Explicação 排尿 in your Level:

At the A1 level, you don't really need to use the word '排尿' (pái niào) because it is very formal and medical. Instead, beginners usually learn '上厕所' (shàng cè suǒ), which means 'to go to the toilet.' If you are at this level, just know that '尿' (niào) means 'urine' or 'pee.' You might see the character '尿' on signs or in very basic health contexts. For an A1 learner, the focus should be on survival phrases like '厕所在哪儿？' (Where is the toilet?). However, it is good to recognize the character '尿' because it appears in many words related to health. Think of '排尿' as a 'doctor word' that you will learn later. If you see it now, just remember it means the action of using the bathroom for liquid waste. It's like learning the word 'urinate' before you've even learned 'bathroom'—it's possible, but not the most urgent thing to know! Just focus on the fact that '排' means to push out and '尿' is the waste. This will help you later when you see other words like '排队' (pái duì - to stand in a line/push into a line). Even at A1, knowing that '尿' has the 'body' radical (尸) and 'water' (水) can be a fun way to remember how characters are built. It's a very logical character! But for now, stick to simple phrases for your daily needs.

By A2, you are starting to expand your vocabulary beyond just the most basic needs. You might encounter '排尿' (pái niào) if you are reading a simple health brochure or a sign in a hospital. At this level, you should understand that '排尿' is the formal version of '小便' (xiǎo biàn). While you might still use '我要去小便' (I need to urinate/pee) in a polite way, '排尿' is what the doctor will say to you. You should be able to recognize it in writing. For example, if a medicine bottle says '可能引起排尿增加' (may cause increased urination), you should be able to figure out that it's talking about a side effect. You don't necessarily need to produce this word in conversation yet, but you should be able to understand it when you hear it in a professional context. It's also a good time to learn the difference between '排' (to discharge) and other similar-looking characters. A2 learners should focus on the 'verb + noun' structure of this word. It's a compound word where the first part is the action and the second part is the thing being acted upon. This is a very common pattern in Chinese, and '排尿' is a perfect example of it. You might also start to see it in compound words like '排尿系统' (urinary system) in very basic science contexts. Just remember: '排尿' = formal/medical, '小便' = polite/daily, '尿尿' = kids.

At the B1 level, you are expected to handle more formal situations, such as a visit to a clinic or discussing health topics in more detail. This is the level where '排尿' (pái niào) becomes a truly useful part of your active vocabulary. You should be able to use it to describe symptoms or understand medical advice. For instance, if you have a bladder infection, you would use '排尿' to describe the pain or frequency to a healthcare provider. You are also moving into more abstract reading materials where this word might appear in a discussion about biology or environmental hygiene. At B1, you should also be aware of the register. You know that using '排尿' with your friends is a bit too much, but using it in a written report or a formal speech is perfect. You should also be familiar with common collocations like '排尿困难' (difficulty urinating) or '频繁排尿' (frequent urination). This is also the stage where you might start noticing the word in news reports about health trends or scientific discoveries. You should be comfortable seeing it in a sentence and understanding its grammatical role as a verb-object compound. It's a key word for achieving 'functional' fluency in health-related topics, which is a major component of the B1 level. You should also start to notice how '排' is used in other 'discharge' words like '排放' (pái fàng - to emit/discharge pollution), which helps you build a deeper understanding of the Chinese language's logic.

At the B2 level, you should have a nuanced understanding of '排尿' (pái niào) and be able to use it fluently in professional or academic contexts. You should understand the physiological implications of the word and be able to discuss topics like '排尿机制' (the mechanism of urination) or '排尿障碍' (urinary disorders). At this level, you aren't just translating the word; you are understanding it within the framework of Chinese medical and scientific terminology. You should be able to read medical reports or detailed health articles that use '排尿' alongside other advanced terms like '肾功能' (kidney function) or '代谢' (metabolism). You should also be able to distinguish '排尿' from more specific terms like '遗尿' (bed-wetting/enuresis) or '利尿' (diuresis). In a B2 level discussion, you might use '排尿' to talk about the side effects of a specific medication or the biological adaptations of animals in desert environments. You should also be aware of the word's use in formal legal or regulatory documents, such as those regarding sports doping tests (尿检 - niào jiǎn). Your ability to switch between '排尿', '小便', and '撒尿' depending on the audience and setting should be seamless. This level requires you to not only know the word but to understand its place in the broader 'ecology' of the Chinese language. You might even encounter it in literature where a writer chooses a clinical tone to create a specific atmosphere of detachment or realism.

