What does "ne" mean?

Ne: Not; never. [Obs.] He never yet no villany ne said. Chaucer. Note: Ne was formerly used as the universal adverb of negation, and survives in certain compounds, as never (= ne ever) and none (= ne one). Other combinations, now obsolete, will be found in the Vocabulary, as nad, nam, nil. See Negative, 2.
