary works.

In contrast, the other terms—apprehension, animosity, and antidote—do not convey the same spectral or supernatural qualities associated with a ghost. Apprehension relates to fear or anxiety, animosity refers to hostility or resentment, and antidote means a remedy to counteract a poison or a problem, none of which convey the same meaning as "ghost" in a literary sense.
