[first posted October 22, 2004] In an earlier post, I referred to this collection of useful usage articles by James Thurber. On the question of using “bad” or “badly” within a sentence like “I feel bad(ly),” Thurber advises not to use either word.

There is, of course, a special problem presented by the type of person who looks well even when he doesn’t feel well, and who is not likely to be believed if he says he doesn’t feel well. In such cases, the sufferer should say, “I look well, but I don’t feel well.” While this usage has the merit of avoiding the troublesome words “bad” and “badly,” it also has the disadvantage of being a negative statement. If a person is actually ill, the important thing is to find out not how he doesn’t feel, but how he does feel. He should state his symptoms more specifically—“I have a gnawing pain here, that comes and goes,” or something of the sort. There is always the danger, of course, that one’s listeners will cut in with a long description of how they feel; this can usually be avoided by screaming.
