At the A1 level, you are just starting to learn how to describe how you feel. While 'náuseoso' might be a bit advanced, you can understand it as a way to say you feel sick to your stomach. You probably already know 'me siento mal' (I feel bad) or 'me duele el estómago' (my stomach hurts). 'Náuseoso' is a more specific word for that feeling you get before you might vomit. Think of it like the English word 'nauseous'. At this level, you should focus on the phrase 'Estoy náuseoso' (I am nauseous) or 'Estoy náuseosa' if you are a woman. It is a useful word if you need to tell a doctor or a teacher that you don't feel well. Just remember that in Spanish, we use the verb 'estar' (to be) for feelings that change, like being sick. You wouldn't use 'ser' because you aren't a nauseous person all the time! It is just a temporary feeling. You might also hear this word if you are traveling on a bus or a boat and someone else feels sick. Even if you don't use it yourself yet, recognizing it will help you understand when others are talking about their health.
At the A2 level, you are expanding your vocabulary to include more specific physical sensations. 'Náuseoso' is an excellent word to add to your health-related vocabulary. You can now use it to describe why you can't eat something or why you need to sit down. For example, 'No quiero comer, estoy un poco náuseoso' (I don't want to eat, I'm a bit nauseous). You are also learning about gender agreement, so remember: 'Él está náuseoso' but 'Ella está náuseosa'. At this level, you might also start to see this word used to describe things that cause the feeling, like 'un olor náuseoso' (a sickening smell). It is important to distinguish this from 'mareado' (dizzy). If your head is spinning, use 'mareado'. If your stomach is upset, use 'náuseoso'. You might encounter this word in simple stories or in dialogues at a pharmacy. Practicing the sentence 'Me siento náuseoso' will help you communicate more clearly in everyday situations involving health or travel discomfort.
As a B1 learner, you are expected to handle more complex situations and describe experiences in more detail. 'Náuseoso' is a key adjective for this level because it allows you to move beyond basic descriptions of illness. You should be comfortable using it with verbs like 'sentirse' and 'ponerse'. For example, 'Me puse náuseoso al ver la escena del accidente' (I got nauseous upon seeing the accident scene). At this level, you are also introduced to the written accent rules; 'náuseoso' is an 'esdrújula' word, meaning the stress is on the third-to-last syllable, so it always needs an accent on the 'á'. You should also begin to recognize the figurative use of the word. While it primarily describes a physical state, it can also describe something morally disgusting, like a corrupt act. You will see this word in news articles, medical brochures, and literature. Understanding the difference between 'náuseoso' and its stronger cousin 'nauseabundo' (stinking/repulsive) will help you refine your descriptions. You should be able to explain your symptoms to a doctor using this word to ensure you receive the correct advice or medication.
At the B2 level, you should have a firm grasp of the nuances of 'náuseoso'. You are expected to use it accurately in both literal and figurative contexts. You can use it to describe a wide range of stimuli, from 'medicamentos náuseosos' (nauseating medicines) to 'comentarios náuseosos' (sickening comments). You should also be able to use it in different tenses and moods. For example, 'Si hubiera comido eso, me habría sentido náuseoso' (If I had eaten that, I would have felt nauseous). At this stage, you should be aware of the register of the word; it is slightly more formal and precise than 'asqueroso' (gross). You can also use it to describe the atmosphere of a place, such as a 'náuseoso ambiente de hipocresía' (a sickening atmosphere of hypocrisy). Your ability to distinguish between 'náuseoso', 'mareado', 'asqueado', and 'repugnante' should be well-developed, allowing you to choose the exact word that fits the intensity and nature of the situation you are describing. You will encounter 'náuseoso' in more sophisticated texts, including editorials and modern fiction, where it is used to evoke a strong physical or emotional response in the reader.
At the C1 level, your use of 'náuseoso' should be natural and precise. you understand its place within a vast web of synonyms and can deploy it to achieve specific rhetorical effects. You might use it in a literary analysis to describe the 'náuseoso existencialismo' (existential nausea) found in certain philosophical works, or in a political critique to describe the 'náuseoso espectáculo de la demagogia' (the sickening spectacle of demagoguery). You are sensitive to the word's ability to trigger a visceral reaction in the listener or reader. Your grammatical control is perfect, including the correct placement for emphasis: 'el náuseoso hedor de la traición' (the sickening stench of betrayal). You also understand the historical and etymological roots of the word, linking it to the Greek 'nausia' (ship-sickness), which adds depth to your understanding of its use in maritime or travel contexts. At this level, you can use 'náuseoso' to add a layer of sensory detail to your writing, making your descriptions more immersive and impactful. You are also able to discuss the subtle differences between 'náuseoso' and other high-level adjectives like 'aborrecible' or 'execrable' in a professional or academic setting.
At the C2 level, you have complete mastery over the word 'náuseoso' and its various connotations. You can use it with effortless precision in any context, from a highly technical medical discussion to a sophisticated piece of creative writing. You understand the word's potential for irony and sarcasm, and you can use it to craft complex metaphors. For example, you might describe a particularly cloying and insincere piece of praise as 'un elogio náuseoso'. You are fully aware of how the word's meaning has evolved and how it is used across different Spanish-speaking regions. You can identify and utilize its most formal and its most visceral applications. In your own writing, you use 'náuseoso' not just to describe a feeling, but to evoke an atmosphere or to underscore a moral judgment with physical weight. You are also capable of explaining the linguistic nuances of the word to others, including its relationship with nouns like 'náusea' and verbs like 'nausear'. Your command of the word is such that it is no longer just a vocabulary item, but a versatile tool in your extensive linguistic repertoire, used to convey the finest shades of meaning and emotion.

