quite a few

Old English feawe (plural; contracted to fea) "few, seldom, even a little," from Proto-Germanic *faw-, from PIE root *pau- (1) "few, little" (cf. Latin paucus "few, little," paullus "little," parvus "little, small," pauper "poor;" Greek pauros "few, little," pais (genitive paidos) "child;" Latin puer "child, boy," pullus "young animal;" Oscan puklu "child;" Sanskrit potah "a young animal," putrah "son;" Old English fola "young horse;" Old Norse fylja "young female horse;" Old Church Slavonic puta "bird;" Lithuanian putytis "young animal, young bird"). Always plural in Old English.

Phrase few and far between attested from 1660s. Unusual ironic use in quite a few "many" (1883), earlier a good few (1828). The noun is late 12c., fewe, from the adjective.
