flat

flat: [14] The Old English word for ‘flat’ was efen ‘even’, and flat was not acquired until Middle English times, from Old Norse flatr. This came from a prehistoric Germanic *flataz, source also of German platt ‘flat’. And *flataz probably goes back to an Indo-European *pelə -, *plā-, denoting ‘spread out flat’, from which came Sanskrit prthūs ‘broad’, Greek platūs ‘broad’ (source of English place, plaice, plane [the tree], and platypus), Latin plānus ‘flat’ (whence English plane and plain ‘unadorned’), and also English place, plaice, plant, and flan. Flat ‘single-storey dwelling’ [19] is ultimately the same word, but it has a more circuitous history.

It is an alteration (inspired no doubt by the adjective flat) of a now obsolete Scottish word flet ‘interior of a house’, which came from a prehistoric Germanic *flatjam ‘flat surface, floor’, a derivative of the same source (*flataz) as produced the adjective.
=> flan, flatter, floor, place, plaice, plane, platypus

flat (adj.)

c. 1300, "stretched out (on a surface), prostrate, lying the whole length on the ground;" mid-14c., "level, all in one plane; even, smooth;" of a roof, "low-pitched," from Old Norse flatr "flat," from Proto-Germanic *flata- (cognates: Old Saxon flat "flat, shallow," Old High German flaz "flat, level," Old English flet (for which see flat (n.)), Old High German flezzi "floor"), from PIE *plat- "to spread" (source of Greek platys "broad, flat;" see plaice (n.)). From c. 1400 as "without curvature or projection."
