badとは

語源 1

From Middle English bad, badde (“wicked, evil, depraved”), of uncertain origin. Perhaps a shortening of 古期英語 bæddel (“hermaphrodite”) (for loss of -el compare Middle English muche from 古期英語 myċel, かつ Middle English wenche from 古期英語 wenċel), from bædan (“to defile”), from Proto-Germanic *bad- (compare Old High German pad (“hermaphrodite”)). Alternatively, a loan from Old Norse into Middle English, compare Norwegian bad (“effort, trouble, fear”, neuter noun), East Danish bad (“damage, destruction, fight”, neuter noun), from the Proto-Germanic noun *bada- (Kroonen, Etymological Dictionary of Proto-Germanic, s.v. *badōjan-).
