Nauseated and nauseous both relate to feeling sick, but careful English gives them different jobs. Traditionally, “nauseated” means you feel sick, while “nauseous” means something makes you feel sick. In modern everyday speech, people often use “nauseous” for both. This simple guide will explain the difference with easy examples, a memory trick, and a mini quiz.
What Is the Simple Difference?
The simple difference is this: nauseated means feeling sick in your stomach, as if you might vomit. Nauseous, in its traditional meaning, means causing nausea — a smell or a sight that makes others feel sick. In modern use, many people also say “I feel nauseous” to mean “I feel sick”, and that is now widely accepted. So for exams, use nauseated for the feeling and nauseous for the cause.
Nauseated: The Feeling Word
Nauseated (pronounced “NAW-zee-ay-tid”) is an adjective meaning you feel sick and uncomfortable in your stomach. It describes the person who is suffering, not the thing causing the sickness.
- The rough sea made her feel nauseated.
- He felt nauseated after eating too much cake.
- The smell of the hospital made me nauseated.
Nauseous: The Causing Word
Nauseous (pronounced “NAW-shuhs”) is an adjective that traditionally means causing nausea — something so unpleasant that it makes people feel sick. In modern everyday English, it is also commonly used to mean “feeling sick”.
- The nauseous smell of the rotten fish filled the room.
- The nauseous sight of the accident made him turn away.
- “I feel nauseous” is common today, though “nauseated” is more precise.
The Easy Trick to Remember
- Nauseated ends with “-ated” — like “I am affected”. It describes how you feel: affected by sickness.
- Nauseous ends with “-ous” — like “poisonous”. Just as something poisonous causes harm, something nauseous causes sickness.
- People are nauseated; smells are nauseous — the person feels it, the smell causes it.
- Say it as a rhyme: “I feel nauseated and low, when the nauseous smell starts to grow.”
