From Middle English bad, badde (“wicked, evil, depraved”), of uncertain origin. Perhaps a shortening of Old English bæddel (“hermaphrodite”) (for loss of -el compare Middle English muche from Old English myċel, and Middle English wenche from Old English wenċel), or at least related to it and/or to bǣ̆dan (“to defile”), compare Old High German pad (“hermaphrodite”). Alternatively, perhaps 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 *badą, whence also Proto-Germanic *badōną (“to frighten”), Old Saxon undarbadōn (“to frighten”), Norwegian Nynorsk bada (“to weigh down, press”); ultimately from Proto-Indo-European *bʰedʰ- (“to bend, press, push, oppress”). False cognate of Persian بد (bad).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
