Nauseous vs. Nauseated: Usage Guide

Those who insist that nauseous can properly be used only to mean "causing nausea" and that its later "affected with nausea" meaning 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 to mean "causing nausea or disgust" is much more often figurative than literal, and this use appears to be losing ground to nauseating. Nauseated is used more widely than nauseous when referring to being affected with nausea.

Frequently Asked Questions

Is one nauseous or nauseated?

Some usage guides have held that there should be a strict distinction between nauseous and nauseated, with the first word meaning "causing nausea or disgust" and the second one meaning "affected with nausea." However, nauseous has been in widespread enough use for both of these senses that this distinction is now quite blurred. Nauseous may mean either "causing nausea" or "affected with nausea"; nauseated, on the other hand, is restricted in meaning to "affected with nausea; feeling disgust."

What is the verb for nauseous?

The verb form of nauseous is nauseate, meaning "to affect with nausea or disgust." It comes from the Latin word meaning "seasickness, nausea," which itself may be traced back to the Greek word for "sailor" (nautēs).
