Etymology

Middle English awne, going back to late Old English agene (accusative plural) "awns," Old English ægnan (plural) "chaff, sweepings," going back to Germanic *aganō-, *ahanō (whence also Old High German agana "awn, chaff, straw," Old Norse ǫgn, plural agnar "chaff, husks," Gothic ahana "chaff"), going back to Indo-European *h2eḱ-on- (whence also Old Prussian ackons "awn" and perhaps Latin agna "ear of grain," Greek akont-, ákōn "javelin, dart"), derivative of *h2eḱ- "sharp, pointed" — more at edge entry 1