náuseoso in 30 Seconds

  • An adjective meaning 'nauseous' or 'nauseating', used to describe physical sickness or things that cause disgust.
  • Commonly paired with 'estar' for temporary feelings and 'ser' for inherent sickening qualities of objects.
  • Crucial for medical, travel, and descriptive contexts, emphasizing a specific type of stomach-centered malaise.
  • Must agree in gender and number with the noun it modifies (náuseoso, náuseosa, náuseosos, náuseosas).

The Spanish adjective náuseoso is a word that English speakers will find quite intuitive because it shares the same Latin root as the English word 'nauseous'. At its core, it describes a physiological state of discomfort in the stomach that often precedes vomiting. However, its usage in Spanish is nuanced and requires an understanding of how it interacts with verbs like estar and sentirse. In the Spanish-speaking world, describing one's health is a common part of daily social interaction, and being able to accurately convey this specific type of malaise is essential for B1 learners who are moving beyond simple 'me duele' (it hurts) descriptions.

Physical Sensation
The primary use of náuseoso is to describe the actual feeling of being sick to one's stomach. It is frequently triggered by motion sickness, food poisoning, or pregnancy. When a person says 'Estoy náuseoso', they are reporting a subjective internal state that is often accompanied by paleness or cold sweats.

El viaje en barco fue tan movido que pasé todo el tiempo sintiéndome náuseoso y sin ganas de comer nada.

Beyond the physical, náuseoso can also describe something that causes nausea, although Spanish often prefers the word nauseabundo for objects that are inherently disgusting. When used to describe an object or a situation, náuseoso implies that the thing in question has the power to turn your stomach. This could be a smell, a sight, or even a particularly gruesome story. In literary contexts, authors use this word to evoke a visceral reaction in the reader, painting a picture of something so repulsive that it affects the body's equilibrium.

Metaphorical Disgust
In a more abstract sense, the word can be applied to moral or ethical situations. A 'náuseoso' act of corruption or a 'náuseoso' display of arrogance suggests that the behavior is so foul it makes the observer feel physically ill. This is a common device in political commentary and high-level journalism.

Ese olor náuseoso que salía de la alcantarilla nos obligó a cerrar todas las ventanas de la casa inmediatamente.

Understanding the cultural weight of health descriptions in Spain and Latin America is vital. People tend to be very descriptive about their physical state. Using náuseoso instead of just saying 'me siento mal' provides a level of specificity that helps doctors, family members, or friends understand exactly what you are going through. It is a word of discomfort, yes, but also a word of precision. In medical settings, a patient might be asked if they feel náuseoso specifically to differentiate between a stomach issue and a general fever or headache. This distinction is crucial for diagnosis and treatment.

Agreement and Gender
Remember that as an adjective, it must agree with the noun it modifies. A woman would say 'Estoy náuseosa', while a group of people would say 'Estamos náuseosos'. If referring to a collection of things (like odors, which are 'olores'), it becomes 'olores náuseosos'.

La paciente se despertó de la anestesia sintiéndose algo náuseosa, lo cual es un efecto secundario bastante común.

La película incluía unas escenas tan explícitas y náuseosas que varios espectadores tuvieron que abandonar la sala de cine.

