pee

Compared meaning: to release urine from the body (verb).

比较义项：撒尿（动词）。

• piss

  Piss is a vulgar, taboo way to say this — rude in polite company, common in crude or angry speech, and part of idioms like "pissed off"; avoid it in formal or polite contexts.

  piss是粗俗、忌讳的说法，在礼貌场合显得无礼，常见于粗鲁或愤怒的表达中，也用于pissed off等习语；应避免在正式或礼貌场合使用。

  He stumbled out of the pub and pissed against the wall.

  他从酒吧摇摇晃晃地走出来，对着墙撒尿。

• pee 本词

  Pee is a mild, everyday informal word — polite enough for children, family or casual conversation, without the crudeness of piss or the clinical stiffness of urinate.

  pee是温和、日常的口语用词，礼貌程度足以用于儿童、家人或朋友间的随意交谈，既没有piss的粗俗，也没有urinate的生硬。

  Mom, I really need to pee before we get in the car.

  妈妈，我们上车之前我真的很想尿尿。

• urinate

  Urinate is the formal, clinical term used by doctors, nurses and in official writing; it sounds stiff and distant in casual conversation, where pee or piss would be used instead.

  urinate是医生、护士及正式文书中使用的正式、临床用词；在日常随意的对话中显得生硬疏远，那种场合通常会用pee或piss。

  The nurse asked the patient to urinate into a small plastic cup.

  护士让病人往一个小塑料杯里小便。

All three mean to urinate, but differ in register. Piss is vulgar and taboo; avoid it in polite settings. Pee is mild, fine even for children. Urinate is formal and clinical, used in medicine. Piss can also mean 'rain hard' or 'anger'; not compared here.

这三个词在“排尿”这一义项上意思相同，但语域差异很大：piss 是粗俗、忌讳的词，正式或礼貌场合应避免；pee 是中性偏口语的说法，可用于儿童或熟人之间；urinate 是正式、医学化的用词，多见于医疗或正式书面语。这里不比较 piss 表示“猛下大雨”（piss down）或“使…生气”（piss off）的用法。

Compared meaning: the liquid waste passed from the body (noun).

比较义项：尿，小便（名词）。

• urine

  The clinical, formal term used in medical, scientific or official contexts; common in phrases like 'urine sample' or 'urine test'.

  医学、科学或正式场合使用的临床用词，常出现在“尿样”“尿检”等说法中。

  The nurse labeled the urine sample before sending it to the lab.

  护士在把尿样送去化验之前先给它贴上了标签。

• pee 本词

  An informal, everyday word, often used with children or pets; sounds too casual for medical or official contexts.

  口语化的日常用词，常用于对儿童或宠物说话；在医学或正式场合使用会显得太随意。

  Can you take the dog outside? He needs to pee.

  你能带狗出去一下吗？它要尿尿了。

Both words name the liquid waste the body passes, but differ in register. Urine is the clinical, formal term, used in medical or official contexts, as in 'urine sample'. Pee is informal and everyday, often used with children, and sounds too casual for medical writing.

这两个词都指人体排出的液态废物，但语域不同：urine 是医学、正式场合的说法，pee 是日常口语甚至略显幼稚的说法，两者一般不能互换使用。
