blunder

Inherited from Middle English blundren, blondren (verb) and blunder, blonder (“disturbance, strife”), from the verb; partly from Middle English blondren, a frequentative form of Middle English blonden, blanden ("to mix; mix up"; corresponding to blend +‎ -er); and partly from Middle English blundren, a frequentative form of Middle English blunden (“to stagger; stumble”), from Old Norse blunda (“to shut the eyes; doze”).

Cognates include Norwegian blunda (“to shut the eyes; doze”), dialectal Swedish blundra (“to act blindly or rashly”), Danish blunde (“to blink”) or blunde (“to take a nap”), Icelandic blunda (“to nap; doze”). Related to English blind.