In summary, náuseoso is a versatile adjective that bridges the gap between physical sensation and descriptive disgust. Whether you are describing a rough ferry ride across the Mediterranean or a repulsive smell in a city alley, this word allows you to communicate the specific intensity of your reaction. It is a key building block for intermediate Spanish learners who want to express complex physical and emotional states with clarity and impact.

Mastering the use of náuseoso involves understanding the grammatical framework of Spanish adjectives and the specific verbs they pair with. The most common way you will encounter this word is in conjunction with the verb estar. Because feeling nauseous is almost always a temporary state, estar is the grammatically correct choice over ser when referring to a person's condition. If you say 'Soy náuseoso', you are essentially saying that your personality or inherent nature is sickening, which is likely not what you mean! Instead, 'Estoy náuseoso' tells the listener that right now, in this moment, you are experiencing that unpleasant stomach sensation.

With Verbs of Feeling
Verbs like sentirse (to feel) and ponerse (to become/get) are also frequent partners. 'Me siento náuseoso' is a very natural way to express the onset of the feeling. 'Me puse náuseoso al ver la sangre' describes a change in state triggered by an external event.

Cada vez que leo en el coche, empiezo a sentirme náuseoso después de solo cinco minutos.

When describing objects, náuseoso usually follows the noun it modifies. For example, 'un ambiente náuseoso' (a sickening atmosphere) or 'un sabor náuseoso' (a nauseating taste). In these cases, the adjective describes a characteristic of the object. While nauseabundo is often used for smells, náuseoso is perfectly acceptable to describe anything that provokes that physical reaction. The word must also match the gender and number of the noun. For instance, 'las medicinas náuseosas' (the nauseating medicines) shows the feminine plural agreement.

Position and Intensity
Placing the adjective after the noun is the standard, neutral position. However, in poetic or highly emphatic speech, you might see it before the noun: 'el náuseoso olor de la derrota' (the sickening smell of defeat). This adds a layer of drama and intensity to the description.

La comida tenía un aspecto tan náuseoso que nadie en la mesa se atrevió a probar ni un bocado.

In medical or formal reports, you might see the word used in a more clinical way. 'El paciente presenta un cuadro náuseoso' (The patient presents a nauseous condition). Here, it functions as a formal descriptor of symptoms. It is also used in the context of side effects for medication: 'efectos náuseosos secundarios' (nauseating side effects). For a B1 learner, being able to use the word in these varied contexts—from casual conversation about a car ride to explaining symptoms to a pharmacist—is a significant step toward fluency.

Adverbial Phrases
Sometimes you might want to modify the intensity. You can use 'un poco náuseoso' (a bit nauseous), 'bastante náuseoso' (quite nauseous), or 'extremadamente náuseoso' (extremely nauseous). These modifiers help convey the severity of the feeling.

Después de la operación, es normal que te sientas un poco náuseoso debido a los efectos de la anestesia general.

No soporto ese perfume; tiene un aroma náuseoso que me revuelve el estómago cada vez que lo huelo.

Finally, consider the difference between náuseoso and mareado. While mareado means dizzy or lightheaded, náuseoso specifically refers to the stomach. Often they go together ('estoy mareado y náuseoso'), but being precise about which sensation you are feeling is key to effective communication in Spanish. By practicing these sentence patterns, you will become comfortable using náuseoso in any situation that calls for it.

The word náuseoso occupies a specific niche in the Spanish language, sitting between everyday speech and more formal or descriptive language. You are most likely to hear it in three primary environments: medical settings, travel contexts, and descriptive storytelling. In a clinic or hospital, a doctor or nurse will frequently use this word to assess a patient's symptoms. It is a standard term in the medical lexicon, used to describe a state that is more specific than just 'malestar' (discomfort). You might hear a nurse ask, '¿Se siente náuseoso o tiene dolor abdominal?' (Do you feel nauseous or do you have abdominal pain?). In this context, the word is clinical, precise, and necessary for accurate diagnosis.

Travel and Motion
Another common place to hear this word is during travel, particularly involving boats, planes, or winding mountain roads. Spanish-speaking countries like Spain, Mexico, or Colombia have diverse terrains where 'mareo' (motion sickness) is common. You might hear a fellow traveler say, 'El movimiento de las olas me está poniendo náuseoso'. It's a relatable, shared experience that often sparks conversations about remedies like ginger or specialized wristbands.

En el pequeño avión que cruzaba los Andes, casi todos los pasajeros se sentían náuseosos por la turbulencia.

