n. An instrument for determining the plane of the horizon, or the plane perpendicular to the direction in which bodies fall under the action of gravity.n. An imaginary surface everywhere perpendicular to the plumb-line, or line of gravity, so that it might be the free surface of a liquid at rest.n. Hence Figuratively, degree of elevation as regards standing, condition, or action; a height reached or aimed at, from a social, intellectual, or moral point of view.n. An extent of land-surface approximately horizontal and unbroken by irregularities; a plain.n. The point-blank aim of a missile weapon, including the line of fire and the range or distance the missile is carried without deflection; hence, purpose; aim.n. In mining, a drift or nearly horizontal excavation made in opening a mine. Levels are run to connect shafts and winzes, so as to open and make ready for stoping a certain amount of ground. In a mine regularly opened on a permanent vein, the levels are usually from 60 to 100 feet apart, but vary in position with the varying richness of the lode.n. A leveling-instrument. See clinometer-level and leveling-instrument.Lying in or constituting a horizontal surface; not having one part higher than another; horizontally even or flat; not sloping: as, level ground; a level floor or pavement.Lying in such a surface that no work is gained or lost in the transportation of a particle from any one point of it to any other; equipotential.Existing or acting in the same plane or course; continuing without change of relative elevation; even with something else.With reference to color, especially in dyeing, even; unbroken; uniform.Equal in rank or degree.Well-aimed; direct; straight; in a right line; conformable.Steady; in equipoise.Well-balanced; of good judgment: as, a level head.Synonyms and Level, Flat, Even. In regard to the surface of land, flat is a depreciative word, indicating lowness or unattractiveness, or both; level conveys no slur, and is entirely consistent with beauty: as, flat marshes; level prairies. Flat is a rather more absolute word than level. That which is flat or level is parallel to the horizon; that which is even is free from inequalities: as, an even slope.To make horizontal; bring into a plane parallel to the horizon, as by the use of a leveling-instrument: as, to level a billiard-table.To reduce or remove inequalities of surface in; make even or smooth: as, to level a road or walk.To reduce or bring to the same height as something else; lay flat; especially, to bring down to the ground; prostrate.To reduce to equality of condition, state, or degree; bring to a common level or standing in any respect: as, to level ranks of society.To direct to an object, in a particular line, or toward a purpose; point or aim.To adapt; suit; proportion: as, to level observations to the capacity of children.In surveying, to find the level or the relative elevation of by observation or measurement.In dyeing, to make smooth and uniform. See level, adjective, 4.Synonyms To raze, destroy, demolish.To be in the same direction with something; be aimed.To point a weapon at the mark; take aim: as, he leveled and fired; hence, to direct a purpose; aim.To conjecture; attempt to guess.To accord; agree; suit.To work with a leveling-instrument; make the observations necessary for constructing a profile or vertical section of any line on the earth's surface, or for ascertaining the difference of elevation between two or more stations.A corruption of levy.n. The correction for level of an astronomical instrument; the deviation of its axis from exact horizontality.n. In landscape-gardening, one of the horizontal surfaces in which an irregular piece of land may be arranged. By the use of different levels the designer may place various features of his design above or below the eye.
