O.E. folc "common people, men, tribe, multitude," from P.Gmc. *folkom (cf. O.Fris. folk, M.Du. volc, Ger. Volk "people"), from P.Gmc. *fulka-, perhaps originally "host of warriors;" cf. O.N. folk "people," also "army, detachment;" and Lith. pulkas "crowd," O.C.S. pluku "division of an army," both believed to have been borrowed from P.Gmc. Some have attempted, without success, to link the word to Gk. plethos "multitude;" L. plebs "people, mob," populus "people" or vulgus. Superseded in most senses by people. Colloquial folks "people of one's family" first recorded 1715. Folksy "sociable, unpretentious" is 1852, U.S. colloquial, from folks + -y.
