From Middle English blunder, blonder (“disturbance, strife”), from the verb blundren, blondren, which itself is partly from Middle English blondren, a frequentative form of blonden, blanden ("to mix; mix up"; see blend); and partly from blundren, a frequentative form of blunden (“to stagger; stumble”), from Old Norse blunda (“to shut the eyes; doze”). Cognates include Swedish dialectal blundra (“to act blindly or rashly”), Danish blunde (“to blink”) or blunde (“to take a nap”).
