Etymology
From Middle English bolt, from Old English bolt, from Proto-West Germanic *bolt, from Proto-Germanic *bultaz, perhaps from Proto-Indo-European *bʰeld- (“to knock, strike”). Compare Lithuanian beldu (“I knock”), baldas (“pole for striking”). Akin to Dutch and West Frisian bout, German Bolz or Bolzen, Danish bolt, Swedish bult, Icelandic bolti.
The association of thunder and lightning with 'bolts' is found back into prehistory in many cultures, at least in Eurasia. It comes from the long-standing widespread belief that lightning was caused by bolts, darts, or stones hurtling down from the sky to the earth. This belief was still regarded as commonplace until at least 1929.
From Middle English bulten, from Anglo-Norman buleter, Old French bulter (modern French bluter), from a Germanic source originally meaning "bag, pouch" cognate with Middle High German biuteln (“to sift”), from Proto-Germanic *buzdô (“beetle, grub, swelling”), from Proto-Indo-European *bʰūs- (“to move quickly”). Cognate with Dutch buidel.
* As an English surname, from the noun bolt, for a maker of bolts, or a nickname for a short and heavy person.
* Also as an English surname, variant of Bold.
* As a Dutch, north/Low German and Danish surname, from the old Germanic name Baldo, derived from the adjective bold and related to the above. Compare Boldt.