As a C1 learner, your mastery of '排尿' (pái niào) extends to its use in highly specialized fields and complex literary structures. You should be able to comprehend academic papers in medicine, biology, or pharmacology where '排尿' is used to describe intricate physiological processes. You will understand the nuances of how '排尿' interacts with other bodily functions in a systemic view of health. At this level, you might encounter the word in historical texts or classical-style modern writing where the choice of '排尿' over more common terms serves a stylistic purpose. You should also be familiar with the word's presence in idioms or professional jargon that might not be immediately obvious to lower-level learners. For instance, in the context of traditional Chinese medicine (TCM), '排尿' is linked to the 'Bladder Meridian' (膀胱经), and you should be able to discuss its role in that theoretical framework. You should also be able to handle complex grammatical structures where '排尿' is part of a long, nested sentence describing a medical procedure or a biological study. Your understanding of the word is now integrated with a deep knowledge of Chinese culture, science, and formal communication. You can explain the difference between '排尿' and other forms of '排泄' with scientific precision. You are also likely to encounter this word in news reports about public health policy or environmental regulations regarding animal waste management, and you should be able to synthesize that information effectively.

At the C2 level, '排尿' (pái niào) is a word you understand with the depth of a native speaker or a professional in a related field. You can navigate the most complex medical journals, legal statutes, and philosophical treatises where the word might appear. You understand the subtle connotations it carries in different historical periods or regional dialects of formal Chinese. You might even be able to discuss the evolution of the characters '排' and '尿' from their ancient forms to their modern usage. In professional settings, you can use '排尿' to deliver a lecture, write a technical manual, or participate in a high-level medical consultation without hesitation. You are also aware of how this word is used in specialized slang or metaphors within the medical community. Your command of the register is perfect; you know exactly when '排尿' is the only appropriate term and when it would be a stylistic error. At C2, you are also sensitive to the word's use in sensitive or taboo topics, and you can navigate those conversations with the appropriate level of decorum and precision. Whether it's a discussion on the ethics of mandatory drug testing or a deep dive into the biochemistry of renal failure, '排尿' is a tool you use with total confidence and accuracy. You see the word not just as a vocabulary item, but as a small piece of the vast, interconnected web of the Chinese language and its reflection of human biology and society.

排尿 em 30 segundos

排尿 (pái niào) is the formal Chinese verb for 'to urinate,' used primarily in medical, scientific, and professional health contexts rather than casual conversation.
It consists of '排' (discharge) and '尿' (urine), making it a verb-object compound that functions as the technical standard for biological excretion.
Commonly found in hospital settings, medical reports, and biology textbooks, it is more formal than '小便' and much more formal than '尿尿'.
Learners should use this word when talking to doctors or writing formal reports, but avoid it in casual social settings to sound more natural.

The term 排尿 (pái niào) is a formal and clinical Chinese verb that translates to 'to urinate' or 'to void urine.' While the English word 'urinate' can feel slightly sterile, its Chinese counterpart carries a specific weight of medical and biological accuracy. In daily life, Chinese speakers typically use more colloquial terms like 尿尿 (niào niào) or 上厕所 (shàng cè suǒ), but 排尿 is the absolute standard in hospitals, scientific papers, health brochures, and formal fitness discussions. Understanding this word is crucial for anyone navigating the Chinese healthcare system or reading serious literature about biology and wellness. It consists of two characters: 排 (pái), meaning to discharge, push out, or eliminate, and 尿 (niào), which means urine. Together, they describe the physiological process of the body releasing liquid waste through the bladder and urethra.

Register: Formal, Medical, Biological, and Academic.
Etymology: 排 (discharge) + 尿 (urine). The character 尿 visually depicts water (水) under a body (尸).

医生询问病人是否有排尿困难的情况。(The doctor asked the patient if they had any difficulty urinating.)

Furthermore, the word is often found in health metrics. For example, when discussing kidney function, '排尿量' (urine output) is the standard metric. In traditional Chinese medicine (TCM), the quality and frequency of one's 排尿 are considered vital indicators of the body's 'Qi' and 'Yang' balance. For instance, frequent urination at night is called '尿频' (niào pín), but the act itself is still referred to as 排尿 in the diagnosis. This word bridges the gap between basic biological functions and professional health management.

正常的排尿有助于排除体内的毒素。(Normal urination helps eliminate toxins from the body.)

