Etymology

It is inherited from Middle English flor,[2][3] inherited from Old English flōr (“floor, pavement, ground, bottom of a lake”),[4][2] from Proto-Germanic *flōruz,[4][2][5] the source also of Dutch vloer, Middle High German vluor (German Flur “field, meadow”) and Old Norse flórr “floor of a cow stall”.[2][4] Outside Germanic it is cognate with Old Irish lár and Welsh llawr “ground, floor”,[2][5] and with Latin plānus “level”, the source of plain;[2][3] Etymonline takes it to Proto-Indo-European *pele- (“flat; to spread”).[4] The verb is from the noun.[2][4] The spelling floor is not recorded before about 1390.[2]

Earliest recorded meaning

Old English flōr is found about 725 in Beowulf,[2] and the OED's first example of the surface of a room is from about 888.[6] The bottom of a lake or sea is a floor before 1000.[6]

Semantic evolution

A level or story of a house is from the 1580s.[4] In legislative assemblies the floor where members sit and speak, as opposed to the platform, is from 1774,[4] hence to have the floor, “to have the right to speak”.[7] The verb, “to furnish with a floor”, is from the early 15th century[4] (implied in flooring in 1387).[2] “To knock down to the floor” is from the 1640s,[4][6] and the figurative “to puzzle, confound” is first recorded in Coleridge's Table Talk (1830).[2][4] In mid-19th-century university slang to floor a paper was to do it thoroughly and successfully.[4] Floor it, “to press hard on the accelerator”, is by 1986.[4] Compounds include floor-plan (1794), floor-board (1787) and floor-walker (1862).[4]
