The core difference lies in whether you are describing the feeling itself (nausea), the state of experiencing the feeling (nauseated), or the thing that causes the feeling (nauseous).
Understanding the nuances between "nausea," "nauseated," and "nauseous" can clarify descriptions of feeling unwell. While related, these terms have distinct technical meanings based on their usage.
Nausea: The Feeling Itself
- Nausea is the noun. It refers to the unpleasant, uneasy sensation in the stomach that often precedes vomiting.
- The reference mentions that the root word, nausea, is a Latin word that specifically refers to seasickness, highlighting its origin tied to a feeling of sickness.
How to Use Nausea:
- Used as a noun to name the condition or sensation.
- Often followed by a verb describing its presence or impact.
Examples:
- Nausea can be a side effect of this medication.
- He experienced intense nausea after the boat ride.
- Nausea is a common symptom of motion sickness.
Nauseated: Experiencing the Feeling
- Nauseated is an adjective that describes the state of a person experiencing nausea.
- As stated in the reference, the word nauseated means "to be affected with nausea" or "to feel sick to your stomach."
How to Use Nauseated:

Nauseous: Causing the Feeling

Understanding "Feeling Nauseous"
While technically "nauseous" describes something causing sickness, the phrase "feeling nauseous" is very commonly used to mean "feeling nauseated" or "feeling sick to the stomach." Although this usage deviates from the stricter definition provided in the reference, it is widely understood and accepted in everyday language.
- Technically Correct: "I am nauseated." or "I feel nauseated."
- Commonly Used (though technically describing the cause): "I am nauseous." or "I feel nauseous."
Summary Table
| Term | Part of Speech | What it Describes | Strict Meaning Example | Common Usage Example (for the person) |
|---|---|---|---|---|
| Nausea | Noun | The feeling or condition | "He experienced nausea." | N/A |

Practical Takeaways
- To be precise and follow the technical definitions (as outlined in the reference):
- Use nausea to refer to the feeling itself.
- Use nauseated to describe a person feeling sick.
- Use nauseous to describe something that makes you feel sick.
- In everyday conversation, saying you "feel nauseous" is very common and easily understood, even if "feel nauseated" is technically more accurate for describing your own state.
Understanding these distinctions, especially the technical difference between nauseated (feeling sick) and nauseous (causing sickness) as highlighted by the reference, helps in clearer communication, particularly in formal or medical contexts.