Contextual Usage: Used in clinical records, pet health instructions, and formal scientific education materials.

Culturally, the Chinese language is very sensitive to social register. Using 排尿 in a casual conversation might be seen as overly clinical or even slightly humorous due to its stiffness. However, if you are at a pharmacy or talking to a nurse, using this term shows a high level of linguistic competence and respect for the professional setting. It is essentially the difference between saying 'I gotta pee' and 'I am experiencing a need to urinate.' By mastering this word, you prepare yourself for more complex interactions where precision matters more than social ease. The word also appears in environmental contexts, such as the '排尿' of certain aquatic animals in biological studies.

这种药物可能会增加排尿的频率。(This medication may increase the frequency of urination.)

Morphology: 排 (Verb) + 尿 (Noun acting as object) = To discharge urine. This is a verb-object compound.

Using 排尿 correctly requires an understanding of its grammatical role. It usually functions as a verb, but it can also act as a noun (the act of urinating). For example, in the phrase '排尿过程' (the process of urination), it serves as a modifier for the noun. When used as a verb, it rarely takes a direct object because '尿' (urine) is already built into the word structure as the object of '排' (to discharge). Therefore, you wouldn't say '排尿尿' because that would be redundant. Instead, you use it as a complete action or modify it with adverbs that describe frequency, difficulty, or volume.

术后患者需要观察第一次排尿的时间。(After surgery, the patient's first urination time needs to be observed.)

In medical instructions, you will often see it paired with '困难' (kùn nán - difficulty) or '痛' (tòng - pain). For example, '排尿困难' (difficulty urinating) is a very common phrase in medical intake forms. Another common structure is '促进排尿' (to promote/encourage urination), often used when discussing the effects of diuretics or drinking plenty of water. Because it is a formal word, it often appears in 'if...then' structures or instructions provided by healthcare professionals. It is also frequently found in the context of diagnostic tests, such as '排尿后余尿' (residual urine after voiding).

如果感到排尿疼痛，请立即就医。(If you feel pain during urination, please seek medical attention immediately.)

Common Pattern 1: [Condition] + 影响 (affects) + 排尿. Example: 这种疾病会影响正常排尿。
Common Pattern 2: [Time/Frequency] + 排尿. Example: 每日排尿次数增加。

Another interesting usage is in the context of animal behavior and ecology. Scientists studying the habits of wild animals will use '排尿' to describe how animals mark their territory. In this context, it is not just a biological necessity but a communicative act. For instance, '雄性狮子通过排尿来标记领地' (Male lions mark their territory through urination). This demonstrates that while the word is formal, it is the standard 'technical' term for the action regardless of the subject (human or animal). In writing, it is often used to maintain a neutral, objective tone, avoiding the emotional or vulgar connotations of slang.

有些动物在惊吓时会出现非自主性排尿。(Some animals experience involuntary urination when startled.)

Formal Usage: In legal or official reports (e.g., drug testing results), the term '排尿' is used to describe the collection of samples.

You are most likely to encounter 排尿 in a hospital or clinic setting. If you visit a doctor in China for any urinary tract issue, this is the word they will use. You will hear it in phrases like '排尿时有灼热感吗？' (Do you have a burning sensation when urinating?). It is the 'safe' word for medical professionals because it is precise and lacks the potentially offensive or childish tone of colloquialisms. Beyond the hospital, you will hear it in health-related podcasts, television segments about elderly care, and in public service announcements about hygiene and kidney health. For example, a commercial for a health supplement targeting prostate health will use '排尿' repeatedly to maintain a professional, trustworthy image.

在体检中心，护士会告诉你要保留排尿以便化验。(At the physical exam center, the nurse will tell you to hold your urine for the test.)

In the digital age, '排尿' also appears in fitness apps and health tracking software. If you use a smart water bottle or a health monitoring app that tracks hydration levels, the notification might say '请记录您的排尿情况' (Please record your urination status). It is also used in parenting blogs when discussing toilet training from a developmental or psychological perspective, though parents will switch to '尿尿' when talking directly to their toddlers. In academic lectures—whether they are about biology, nursing, or even urban planning (sewage systems)—this is the standard term used to describe the biological output of a population.

专家建议，每天应该保持足够的排尿量以防止肾结石。(Experts suggest maintaining sufficient urine output daily to prevent kidney stones.)