In the realm of media and literature, náuseoso is used to create a strong sensory impact. In news reports about environmental disasters, such as oil spills or waste mismanagement, journalists often describe 'olores náuseosos' (nauseating smells) to emphasize the severity of the pollution. Similarly, in crime novels or horror stories, authors use the word to describe gruesome scenes or the physical reaction of a character to a horrific discovery. It’s a word that evokes a physical response in the reader, making the description more vivid and visceral.

Social and Political Critique
You will also encounter this word in opinion pieces or social media debates where someone wants to express extreme disapproval. A politician's lie or a celebrity's scandalous behavior might be described as 'náuseoso'. In this figurative sense, the word communicates that the action is so morally bankrupt that it causes a physical sense of revulsion.

El artículo de opinión describía el nivel de corrupción en la ciudad como algo simplemente náuseoso.

In everyday casual Spanish, while 'náuseoso' is used, you might also hear people say 'tengo náuseas' (I have nausea) or 'me dan ganas de vomitar' (it makes me want to vomit). However, 'náuseoso' remains the standard adjective. If you are watching a Spanish-language drama or movie, listen for it during scenes of illness or intense emotional distress. It is a word that carries a lot of weight and is never used lightly. Because it describes such a strong and specific sensation, hearing it immediately signals to the listener that the situation is serious or the reaction is extreme.

Product Labels and Warnings
Finally, look for this word on the back of medicine bottles or chemical cleaners. Warnings often state that a product may cause a 'estado náuseoso' if inhaled or ingested. This is a practical, real-world application of the word that every learner should be aware of for their own safety.

La etiqueta de advertencia decía que el producto podía provocar un efecto náuseoso si se usaba en lugares sin ventilación.

Al entrar en la habitación cerrada, nos recibió un olor náuseoso que delataba que algo se había podrido.

In conclusion, náuseoso is a word that lives in the overlap of the physical and the descriptive. By listening for it in these specific contexts—the doctor's office, the travel vlog, the news report, and the medicine label—you will begin to see how it functions as a precise tool for expressing intense discomfort and revulsion in the Spanish language.

Learning to use náuseoso correctly involves navigating a few common pitfalls that English speakers often encounter. The most frequent mistake is the confusion between ser and estar. As mentioned before, because feeling nauseous is usually a temporary state, you must use estar. If you say 'Soy náuseoso', you are describing an inherent, permanent quality of yourself—essentially saying 'I am a sickening person'. Unless you are trying to be incredibly self-deprecating or humorous, always stick with estar náuseoso or sentirse náuseoso to describe your current health status.

Confusion with 'Mareado'
Another common error is using 'náuseoso' when you actually mean 'mareado'. While they often happen at the same time, they are different sensations. 'Mareado' refers to dizziness, vertigo, or lightheadedness (your head is spinning). 'Náuseoso' refers specifically to your stomach feeling sick. If you tell a doctor you are 'náuseoso' but you actually feel like the room is spinning, you might lead them to the wrong diagnosis.

Error común: Decir 'Soy náuseoso' en lugar de 'Estoy náuseoso' cuando te sientes mal del estómago.

A third mistake is the confusion between náuseoso and nauseabundo. While they are related, nauseabundo is much stronger and almost always refers to something external that causes extreme disgust, like a rotting carcass or a filthy sewer. While you can describe a smell as 'náuseoso', 'nauseabundo' is the more common and evocative choice for that context. Using 'náuseoso' to describe a person who is actually vomiting might also be a slight understatement; in that case, people often use more direct verbs like 'vomitar' or 'trasbocar' (in some regions).

Spelling and Accents
The spelling of 'náuseoso' can be tricky for English speakers. Many forget the written accent on the 'á'. In Spanish, every word that has the stress on the third-to-last syllable (esdrújula) must have a written accent. Forgetting this accent is a common written error that can change the rhythm and even the perceived level of your Spanish proficiency.

No confundas: 'un olor náuseoso' (sickening) con 'una persona náuseosa' (a person feeling sick).

Finally, some learners try to use 'náuseoso' to mean 'annoying' or 'boring', similar to how 'sick' or 'sickening' can sometimes be used colloquially in English. This does not translate directly. If something is annoying, use 'molesto'; if it's boring, use 'aburrido'. 'Náuseoso' almost always retains its connection to physical or moral revulsion. Using it to mean 'boring' would be very confusing for a native speaker. Avoid these common traps, and your use of this adjective will be much more natural and effective.

