Where does boldness come from?

1 Answer

From Middle English bold, bolde, bald, beald, from Old English bald, beald (“bold, brave, confident, strong, of good courage, presumptuous, impudent”), from Proto-West Germanic *balþ, from Proto-Germanic *balþaz (“strong, bold”), from Proto-Indo-European *bʰel-, *bʰlē- (“to bloat, swell, bubble”).