Finally, you will find this word in the context of sports and doping tests. When athletes are required to provide a sample, the official terminology is always '排尿' or '尿样采集' (urine sample collection). In these high-stakes, professional environments, slang is strictly avoided to ensure there is no ambiguity in legal or procedural documentation. Even in news reports about such events, journalists will use '排尿' to describe the process. This highlights the word's role as the definitive, objective term for the act in any context that requires a level of seriousness or scientific validity. If you are watching a medical drama on Chinese television, listen closely during the surgery or diagnosis scenes; you will hear it frequently.

运动员在比赛后必须在监督下进行排尿取样。(Athletes must undergo supervised urination for sampling after the race.)

Media Usage: News reports, medical journals, health documentaries, and fitness app interfaces.

One of the most common mistakes learners make with 排尿 is using it in the wrong social context. Because it is a B1/B2 level word, students often feel proud to use it, but using it with friends can make you sound like a robot or a doctor. Imagine being at a party and saying, 'I must go and urinate now.' It’s grammatically correct but socially awkward. In casual settings, use '去洗手间' (qù xǐ shǒu jiān) or '去厕所' (qù cè suǒ). Another mistake is confusing it with '排泄' (pái xiè). While '排尿' specifically refers to urination, '排泄' is a broader term for excretion, which includes both urination and defecation. Using '排泄' when you specifically mean 'urinate' might be too vague in a medical context.

错误：我要去排尿了。(Wrong context: I am going to urinate now - too formal for friends.)

A grammatical mistake involves the structure of the word itself. As mentioned before, '排尿' is a verb-object (VO) compound. This means you cannot typically put another object after it. You cannot say '排尿水' (pái niào shuǐ). If you want to describe what is being excreted, the word '尿' is already there. Similarly, some learners try to use it as a simple noun without a measure word or context. In '他的排尿很不正常' (His urination is very abnormal), it works as a noun phrase, but you wouldn't just say '我有排尿' (I have urination). You would say '我有排尿困难' (I have difficulty urinating) or '我刚排过尿' (I just urinated).

正确：他在排尿时感到不适。(Correct: He felt discomfort while urinating.)

Learners also sometimes struggle with the pronunciation of the second character '尿'. It is 'niào' (fourth tone), but some might accidentally say 'niǎo' (third tone), which means 'bird'. While context usually helps, saying 'discharge bird' instead of 'discharge urine' is a classic and embarrassing mistake for beginners. Furthermore, ensure you don't use '排尿' to describe the act of a baby unless you are talking to a pediatrician. For babies, the term is almost always '尿尿' (niào niào) or '嘘嘘' (shū shū). Using the technical term for a baby's diaper change sounds strangely scientific and cold in a family setting. Finally, remember that '排' is the 2nd tone (pái), not the 3rd tone (pǎi).

医生，我最近排尿次数很多。(Doctor, I have been urinating many times lately.)

Distinction: 排尿 (Urinate - formal) vs. 撒尿 (Pee - very informal/crude) vs. 尿尿 (Pee - childish/cute).

There are several ways to express the act of urinating in Chinese, depending on how formal you want to be. 排尿 is at the top of the formality scale. Below it, we have 小便 (xiǎo biàn). '小便' is the most common polite term used in semi-formal situations, such as when a teacher asks a student or when reading signs in public restrooms. It literally means 'small excrement' (contrasted with '大便' for defecation). While '排尿' is medical, '小便' is the standard polite word for daily life. If you are talking to a doctor, both are acceptable, but '排尿' is more clinical.

Comparison: 排尿 vs 小便: 排尿 is the biological process (voiding); 小便 is the social act (peeing/urination). You would see '排尿困难' in a textbook but might say '小便不通' in a general discussion.

Another alternative is 尿尿 (niào niào). This is the 'child-speak' version, similar to 'pee-pee' in English. It is used by parents with children or sometimes between close couples to sound cute (though this is rare). On the other end of the spectrum is 撒尿 (sā niào). This is very informal and can sometimes be seen as crude or vulgar, similar to 'taking a leak.' It is often used when talking about animals (like a dog peeing on a tree) or in very rough, informal speech among men. Using '撒尿' in a professional or polite environment would be considered quite rude.

除了排尿，医生还检查了他的排便情况。(In addition to urination, the doctor also checked his bowel movements.)

In technical or ecological contexts, you might see 排泄 (pái xiè). As mentioned, this is the umbrella term for all biological waste removal. If you are reading a biology textbook about how cells remove waste, you will see '排泄' rather than '排尿'. Another related term is 利尿 (lì niào), which means 'diuretic' or 'promoting urination.' You will see this on the labels of certain teas (like dandelion tea) or medications. Understanding these nuances helps you choose the right word for the right situation, ensuring you sound educated but not robotic, and polite but not overly clinical.

