Coleridge.
3. Any faint shadowy semblance; an unsubstantial image; a phantom; a
glimmering; as, not a ghost of a chance; the ghost of an idea.
Each separate dying ember wrought its ghost upon the floor.
Poe.
4. A false image formed in a telescope by reflection from the surfaces
of one or more lenses.
Ghost moth (Zoˆl.), a large European moth (Hepialus humuli); so called
from the white color of the male, and the peculiar hovering flight; --
called also great swift. -- Holy Ghost, the Holy Spirit; the Paraclete;
the Comforter; (Theol.) the third person in the Trinity. -- To give up
or yield up the ghost, to die; to expire.
And he gave up the ghost full softly.
Chaucer.
