Definition:
(n.)

(n.) A horizontal line or plane; that is, a straight line or a plane which is tangent to a true level at a given point and hence parallel to the horizon at that point; -- this is the apparent level at the given point.
(n.) An approximately horizontal line or surface at a certain degree of altitude, or distance from the center of the earth; as, to climb from the level of the coast to the level of the plateau and then descend to the level of the valley or of the sea.
(n.) Hence, figuratively, a certain position, rank, standard, degree, quality, character, etc., conceived of as in one of several planes of different elevation.
(n.) A uniform or average height; a normal plane or altitude; a condition conformable to natural law or which will secure a level surface; as, moving fluids seek a level.
