What's the difference between elevation and levation?
Elevation
Definition:
(n.) The act of raising from a lower place, condition, or quality to a higher; -- said of material things, persons, the mind, the voice, etc.; as, the elevation of grain; elevation to a throne; elevation of mind, thoughts, or character.
(n.) Condition of being elevated; height; exaltation.
(n.) That which is raised up or elevated; an elevated place or station; as, an elevation of the ground; a hill.
(n.) The distance of a celestial object above the horizon, or the arc of a vertical circle intercepted between it and the horizon; altitude; as, the elevation of the pole, or of a star.
(n.) The angle which the style makes with the substylar line.
(n.) The movement of the axis of a piece in a vertical plane; also, the angle of elevation, that is, the angle between the axis of the piece and the line o/ sight; -- distinguished from direction.
(n.) A geometrical projection of a building, or other object, on a plane perpendicular to the horizon; orthographic projection on a vertical plane; -- called by the ancients the orthography.

Levation
Definition:
(n.) The act of raising; elevation; upward motion, as that produced by the action of a levator muscle.
