1. Meaning and Usage
谁 (shuí) is an interrogative pronoun in Chinese, primarily meaning "who" or "whom." It is used to ask questions about people and can function as the subject, object, or possessive in a sentence.
2. Formulas and Examples
1. 谁 as the Subject of a Sentence
When asking "who" performed an action or "who" is someone/something, 谁 takes the place of the subject in the sentence.
Formula: $$谁 + Verb Phrase (+ Object)?$$
谁是你的老师? Shuí shì nǐ de lǎoshī? Who is your teacher?
谁吃了我的苹果? Shuí chī le wǒ de píngguǒ? Who ate my apple?
2. 谁 as the Object of a Sentence
When asking "whom" an action is directed towards, 谁 takes the place of the object in the sentence.
Formula: $$Subject + Verb + 谁?$$
你认识谁? Nǐ rènshi shuí? Whom do you know?
他想见谁? Tā xiǎng jiàn shuí? Whom does he want to see?
3. 谁的 (shuí de) for Possessive
To ask "whose" something is, 谁 is followed by 的 (de).
Formula: $$这是/那是 + 谁的 + Noun?$$
这是谁的书? Zhè shì shuí de shū? Whose book is this?
那是谁的手机? Nà shì shuí de shǒujī? Whose phone is that?
4. 谁 with 是...的 (shì...de) Structure for Emphasis
The 是...的 (shì...de) structure is used to emphasize the time, place, manner, or agent of a past action. When asking "who was it that did X," 谁 is placed after 是.
Formula: $$是谁 + Verb + (Object) + 的?$$
是谁给你打了电话? Shì shuí gěi nǐ dǎ le diànhuà? Who was it that called you?
是谁发明了灯泡? Shì shuí fāmíng le dēngpào? Who was it that invented the light bulb?
5. 谁 in Non-Interrogative Contexts (Referring to "Everyone" or "No one")
In some advanced usages, 谁 can be used with adverbs like 都 (dōu) or 也 (yě) to mean "everyone" or "no one," respectively.
a. 谁都... (shuí dōu...) - Everyone/Anyone
Used to indicate "everyone" or "anyone" without a specific person in mind.
Formula: $$谁都 + Verb/Adjective + (Object)$$
谁都喜欢他。 Shuí dōu xǐhuān tā. Everyone likes him.
这件事谁都知道。 Zhè jiàn shì shuí dōu zhīdào. Everyone knows about this matter.
b. 谁也... (shuí yě...) - No one/Nobody
Used with a negative (不/没) to indicate "no one" or "nobody."
Formula: $$谁也 + 不/没 + Verb/Adjective + (Object)$$
谁也不知道。 Shuí yě bù zhīdào. Nobody knows.
谁也没看见他。 Shuí yě méi kànjiàn tā. Nobody saw him.
3. Essential HSK Tips & Common Mistakes
Tip 1: Position is Key. The interrogative pronoun 谁 directly replaces the person you are asking about, whether they are the subject, object, or part of a possessive phrase. The sentence structure remains largely the same as a declarative sentence.
- Correct usage (subject replacement):
他去了。 -> 谁去了? Tā qù le. -> Shuí qù le? He went. -> Who went?
- Correct usage (object replacement):
我看见了她。 -> 你看见了谁? Wǒ kànjiàn le tā. -> Nǐ kànjiàn le shuí? I saw her. -> Whom did you see?
- Correct usage (subject replacement):
Tip 2: No need for 吗 (ma). When 谁 is used, the sentence is already a question, so you generally do not add the question particle 吗 (ma) at the end.
- Incorrect:
他是谁吗? Tā shì shuí ma? (Incorrect way to ask "Who is he?")
- Correct:
他是谁? Tā shì shuí? Who is he?
- Incorrect:
Tip 3: Distinguish 谁 (shuí) from 什么 (shénme). Remember that 谁 is exclusively for asking about people, while 什么 (shénme) is for asking about things or what.
- Correct (asking about a person):
你喜欢谁? Nǐ xǐhuān shuí? Whom do you like?
- Correct (asking about a thing/what):
你喜欢什么? Nǐ xǐhuān shénme? What do you like?
- Common Mistake: Using 什么 when asking about a person. For example,
你是谁?(Who are you?) is correct, not你是什么?(What are you? - which would be offensive if directed at a person).
- Correct (asking about a person):
