The non-physical part of a person which is the seat of emotions and character; the soul.
The non-physical part of a person regarded as their true self and is capable of surviving physical death or separation.
The non-physical part of a person manifested as an apparition after their death; a ghost.
A spirit is a ghost or supernatural being.
Spirit short for Holy Spirit.
We use the word ghost and spirit interchangeably but there really is a strong difference between them.
According to the late Hans Holzer, professor of Parapsychology and
writer of 119 books on the subject,
"Ghosts are similar to psychotic
human beings, incapable of
reasoning for themselves. …
Spirits on the other hand are the surviving personalities of all of us
who pass through the door of
death in a relatively
normal fashion."

We learn from him that ghosts are tied to the location of their death, usually a sudden or tragic one, and
they often don't realize that they are dead. In most cases, they have "unfinished business" as the deceased
person does not accept the way in which they died. The simplest form of unfinished business can be as
innocent as a person being attached so strongly to their home that they cannot leave it behind and pass over.
They are known as "caretakers" and want to stay to make sure the building is being taken care of properly
by future owners and also to their approval.
Spirits are not tied to one place. It is believed that spirits are discarnate entities, meaning that they are the
soul that has survived when a person dies and no longer has a physical body in which to reside. They are free
to move from one dimension to another and can return to us at free will. Often it is just a genuine, emotional tie
to a loved one, such as wanting a family member to know that a deceased relative is okay,
that can be the cause of a visit by a spirit.
