I wrote a blog post in November 2007 about “Nauseous” vs. “Nauseated”.

I recently heard an actress on a TV drama say that she felt nauseous when she should have said that she felt nauseated.

She made me think again about the two words.

And I realized something: Saying “nauseous” when one should say “nauseated” instead is consistent with my “Devolution toward Simpler” linguistic hypothesis.

Many Americans say “nauseous” as if it had only two syllables, as in NAW-SHUHS, instead of pronouncing all three syllables, as in NAW-ZEE-UHS.

Either way, it is simpler to say the two- or three-syllable “nauseous” than it is to say the four-syllable “nauseated”.
