4. (n.) Hence, figuratively, a certain position, rank, standard, degree, quality, character, etc., conceived of as in one of several planes of different elevation.

5. (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.

6. (n.) An instrument by which to find a horizontal line, or adjust something with reference to a horizontal line.

7. (n.) A measurement of the difference of altitude of two points, by means of a level; as, to take a level.

10. (a.) Coinciding or parallel with the plane of the horizon; horizontal; as, the telescope is now level.

11. (a.) Even with anything else; of the same height; on the same line or plane; on the same footing; of equal importance; -- followed by with, sometimes by to.