False Friends and Cognates
While 'náuseoso' and 'nauseous' are cognates, the English 'nauseous' is often used to mean 'nauseated'. In Spanish, 'náuseoso' can mean both, but the verb phrase 'tener náuseas' is often preferred for the state of feeling sick. Don't over-rely on the adjective when a verb might be more common.

Es un error pensar que náuseoso se puede usar para decir que una película es aburrida; se usa para algo que da asco.

Recuerda: 'El paciente está náuseoso' es correcto, 'El paciente es náuseoso' suena a insulto.

By keeping these distinctions in mind—especially the ser/estar rule and the difference between physical dizziness and stomach sickness—you will avoid the most frequent errors and communicate your symptoms or observations with the precision of a native speaker.

When you want to describe feeling sick or something being disgusting in Spanish, náuseoso is just one tool in a very large shed. Depending on the intensity and the context, there are several other words you might choose to be more precise. For example, if you want to emphasize the cause of the nausea, especially a foul smell, nauseabundo is your best bet. It carries a stronger connotation of rotting or filth. While a medicine might be náuseoso (making you feel sick), a pile of garbage is nauseabundo.

Asqueroso vs. Náuseoso
Asqueroso is perhaps the most common alternative. It translates to 'gross' or 'disgusting'. While náuseoso is somewhat clinical, asqueroso is much more informal and emotional. You might call a dirty bathroom asqueroso, but you'd describe the feeling it gives you as náuseoso. They are two sides of the same coin: the cause (asqueroso) and the effect (náuseoso).

Ese callejón es asqueroso y el olor es tan nauseabundo que me hace sentir náuseoso.

Another important distinction is with mareado. As discussed, mareado means dizzy. If you are on a boat, you are likely both mareado and náuseoso. However, if you stand up too quickly and the room spins, you are only mareado. Using the correct word helps people know if they should give you a chair (for dizziness) or a bucket (for nausea). In some Latin American countries, people also use the word asqueado to mean 'disgusted' in a more general or moral sense, similar to being 'fed up' with something.

Repugnante and Repulsivo
These words are synonyms for something that causes a strong rejection. Repugnante is often used for behavior or sights that are morally or physically offensive. It is a 'harder' word than náuseoso and suggests a deeper level of loathing. 'Un crimen repugnante' sounds much more serious than 'un crimen náuseoso'.

La falta de higiene en ese restaurante era simplemente repugnante, algo más que solo un poco náuseoso.

In a medical context, you might also hear the term emético. This is a very technical word for something that causes vomiting. While you wouldn't use this in daily life, you might see it on medical packaging. On the other hand, if you just want to say you have an upset stomach, you can use the phrase 'tener el estómago revuelto' (to have a scrambled/upset stomach). This is a very common, idiomatic way to describe the early stages of feeling náuseoso.

Comparison Table
  • Náuseoso: The feeling of wanting to vomit (clinical/general).
  • Nauseabundo: Something that smells or looks so bad it causes nausea.
  • Asqueroso: Disgusting/gross (informal/very common).
  • Mareado: Dizzy/lightheaded.
  • Repugnante: Morally or physically revolting (strong).

Me siento un poco mareado por el calor, pero no estoy náuseoso, así que creo que estaré bien con un poco de agua.

Fue un espectáculo repulsivo que dejó a todo el público con un sentimiento náuseoso.

Choosing the right word from this list will make your Spanish sound more sophisticated and precise. Whether you are describing a bad smell, a spinning head, or a deep moral disgust, having these alternatives at your fingertips allows you to paint a much clearer picture of your internal state and external observations.

How to Use It

frequency

Common in medical, travel, and descriptive contexts.

Common Mistakes
  • Soy náuseoso. Estoy náuseoso.

    Using 'ser' means you are inherently sickening. 'Estar' is for the temporary feeling of sickness.

  • Estoy mareado del estómago. Estoy náuseoso.

    'Mareado' is for the head; 'náuseoso' is for the stomach. Don't mix the two locations.

  • nauseoso (without accent) náuseoso

    All esdrújula words (stressed on the third-to-last syllable) must have an accent.

  • Me siento náuseoso con esa película aburrida. Me aburre esa película.

    'Náuseoso' is for disgust, not boredom. In English, 'sick' can mean bored, but not in Spanish.

  • un olor náuseosa un olor náuseoso

    'Olor' is masculine, so the adjective must also be masculine.

Tips

Gender Agreement

Always remember to match 'náuseoso' with the subject. 'Él está náuseoso' vs 'Ella está náuseosa'. This is a basic but vital rule for B1 learners.

