Nauseous vs. Nauseated–Which Is She?

Let’s have a quick look at the commonly confused nauseous vs nauseated.

My dear friend just had major surgery in another city. Texting me to let me know how she is, her husband wrote, “She’s nauseous a lot.”

But is she nauseous or nauseated? What do you think?

Word sticklers distinguish between nauseous and nauseated. Because my friend was an English major in college and is now well known in the publishing world, I will tell you that she would describe herself as nauseated–not nauseous. 

Although many people use the words interchangeably, traditionalists see distinctions:

Nauseous

Nauseous is an adjective. It means “causing nausea” or “sickening.”

Examples:

A nauseous gas is escaping from the pipe.  

I could not bear the nauseous description of the torture. 

My friend is not sickening or causing anyone nausea; therefore, according to language purists, she is not nauseous. 

Nauseated

Nauseated is an adjective and a verb (nauseate, nauseated, etc.). It means “to feel or cause to feel nausea” and “to feel or cause to feel loathing or disgust.” 

Examples:

She is nauseated because of the medication. (This is my friend’s condition. She is feeling nausea.)

His nauseating rant went on for 20 minutes. 

The constant curves on the mountain highway nauseate Victoria. 

Nauseous vs Nauseated

Here’s what The Chicago Manual of Style says about nauseous and nauseated:

“Whatever is nauseous, traditionally speaking, induces a feeling of nausea–it makes us feel sick to our stomachs. To feel sick is to be nauseated. Although the use of nauseous to mean nauseated may be too common to be called an error anymore, strictly speaking it is poor usage. Because of the ambiguity in nauseous, the wisest course may be to stick to the participial adjectives nauseated [for my friend] and nauseating [for my friend’s medication].”

Garner’s Modern English Usage puts it this way:

Nauseous (inducing nausea) for nauseated (experiencing nausea) is becoming so common that to call it an error is to exaggerate. Even so, careful writers tend to be sickened [nauseated?] by the slippage and to follow the traditional distinction in formal writing. That is, what is nauseous makes one feel nauseated.

My mum brought these to the hospital on my first day of treatment, and the memory still makes me nauseous. – The Guardian

IN A tunnel beneath Stuttgart railway station, your correspondent was startled and slightly nauseated by a large poster advertising a sandwich filled with Fleischkäse. – The Economist
