Etymology: "Levelnesses" is the plural of "levelness," a noun meaning the quality of being level. The base word "level" entered English in the 14th century from Old French "livel," itself from Vulgar Latin "*libellum," a diminutive of Latin "libra," meaning balance or scale. The idea of a level surface comes from the balance: a plumb line and a horizontal bar, or a liquid settling evenly in a vessel, were the physical tests of flatness. The suffix "-ness," from Old English "-nes," turns an adjective into a noun for a quality, so "levelness" names the state of being level. The plural "levelnesses" is rare, used when speaking of several distinct instances or degrees of evenness, such as the different flatnesses of several floors or fields.
