Origin of floor
Word Origin for floor
Old English flor "floor, pavement, ground, bottom (of a lake, etc.)," from Proto-Germanic *floruz "floor" (cf. Middle Dutch and Dutch vloer, Old Norse flor "floor," Middle High German vluor, German Flur "field, meadow"), from PIE *plaros "flat surface" (cf. Welsh llawr "ground"), enlarged from *pele- (2) "flat, to spread" (see plane (n.1)).
Meaning "level of a house" is from 1580s. The figurative sense in legislative assemblies (as opposed to the platform) is first recorded 1774. Spanish suelo "floor" is from Latin solum "bottom, ground, soil;" German Boden is cognate with English bottom. Floor plan attested from 1867.
take the floor
Rise to speak formally to an assembled group, as in After that long introduction, the treasurer took the floor. This idiom uses floor in the sense of “right to speak,” in turn derived from its meaning as the part of the legislature from which members address the group. [c. 1800]
