Synonym discussion

Sense: noun/1

Floor, ground, and flooring all relate to flat surfaces, but they are not interchangeable. Floor is the indoor walking surface inside a building: 'The cat is sleeping on the kitchen floor.' Ground is the outdoor surface of the earth: 'The keys fell on the ground outside.' You cannot say 'on the ground' when you mean inside a room, nor 'on the floor' when you mean bare earth. Flooring refers to the material or covering used to make a floor (wood, tile, vinyl): 'We chose bamboo flooring for the living room.' Unlike floor, flooring is an uncountable noun and describes a type of covering rather than a specific surface. For 'level of a building', floor is the everyday word (third floor, top floor), while story/storey is used for counting levels in descriptions of a building's size ('a five-story building'). Level is more neutral and can apply to floors, parking decks, or even non-building contexts. For natural bottom surfaces (ocean floor, forest floor), bottom is the general word for the lowest part of anything (a box, a lake, a cup), while seabed is the technical term restricted to the sea.

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

Floor comes from Old English 'flōr', which goes back to a Proto-Germanic root '*flōraz' meaning a flat, level surface. This root is related to the word 'field' (both come from the idea of something spread out flat). The meaning 'level of a building' developed in late Middle English, and the figurative sense of 'minimum limit' (price floor, wage floor) appeared in American English during the 20th century.
