Old English lǣssa, of Germanic origin; related to Old Frisian lēssa, from an Indo-European root shared by Greek loisthos 'last'
In standard English less should only be used with uncountable things (less money, less time). With countable things it is incorrect to use less (less people and less words); strictly speaking, correct use is fewer people and fewer words. See also few (usage).
