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.