Register Ladder: 1. 排尿 (Medical/Formal)
2. 小便 (Polite/Standard)
3. 尿尿 (Childish/Casual)
4. 撒尿 (Crude/Informal)

How Formal Is It?

Curiosidade

In ancient scripts, '尿' was sometimes written with the 'water' radical on the side, but the 'body + water' structure became the standard because it was so visually intuitive. It is one of the few characters where the meaning is still obvious even to non-speakers once explained.

Guia de pronúncia

UK /paɪ njaʊ/

US /paɪ njaʊ/

The emphasis is equal on both syllables, but the falling tone of 'niào' naturally makes it sound slightly more emphatic in a sentence.

Rima com

台 (tái) 来 (lái) 海 (hǎi - approximate) 笑 (xiào) 叫 (jiào) 跳 (tiào) 妙 (miào) 药 (yào - approximate)

Erros comuns

Pronouncing 'pái' as 'bái' (forgetting aspiration).
Pronouncing 'niào' as 'niǎo' (using the 3rd tone instead of the 4th, meaning 'bird').
Pronouncing 'pái' with a flat tone (1st tone) instead of rising (2nd tone).
Splitting 'niào' into 'ni-ao' instead of a smooth diphthong.
Using the English 'u' sound for 'niào' instead of the Chinese 'iao' sound.

Dicas

Medical Settings

Always use '排尿' when speaking with doctors or filling out medical forms in China. It shows you are serious about your health and use the correct terminology.

Verb-Object Structure

Treat '排尿' as a single unit. Because it's a VO compound, you don't need to add another object after it. If you want to add a description, put it between '排' and '尿' or after the whole word.

Social Appropriateness

If you are at a dinner party, never say '我去排尿' (I'm going to urinate). Instead, say '我去方便一下' (I'm going to relieve myself) to be polite.

The Fourth Tone

Make sure 'niào' is a sharp, falling tone. If you say it with a rising tone, it sounds like 'bird' (鸟), which can lead to confusing and funny situations.

Related Systems

Learn '排尿' alongside '排便' (to defecate). Together they cover the formal terms for bodily waste removal.

Character Balance

When writing '尿', make sure the '水' is centered under the '尸' to keep the character balanced and legible.

TV Dramas

Watch Chinese medical dramas to hear how doctors use '排尿' in different contexts. It will help you internalize the professional register.

Scientific Context

Remember that '排尿' is used for all mammals in scientific Chinese, not just humans. It is the objective term for the biological process.

Restroom Signs

Restroom signs in China usually say '洗手间' or '厕所', but instructions inside might use '排尿' to describe how to use specific medical or technical facilities.

The 'Pai' Family

Group '排尿' with '排队' (queue) and '排放' (emit). The common thread is 'pushing out' or 'arranging in a line'.

Memorize

Mnemônico

Think of 'Pai' (排) like 'Pie' - if you eat too much pie and drink water, you need to 'Pai' (discharge). 'Niào' (尿) looks like a person (尸) standing over water (水).

Associação visual

Imagine a hospital sign with a diagram of a bladder and an arrow pushing (排) liquid (尿) out. The character 尿 itself is a perfect visual of a body over water.

Word Web

排泄 (excretion) 尿液 (urine) 膀胱 (bladder) 医生 (doctor) 医院 (hospital) 喝水 (drink water) 健康 (health) 洗手间 (restroom)

Desafio

Try to use '排尿' in three different sentences describing a visit to a doctor. Then, try to explain the difference between '排尿' and '小便' to a friend.

Origem da palavra

The character '排' (pái) consists of the 'hand' radical (扌) and '非' (fēi). Originally, it meant to push or arrange things with the hands. The character '尿' (niào) is a classic ideogram: the top part '尸' represents a human body or person, and the bottom part '水' represents water. Together, 'water from the body' clearly indicates urine.

Significado original: To discharge liquid waste from the human body.

Sino-Tibetan

Contexto cultural

This word is safe and professional. It is not offensive, but it is too clinical for casual conversation. Avoid using it with friends unless discussing a serious health issue.

In English, we have a similar scale: Pee (informal/childish) -> Go to the bathroom (polite) -> Urinate (formal/medical). '排尿' is exactly like 'Urinate'.
