You may be nauseous, I am just nauseated

[colliemommie]

Every time someone in pregnant complains about how "nauseous" she is, I can't help but laugh. I realize it seems to be a popular colloquial usage to use the word to describe feeling sick, but being popular does not make it right. I unilaterally revoke the Humpty Dumpty Law in this case. I don't care how much extra you pay "nauseous", it means "causing nausea", the same as "nauseating".

So, while I will not argue with anyone who claims she is "nauseous", I steadfastly remain merely nauseated.
