Welcome back. In our last lesson, you learned how to form and negate basic identity statements using 是 (shì) and 不是 (bú shì). This gave you the power to state facts like "I am a student" or "He is not a teacher." Today, we will build directly on that foundation to ask questions.
The goal of this lesson is to master the simplest and most common way to form yes/no questions in Mandarin. By the end of our session, you will be able to take any statement you learned to make in the previous lesson and turn it into a question, such as "Are you a teacher?", using the final particle 吗 (ma).
From Statement to Question: The 吗 Particle
In English, forming a yes/no question often involves reordering words ("You are a teacher" -> "Are you a teacher?"). Mandarin grammar offers a more streamlined, computationally simple approach. To turn a declarative sentence (a statement) into a yes/no question, you simply append the particle 吗 (ma) to the end. The word order of the original statement remains completely unchanged.
The structure is: Statement + 吗?
The character 吗 (ma) is pronounced with a neutral tone. This means it is unstressed, short, and light, almost like it's latching onto the syllable before it. It functions as a spoken question mark, signaling that you are seeking a 'yes' or 'no' confirmation.
Let's apply this to the sentences we already know:
-
Statement: 你是老师。(Nǐ shì lǎoshī.) — You are a teacher.
-
Question: 你是老师吗？(Nǐ shì lǎoshī ma?) — Are you a teacher?
-
Statement: 他是学生。(Tā shì xuéshēng.) — He is a student.
-
Question: 他是学生吗？(Tā shì xuéshēng ma?) — Is he a student?
The Chinese Grammar Wiki provides an excellent, concise explanation of this fundamental rule.
Yes-no questions with "ma" - Chinese Grammar Wiki
This article clearly lays out the structure for forming yes-no questions. It reinforces the idea that 吗 is like a "question mark you say out loud."
Please read the sections under "Basic Usage." Focus on the core structure presented: Statement + 吗？. Then, look at the examples provided, particularly those using 是 (shì), such as this one and this one.
To hear this in practice, the following video explains the concept very clearly. The presenter's analogy of 吗 meaning "am I right?" can be a very helpful mental model.

This video from Chinese Zero to Hero walks through the process of creating a 吗 question.
Please watch from the main explanation. Listen for the pronunciation of 吗 at the end of the sentences—it's quick and unstressed. Then, watch the short practice where the presenter turns "You are a student" into "Are you a student?".
The infographic below neatly contrasts the two main types of simple questions. For today's lesson, we are focused entirely on the right side: Yes/No questions using 吗 (ma).
Answering 吗 Questions
This is a critical point where Chinese grammar diverges from English. In English, we have the all-purpose words "yes" and "no." In Mandarin, the way you answer depends on the main verb in the question.
To answer "yes," you repeat the verb from the question.
To answer "no," you negate the verb from the question.
Let's look at the questions we've been using, which are all based on the verb 是 (shì):
Question: 你是老师吗？ (Nǐ shì lǎoshī ma?) - "Are you a teacher?"
- Affirmative Answer ("Yes"): 是。(Shì.)
- Negative Answer ("No"): 不是。(Bú shì.)
This is why you learned 是/不是 in the last lesson. When you ask a question with 是, these are your "yes" and "no." If the question used a different verb, like 喜欢 (xǐhuān - to like), the answer would be 喜欢 ("yes") or 不喜欢 ("no"). This verb-centric answering system is a core concept in the language.
The Chinese Grammar Wiki again provides a very clear breakdown of this.

This next section of the same article explains the answering mechanism.
Please read the section titled "How to Answer". Pay close attention to the final paragraph, which begins "You sometimes hear...". This is the key takeaway: the verb of the question is the word for "yes".
A Critical Rule: Avoid Redundancy
Because 吗 turns a statement into a question, you must not use it in a sentence that already contains a question word. Words like 谁 (shéi - who), 什么 (shénme - what), or 哪儿 (nǎr - where), which we will cover in the next lesson, inherently make a sentence a question. Adding 吗 at the end would be redundant and grammatically incorrect.
Think of it this way:
你是谁？(Nǐ shì shéi?) - Who are you? (Correct content question)你是老师吗？(Nǐ shì lǎoshī ma?) - Are you a teacher? (Correct yes/no question)你是谁吗？- (Incorrect)
The article from the Chinese Grammar Wiki you read earlier makes this exact point. It's a common mistake for learners, so being aware of it now will help you build correct grammatical habits from the start.
Conclusion
You've now added another fundamental tool to your Mandarin toolkit. You can take the declarative sentences you already know how to build and, with the simple addition of one particle, turn them into questions seeking confirmation.
Key Takeaways:
- The
+ 吗Rule: To form a yes/no question, add the neutral-tone particle 吗 (ma) to the end of a statement. The word order does not change. - Verb-Centric Answers: There is no single word for "yes" or "no." You answer a
吗question by repeating the main verb in its affirmative (是) or negative (不是) form. - No Redundancy: 吗 (ma) should not be used in a sentence that already contains another question word (like who, what, where).
In our next lesson, we will tackle those other question words. While 吗 helps you ask "is it or isn't it?", words like 什么 (shénme - what), 谁 (shéi - who), and 哪儿 (nǎr - where) will allow you to ask for specific pieces of information, opening up a much wider range of conversational possibilities.