Travel Contexts

If you are prone to motion sickness, learn to say 'Me pongo náuseoso en el barco'. It will help people understand why you look pale!

Smell Descriptions

Use 'náuseoso' to describe smells that are physically overwhelming. It's more descriptive than just saying 'huele mal'.

Talking to Doctors

Use 'náuseoso' specifically to describe stomach issues. It helps medical professionals distinguish your symptoms from mere dizziness.

Moral Revulsion

Don't be afraid to use 'náuseoso' for moral situations. 'Su mentira fue náuseosa' is a powerful way to show your disgust.

The Accent Mark

Never forget the accent on the 'á'. It's a hallmark of correct Spanish writing for esdrújula words.

Vs. Mareado

Think: 'Mareado' is the head spinning; 'Náuseoso' is the stomach churning. Keeping them separate is key to clarity.

Stress the Náu

Put the emphasis on the very first part of the word: NÁU-se-o-so. This makes the word flow correctly.

Use Nauseabundo

For something that is truly, deeply disgusting to the point of being foul, 'nauseabundo' is your high-level alternative.

Cognate Power

Use your knowledge of the English word 'nauseous' to remember 'náuseoso', but be careful with the Spanish grammar rules!

Memorize It

Mnemonic

Think of a 'Nauseous' 'Oso' (bear in Spanish). Imagine a bear on a boat feeling sick. Nauseous + Oso = Náuseoso.

Visual Association

Picture a green-faced emoji on a rocking ship. The green color represents the 'náuseoso' feeling, and the ship reminds you of the word's origin.

Word Web

náusea estómago mareo vómito asco enfermo asqueroso malestar

Challenge

Try to use 'náuseoso' three times today: once for a physical feeling, once for a smell, and once for a situation you find morally disgusting.

Word Origin

Derived from the Latin 'nauseosus', which comes from 'nausea'. This, in turn, is derived from the Greek 'nausia', meaning ship-sickness or sea-sickness.

Original meaning: Originally specifically referred to the sickness caused by the motion of a ship ('naus' is Greek for ship).

Indo-European > Italic > Romance > Spanish.

Cultural Context

Be careful when using this word to describe people directly ('eres náuseoso'), as it is a very strong insult implying they are inherently disgusting.

English speakers often use 'nauseous' to mean 'nauseated'. In Spanish, 'náuseoso' works for both, but the distinction between 'estar' and 'ser' is the most important thing for English learners to master.

Jean-Paul Sartre's novel 'La Náusea' (The Nausea). Medical descriptions in the works of Gabriel García Márquez. Common tropes in Spanish 'telenovelas' where a character feels náuseosa to hint at pregnancy.

Frequently Asked Questions

10 questions

Both are correct and very common. 'Estoy náuseoso' uses an adjective to describe your state, while 'tengo náuseas' uses a noun to describe what you are experiencing. In casual conversation, 'tengo náuseas' is slightly more frequent, but 'estoy náuseoso' is perfectly natural and widely used.

Generally, no. Using 'ser' implies that being sickening is an inherent, permanent part of your personality. Unless you are insulting yourself or someone else, you should always use 'estar náuseoso' to describe a temporary feeling of sickness.

'Náuseoso' refers specifically to the stomach feeling like you might vomit. 'Mareado' refers to dizziness or feeling like the room is spinning. You can be both at the same time, especially when traveling, but they are different physical sensations.

Yes, but you must change the ending. A man says 'estoy náuseoso' and a woman says 'estoy náuseosa'. This is a standard rule for Spanish adjectives ending in '-o'.

It has an accent because it is an 'esdrújula' word. In Spanish, words where the stress falls on the third-to-last syllable always require a written accent. In this case, the stress is on the 'náu'.

It is a neutral to slightly formal word. In very informal settings, people might just say 'me da asco' or 'estoy mal del estómago'. However, 'náuseoso' is the standard term used in medical and professional contexts.

Yes, 'un olor náuseoso' is a common phrase. It means the smell is so bad it makes you feel like vomiting. For very strong, foul smells, 'nauseabundo' is also a great choice.

There isn't a single direct opposite, but words like 'sano' (healthy), 'bien' (well), or 'apetitoso' (appetizing, for food) are used depending on the context.

Yes, the word is universally understood across the Spanish-speaking world. While some regions might have local slang for feeling sick, 'náuseoso' remains the standard adjective everywhere.

The best translation for 'nauseated' is 'náuseoso' or the phrase 'con náuseas'. For 'nauseating', you can also use 'náuseoso' or 'nauseabundo'.
