plane

plane: English has five distinct planes, four of which are essentially the same word as plain. These come ultimately from Latin plānus, but preserve its ‘flat’ meanings rather than (like plain) its ‘clear’ meanings. Plane ‘flat surface’ [17] comes from Latin plānum, a noun use of the neuter form of the adjective; it is the plane from which aeroplane, and hence its abbreviation plane, were formed. Plane ‘carpenter’s smoothing tool’ [14] comes via Old French plane from late Latin plāna, a derivative of the verb plānāre ‘make level’, itself a derivative of plānus. Plane ‘flat’ [17] is an alteration of plain, on the model of French plan ‘flat’.

And plane ‘glide, soar’ [17] comes from French planer, a derivative of plan ‘level surface’ (the underlying notion being of a bird soaring with level wings). The odd man out is plane the tree-name [14], which comes via Old French plane and Latin platanus from Greek plátanos, a derivative of platús ‘broad’ (source of English place, plaice, and platypus) – the reference being to its broad leaves. Platanus probably also underlies English plantain, as applied to the banana-like vegetable.
=> piano, plain; place, plaice, plantain, plate, platypus

plane (n.1)

"flat surface," c. 1600, from Latin planum "flat surface, plane, level, plain," noun use of neuter of adjective planus "flat, level, even, plain, clear," from PIE *pla-no- (cognates: Lithuanian plonas "thin;" Celtic *lanon "plain;" perhaps also Greek pelanos "sacrificial cake, a mixture offered to the gods, offering (of meal, honey, and oil) poured or spread"), suffixed form of root *pele- (2) "to spread out; broad, flat" (cognates: Old Church Slavonic polje "flat land, field," Russian polyi "open;" Old English and Old High German feld, Middle Dutch veld "field"). Introduced (perhaps by influence of French plan in this sense) to differentiate the geometrical senses from plain, which in mid-16c. English also meant "geometric plane." Figurative sense is attested from 1850. As an adjective from 1660s.

plane (v.2)

"soar, glide on motionless wings," early 15c., from Old French planer "to hover (as a bird), to lie flat," from plan (n.)

plane (n.4)

"tree of the genus Platanus," late 14c., from Old French plane, earlier plasne (14c.), from Latin platanus, from Greek platanos, earlier platanistos "plane tree," a species from Asia Minor, associated with platys "broad" (see plaice (n.)), in reference to its leaves.
