Usage Discussion of NAUSEOUS

Those who insist that nauseous can properly be used only in sense 1 and that in sense 2 it is an error for nauseated are mistaken. Current evidence shows these facts: nauseous is most frequently used to mean physically affected with nausea, usually after a linking verb such as feel or become; figurative use is quite a bit less frequent. Use of nauseous in sense 1 is much more often figurative than literal, and this use appears to be losing ground to nauseating. Nauseated is used more widely than nauseous in sense 2.

Examples of NAUSEOUS

  1. The smell of gasoline makes me nauseous.
  2. I began to feel nauseous.
  3. Instead what they do is all sit together and feel really bad, and pray. Nobody does anything as nauseous as try to make everybody all pray together or pray aloud or anything, but you can tell what they're doing. —David Foster Wallace, Rolling Stone, 25 Oct. 2001
