語源 1

From 中期英語 bad, badde (“wicked, evil, depraved”), of uncertain origin. Perhaps a shortening of 古期英語 bæddel (“hermaphrodite”) (for loss of -el compare 中期英語 muche from 古期英語 myċel, and 中期英語 wenche from 古期英語 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 中期英語, 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).

使用する際の注意点

When placed after the main verb, use of bad as an intensifier is often more accepted than badly. Compare:

 I bad need to eat.  I badly need to eat.

 I need bad to eat.  I need badly to eat.

 I need to eat bad.  I need to eat badly.

It is also common in certain set expressions, such as bad off, which may be perceived as an extended form of the adjective bad rather than the adverb bad ~ badly modifying the adjective off.

   • 1876, The Gloucester Journal, Oct. 7, 1876, reported in A. Gregory, “Gloucestershire Dialect,” Notes and Queries, 5th ser., 6, 148 (1876‑10‑28): 346

     A curious specimen of Gloucestershire dialect came out in an assault case heard by the Gloucester court magistrates on Saturday. One of the witnesses, speaking of what a girl was doing at the time the assault took place, said she was ‘badding’ walnuts in a pigstye. The word is peculiarly provincial: to ‘bad’ walnuts is to strip away the husk. The walnut, too, is often called a ‘bannut,’ and hence the old Gloucestershire phrase, ‘Come an’ bad the bannuts.’
