Lesson 32

Asking Age with 岁 and 多大

Recommended resources

Hello! In our last lesson, we completed our tour of HSK 1 time expressions by learning the words for different parts of the day. You are now equipped to specify when an event happens with considerable precision, always following the logical "big to small" rule.

Today, we will address a related but distinct topic: asking and answering questions about age. This is a fundamental conversational skill that builds directly on your knowledge of numbers. Our learning goal is to master the use of 岁 (suì) for stating age and 多大 (duō dà) as the primary way to ask "How old are you?". Crucially, you'll also learn why this isn't the only way to ask and how the question changes depending on whom you are addressing.

Stating Age: The Role of 岁 (suì)

First, let's look at how to answer a question about age. The key character here is 岁 (suì), which functions like "years old" in English. The sentence structure is straightforward and efficient.

The pattern is: Subject + Number + 岁 (suì)

For example:

  • 我三十五岁。(Wǒ sānshíwǔ suì.) - I am 35 years old.
  • 他儿子两岁。(Tā érzi liǎng suì.) - His son is two years old.

A critical point to note is the absence of the verb 是 (shì). In English, we say "I am 35," but in Chinese, you do not say 我是三十五岁 (Wǒ shì sānshíwǔ suì). The structure is more direct: "I, 35 years old." This is an important grammatical pattern to internalize.

To hear the pronunciation and see this structure in action, please watch the beginning of this video from ChineseFor.Us.

This video provides a clear breakdown of asking and answering about age.

Focus on the first part, from the basic structure, where the presenter explains how to state your age using the Subject + Number + 岁 pattern.

For a quick textual reinforcement of this rule, you can refer to the "Flexi Classes" grammar page.

This guide offers a concise explanation of how to use 岁.

Read the section under the heading BASIC STRUCTURE. It lays out the pattern and provides a few clear examples. Notice again that the verb 是 is not used in the main examples.


Asking "How Old Are You?": Context is Key

Now for the main part of our lesson: asking the question. Unlike in English, Mandarin uses different phrases to ask "How old are you?" depending on the presumed age of the person you're speaking to. This reflects a greater degree of social nuance. For HSK 1, you need to know the two most common forms.

1. For Adults and Peers: 你多大? (Nǐ duō dà?)

This is the standard, neutral, and most common way to ask an adult or a teenager their age.

  • 你多大? (Nǐ duō dà?) - How old are you?

Let's break this down:

  • 你 (nǐ): you
  • 多 (duō): how
  • 大 (dà): big, large (in this context, old)

Literally, it translates to "You how big?". This is the go-to phrase for anyone who is clearly not a small child.

2. For Young Children: 你几岁? (Nǐ jǐ suì?)

When asking a young child (typically under 10), you should use a different phrase.

  • 你几岁? (Nǐ jǐ suì?) - How old are you?

The components are:

  • 你 (nǐ): you
  • 几 (jǐ): how many (used for expected small numbers, usually under 10)
  • 岁 (suì): years old

The use of 几 (jǐ) here is significant. It implies you expect the answer to be a small number. Using this question with an adult would sound condescending, as if you were talking to a child.

The following video segments clearly explain and demonstrate the use of both 多大 and 几岁.

Continuing with the same video from ChineseFor.Us.

First, watch the explanation of 多大 (duō dà), for asking adults, from this segment. Then, watch the following part which explains 几岁 (jǐ suì), for asking children, from this explanation. Pay close attention to the age ranges the presenter suggests for each phrase.

The article from ChineseFor.Us provides a solid written summary of these rules.

This article corresponds to the video you just watched and reinforces the grammar points.

Under the heading Grammar 2, please read the two subsections: (1) nǐ duō dà and (2) nǐ jǐ suì. This text explicitly lays out the rules for when to use each question form.


Visualizing the Difference

To consolidate this concept, the following image provides a perfect visual summary. It shows the three common ways to ask for age, mapped to the appropriate age group of the person being asked.

This image illustrates the three main ways to ask about age in Mandarin. From top to bottom: **多大 (duō dà)** for peers and adults, **几岁 (jǐ suì)** for children, and the more respectful **多大年纪 (duō dà niánjì)** for elders.

The image includes a third, more formal and respectful question for older people: 您多大年纪? (Nín duōdà niánjì?). This is outside the core HSK 1 requirements but is useful for context. It uses the polite "you" (您, nín) and the word for "age" (年纪, niánjì), signaling a higher level of deference.

Here is a typical exchange:

A: 你好!你叫什么名字? (Nǐ hǎo! Nǐ jiào shénme míngzì?)
B: 我叫大卫。 (Wǒ jiào Dàwèi.)
A: 大卫,你多大? (Dàwèi, nǐ duō dà?)
B: 我二十九岁。 (Wǒ èrshíjiǔ suì.)


Conclusion

You have now learned the essential vocabulary and grammar for discussing age. This completes the "Numbers, Dates, and Time" module. You can now count, tell time, state dates, and discuss age—a very practical set of skills.

Key Takeaways:

  • To state age, use the pattern: Subject + Number + 岁 (suì). The verb 是 (shì) is not used.
  • To ask an adult or peer their age, use 你多大? (Nǐ duō dà?).
  • To ask a young child their age (under ~10), use 你几岁? (Nǐ jǐ suì?).
  • The choice of question reflects social context and is an important distinction in Mandarin.

Next Lesson Preview:

In this lesson, you saw how 几 (jǐ) is used to ask a question where a small number is expected as the answer. This is just one side of the coin. The other question word for "how many/much" is 多少 (duōshao). In our next lesson, we will formally distinguish between 几 and 多少 and learn the rules for using them to ask about quantities in various contexts.
