1. flat

   Horizontal signifies in the direction of or parallel to the horizon. For practical purposes level and horizontal are identical, tho level, as the more popular word, is more loosely used of that which has no especially noticeable elevations or inequalities; as, a level road. Flat, according to its derivation from the Anglo-Saxon flet, a floor, applies to a surface only, and, in the first and most usual sense, to a surface that is horizontal or level in all directions; a line may be level, a floor is flat; flat is also applied in a derived sense to any plane surface without irregularities or elevations, as a picture may be painted on the flat surface of a perpendicular wall. Plane applies only to a surface, and is used with more mathematical exactness than flat. The adjective plain, originally the same word as plane, is now rarely used except in the figurative senses, but the original sense appears in the noun, as we speak of "a wide plain." We speak of a horizontal line, a flat morass, a level road, a plain country, a plane surface (especially in the scientific sense). That which is level may not be even, and that which is even may not be level; a level road may be very rough; a slope may be even.

   Synonyms:
   even, horizontal, level, plain, plane

   Antonyms:
   broken, hilly, inclined, irregular, rolling, rough, rugged, slanting, sloping, uneven
