Emily Dickinson Lexicon

LEV'EL, a. [Sax. læfel, id; W. llyvn, smooth, even, level, sleek, slippery; llyvelu, to level, to render uniform, to devise, invent, guess; llyvnu, to make smooth. This seems to be connected with llyvu, to lick. So like, D. gelyk, G. gleich, is smooth, even, level, equal, coinciding with Eng. sleek. The L. libella, libra, belong to this root; It. livella.]

1. Horizontal; coinciding with the plane of the horizon. To be perfectly lord, is to be exactly horizontal.
2. Even; flat; not having one part higher than another; not ascending or descending; as, a level plain or field; level ground; a level floor or pavement. In common usage, level is often applied to surfaces that are not perfectly horizontal, but which have no inequalities of magnitude.
3. Even with any thing else; of the same highth; on the same line or plane.
4. Equal in rank or degree; having no degree of superiority. Be level in preferments, and you will soon be as level in your learning. – Bentley.
