| plane 1 (plān) n.
[Latin plānum, flat surface, from neuter of plānus, flat; see pelə-2 in Indo-European roots. N., sense 4, short for aeroplane.] 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. |

[Middle English planen, to glide, soar, from Old French planer, from plain, flat, level; see plain.] |

Any tree of the genus Platanus. Note: The Oriental plane (Platanus orientalis) is a native of Asia. It rises with a straight, smooth, branching stem to a great height, with palmated leaves, and long pendulous peduncles, sustaining several heads of small close-sitting flowers. The seeds are downy, and collected into round, rough, hard balls.

Plane chart, Plane curve. See under Chart and Curve. Plane figure, a figure all points of which lie in the same plane. If bounded by straight lines it is a rectilinear plane figure, if by curved lines it is a curvilinear plane figure. Plane geometry, that part of geometry which treats of the relations and properties of plane figures. Plane problem, a problem which can be solved geometrically by the aid of the right line and circle only. Plane sailing (Naut.), the method of computing a ship's place and course on the supposition that the earth's surface is a plane. Plane scale (Naut.), a scale for the use of navigators, on which are graduated chords, sines, tangents, secants, rhumbs, geographical miles, etc. Plane surveying, surveying in which the curvature of the earth is disregarded; ordinary field and topographical surveying of tracts of moderate extent. Plane table, an instrument used for plotting the lines of a survey on paper in the field. Plane trigonometry, the branch of trigonometry in which its principles are applied to plane triangles.Plane
Plane\, n. [F. plane, L. plana. See Plane, v. & a.]1. (Geom.) A surface, real or imaginary, in which, if any two points are taken, the straight line which joins them lies wholly in that surface; or a surface, any section of which by a like surface is a straight line; a surface without curvature. 2. (Astron.) An ideal surface, conceived as coinciding with, or containing, some designated astronomical line, circle, or other curve; as, the plane of an orbit; the plane of the ecliptic, or of the equator. 3. (Mech.) A block or plate having a perfectly flat surface, used as a standard of flatness; a surface plate. 4. (Joinery) A tool for smoothing boards or other surfaces of wood, for forming moldings, etc. It consists of a smooth-soled stock, usually of wood, from the under side or face of which projects slightly the steel cutting edge of a chisel, called the iron, which inclines backward, with an apperture in front for the escape of shavings; as, the jack plane; the smoothing plane; the molding plane, etc. Objective plane (Surv.), the horizontal plane upon which the object which is to be delineated, or whose place is to be determined, is supposed to stand. Perspective plane. See Perspective. Plane at infinity (Geom.), a plane in which points infinitely distant are conceived as situated. Plane iron, the cutting chisel of a joiner's plane. Plane of polarization. (Opt.) See Polarization. Plane of projection. (a) The plane on which the projection is made, corresponding to the perspective plane in perspective; -- called also principal plane. (b) (Descriptive Geom.) One of the planes to which points are referred for the purpose of determining their relative position in space. Plane of refraction or reflection (Opt.), the plane in which lie both the incident ray and the refracted or reflected ray.Plane
Plane\, v. t. [imp. & p. p. Planed; p. pr. & vb. n. Planing.] [Cf. F. planer, L. planare, fr. planus. See Plane, a., Plain, a., and cf. Planish.]1.

plane (1)
"flat surface," 1604, from L. plantum "flat surface," properly neut. of adj. planus "flat, level, plain, clear," from PIE *pla-no- (cf. Lith. plonas "thin;" Celtic *lanon "plain;" perhaps also Gk. pelanos "sacrificial cake, a mixture offered to the gods, offering (of meal, honey, and oil) poured or spread"), suffixed form of base *pele- "to spread out, broad, flat" (cf. O.C.S. polje "flat land, field," Rus. polyi "open;" O.E., O.H.G. feld, M.Du. veld "field"). Fig. sense is attested from 1850. The verb meaning "soar, glide on motionless wings" is first recorded 1611, from M.Fr. planer (16c.), from L. planum on notion of bird gliding with flattened wings. Of boats, etc., "to skim over the surface of water" it is first found 1913.
plane (3)
"tool for smoothing surfaces," 1349, from O.Fr. plane, earlier plaine (14c.), from L.L. plana, from planare "make level," from L. planus "level, flat" (see plane (1)). The verb meaning "to make smooth" is c.1320, from O.Fr. planer (12c.), from L.L. planare.
plane (4)
"tree of the genus Platanus," 1382, from O.Fr. plane, earlier plasne (14c.), from L. platanus, from Gk. platanos, earlier platanistos "plane tree," a species from Asia Minor, associated with platys "broad," in reference to its leaves (see place (n.)). Applied since 1778 in Scotland and northern England to the sycamore, whose leaves somewhat resemble those of the true plane tree.
