Where it comes from
From Late Middle English redarguen, redargue (“to defeat (someone) in an argument; to rebuke, reprove”), from Middle French redarguer and Old French redargüer (“to disprove, refute; to accuse, blame; to rebuke, reprove”) (modern French rédarguer), and from their etymon Latin redarguere (“to disprove, refute”) (compare Late Latin redarguere (“to rebuke, reprove”)), the present active infinitive of redarguō (“to disprove, refute; to contradict”), from red- (a variant of re- (prefix meaning ‘again’)) + arguō (“to assert, declare; to clarify, make plain; to prove, show; to accuse, charge with; to censure, rebuke, reprove; to blame; to denounce as false”) (possibly ultimately from Proto-Indo-European *h₂erǵ- (“argent, white; glittering”), in the sense of casting light on something to make it clear). Doublet of argue.
