Welcome back. In our last lesson, you learned how to ask for confirmation using the yes/no question particle 吗 (ma). We established that you simply add 吗 to the end of a statement, and that you must not use it with other question words.
Today, we will learn how to use those other question words. While 吗 helps you ask "is it or isn't it?", the words we'll cover today allow you to ask for specific information: who, what, and where. This lesson is pivotal because it introduces a fundamental, and remarkably efficient, principle of Chinese grammar. By the end of this session, you will be able to use 什么 (shénme - what), 谁 (shéi - who), and 哪儿 (nǎr - where) to ask for specific details, dramatically expanding your conversational ability.
The In-Situ Principle: A Logical Approach to Questions
In English, to ask a question like "What is this?", we move the question word "what" to the front and invert the subject and verb ("this is" becomes "is this"). Chinese grammar follows a much more direct rule, which can be thought of as a simple substitution operation.
The core principle is that the question word goes in the exact spot where the answer would be in a declarative sentence. The rest of the sentence structure remains unchanged. This is often called the "in-situ" (in place) position for question words.
Consider this logic:
- Statement:
This is [a book]. - Question:
This is [what]?
In Chinese, this is exactly how it works:
- Statement: 这是书。(Zhè shì shū.)
- Question: 这是什么?(Zhè shì shénme?)
This elegant rule applies to all content question words. The article from HSKLord provides an excellent overview of this concept.
Question Word Questions (什么, 谁, 哪) (疑问代词) — Chinese Grammar | HSKLord
This resource concisely explains the core rule for forming content questions in Chinese. It highlights the simplicity compared to English and sets the foundation for everything we'll cover today.
Read the "TL;DR" and the "Explanation" section. Pay close attention to the example it uses: "Consider the statement '他是老师'". This example clearly demonstrates how 谁 (who) and 什么 (what) slot into the sentence without disturbing the word order. Also, note the important reminder about not using 吗.
Now, let's examine our three target question words.
1. 什么 (shénme) - What
什么 (shénme) is used to ask about objects, information, or abstract concepts. It almost always occupies the object position in a sentence.
- Structure: Subject + Verb + 什么?
- Example:
- Question: 这是什么? (Zhè shì shénme?)
- Meaning: What is this?
- Possible Answer: 这是书。 (Zhè shì shū.) - This is a book.
Notice how the answer, 书 (shū), is in the same "slot" as the question word 什么 (shénme).
2. 谁 (shéi) - Who
谁 (shéi) is used to ask about people. It can occupy either the subject or the object position. The pronunciation shuí is also common and correct.
-
As an object:
- Question: 他是谁? (Tā shì shéi?)
- Meaning: Who is he?
- Possible Answer: 他是老师。(Tā shì lǎoshī.) - He is a teacher.
-
As a subject:
- Question: 谁是老师? (Shéi shì lǎoshī?)
- Meaning: Who is a teacher?
- Possible Answer: 他是老师。(Tā shì lǎoshī.) - He is a teacher.
3. 哪儿 (nǎr) - Where
哪儿 (nǎr) is used to ask about places and locations. It follows the same in-situ principle, replacing the location phrase in a statement.
- Structure: Subject + Verb (often 在, zài) + 哪儿?
- Example:
- Question: 你在哪儿?(Nǐ zài nǎr?)
- Meaning: Where are you?
- Possible Answer: 我在家。(Wǒ zài jiā.) - I am at home.
A common variant you will encounter is 哪里 (nǎlǐ). As the Chinese Grammar Wiki explains, nǎr is more common in northern China (like Beijing), while nǎlǐ is more common in the south. They are completely interchangeable. For the HSK, you should be able to recognize both, but using nǎr is perfectly fine.
The Chinese Grammar Wiki resource provides clear, separate sections for each of these question words, which can help solidify your understanding.
Placement of question words - Chinese Grammar Wiki
This article from the Chinese Grammar Wiki reinforces the in-situ rule and gives separate, focused examples for each question word.
Focus on the sections titled "Expressing 'What' with 什么 (shénme)", "Expressing 'Where' with 哪里 (nǎlǐ) / 哪儿 (nǎr)", and "Expressing 'Who' with 谁 (shéi)". Read the structure and one or two examples from each to see the pattern in action.
To hear these words and their usage, the following video provides clear examples and pronunciation.
How to Ask Questions in Chinese - All Basic Chinese Question Words You Should Know
This video from the Everyday Chinese channel walks through several common question words. Focus on the sections for our three target words to connect the characters and Pinyin with the correct sounds.
Please watch the segments covering: 'What' with 什么 (shénme), which starts around this point. 'Who' with 谁 (shéi), found around this mark. 'Where' with 哪儿 (nǎr), beginning around here.
Synthesis and Visual Review
You have now seen the core logic and individual usage of 什么, 谁, and 哪儿. The infographic below is a useful reference that gathers several common question words in one place. For today's lesson, focus on the bubbles for What (什么), Who (谁), and Where (哪里/哪儿).

Remember the most important rule we've discussed, which was previewed in the last lesson and emphasized in today's resources:
A sentence can have a question word OR it can have 吗, but never both.
你叫什么名字?(Nǐ jiào shénme míngzì?) - What is your name? (Correct)你是老师吗?(Nǐ shì lǎoshī ma?) - Are you a teacher? (Correct)你叫什么名字吗?- Incorrect. The presence of什么already makes it a question.
Conclusion
You've made a significant leap today. By mastering the in-situ principle, you've grasped one of the most fundamental and logical aspects of Chinese grammar. You are no longer limited to asking for yes/no confirmation; you can now actively request new information.
Key Takeaways:
- The In-Situ Principle: Chinese question words preserve the basic SVO sentence structure. They simply replace the "unknown" piece of information.
- Core Question Words:
- 什么 (shénme) asks "what" and typically replaces the object.
- 谁 (shéi) asks "who" and can replace either the subject or the object.
- 哪儿 (nǎr) asks "where" and replaces the location phrase.
- The Golden Rule: Never use
吗in a sentence that already contains a question word like什么,谁, or哪儿.
In our next lesson, we will begin learning how to introduce yourself and others. You'll immediately get to put today's grammar into practice by learning how to ask "What is your name?" (你叫什么名字?) and "Who is this?" (这是谁?).
