[Latin plānum, flat surface, from neuter of plānus, flat. N., sense 4, short for AEROPLANE.]

planeness plane'ness n.

WORD HISTORY   The plane in which we fly is properly named for a very important element of its structure-the wing that keeps it in the air. But the story behind this name is slightly complicated. To begin with, plane in the sense of "winged vehicle," first recorded in April 1908, is a shortened form of aeroplane. In June of that year plane appeared in a quotation from the London Times that mentioned one of the Wright brothers. Aeroplane, first recorded in 1866, is made up of the prefix aero-, "air, aviation," and the word plane, referring to the structure designed to keep an air vehicle aloft. Originally the plane in such contexts was imagined as flat, hence the choice of the word plane; in practice this surface must curve slightly in order to work. The word aeroplane for the vehicle is first found in 1873. The first recorded appearance of the form airplane in our current sense, which uses air- instead of aero-, is found in 1907. An American flies in an airplane while a Briton still travels in an aeroplane, but both can catch a plane.

plane, in mathematics, flat surface of infinite extent but no thickness. An example of a plane, or more exactly of a bounded portion of a plane, is the surface forming one face, or side, of a cube. A plane is determined, or defined, by any of the following: (1) three points not in a straight line; (2) a straight line and a point not on the line; (3) two intersecting lines; or (4) two parallel lines. Two straight lines in space do not usually lie in the same plane. For a given plane in space, a line can either lie outside and parallel to it, intersect the plane in a single point, or lie entirely in the plane; if more than one point of a straight line lies in the plane, then the entire line must lie in the plane.

n

An ideal flat surface that intersects solid bodies, extends uniformly in various directions (horizontally, vertically, laterally, or any relative combination thereof), and is determined by the position in space of three points.

Body in anatomical position with the median, sagittal, horizontal, and frontal planes noted. (Fehrenbach/Herring, 2002)
