determiner & pronoun
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 be used only with uncountable things (less money; less time). With countable things, it is incorrect to use less: thus, less people and less words should be corrected to fewer people and fewer words. See also few (usage).
