Asking "Can you?" with Potential Complements

Use Verb + 得 + Result + 吗 to ask if an action's outcome is possible, like 'Can you finish eating?'

Grammar Rule in 30 Seconds

Use 'Verb + 得/不 + Complement' to ask if someone has the ability or condition to finish an action.

  • Use 'Verb + 得 + Complement' for affirmative ability (e.g., {听得懂|tīng de dǒng} - can understand).
  • Use 'Verb + 不 + Complement' for negative inability (e.g., {听不懂|tīng bù dǒng} - cannot understand).
  • Use 'Verb + 得 + Complement + 吗?' to ask if the action is possible (e.g., {看得见吗|kàn de jiàn ma}?).
Verb + 得/不 + Complement + (吗?)

Overview

In Chinese grammar, expressing whether an action can achieve a particular result is fundamental. Unlike English, where you might simply add "can" before a verb, Chinese frequently integrates this possibility directly into the verb structure. This grammatical pattern is known as the Potential Complement.

Specifically, when you ask "Can you do it?" or "Is it possible to achieve X?", you're using the Potential Complement Question Form. This structure is used to inquire about the feasibility, capacity, or achievability of an action's outcome, rather than general ability or permission. It allows for a precise query: "Will the action Verb successfully lead to the Result Complement?"

Consider situations like asking if someone can hear you, if they can understand a lecture, or if a dish is even possible to finish. These are all perfect scenarios for the potential complement question. This construction makes your Chinese sound more natural and native, providing a nuanced distinction that 能 (néng) or 可以 (kěyǐ) alone cannot always capture.

At its core, this structure assesses the potential for a specific outcome.

How This Grammar Works

At the heart of the potential complement lies the particle 得 (de) (sometimes referred to as in this specific grammatical context, though de is more common when explaining the structure) and its negative counterpart 不 (bù). These particles act as a bridge between a main verb and a Result Complement (RC), indicating whether the result of the action is achievable or not. For questions, 得 (de) signifies that the result can be achieved, while 不 (bù) signals that it cannot.
This system is a direct extension of Chinese Result Complements, which describe the outcome of an action.
To grasp the potential complement, you must first understand Result Complements. These are verbs or adjectives that immediately follow a main verb to describe the outcome or state resulting from the action. For example, in 吃饱 (chī bǎo) (eat until full), 饱 (bǎo) is the result complement.
In 看见 (kàn jiàn) (see and perceive), 见 (jiàn) is the result complement. When you introduce 得 (de) or 不 (bù) between the main verb and its result complement, you transform the statement from describing a result to commenting on the potential of achieving that result.
When 得 (de) is inserted, it creates Verb + 得 + Result Complement, indicating that the action can achieve the specified result. Conversely, Verb + 不 + Result Complement indicates that the action cannot achieve the result. For instance, 吃得饱 (chī de bǎo) means "can eat until full," while 吃不饱 (chī bu bǎo) means "cannot eat until full." The 得 (de) particle here does not carry a lexical meaning of "can" or "able to"; instead, it functions purely as a grammatical marker of positive potential, linking the verb to its achievable result.
This is a fundamental linguistic principle in Chinese: modifying the verb-object relationship to express nuance in outcome and possibility.
Consider the difference: 你看懂了 (Nǐ kàn dǒng le) means "You understood (by watching/reading)." This is a statement of fact about a completed action. However, 你看得懂 (Nǐ kàn de dǒng) means "You can understand (by watching/reading)." This shifts the focus from a past result to a present potential. The presence of 得 (de) makes all the difference, transforming a simple result into a statement about its attainability.
This distinction is crucial for A1 learners, as it clarifies when to use and when to omit it.
Here are some common verb + result complement pairs that frequently appear in potential complements:
| Verb | Result Complement | Combined Meaning | Potential (Positive) | Potential (Negative) |
|:-----|:------------------|:------------------------|:---------------------|:---------------------|
| 看 (kàn) (see) | 见 (jiàn) (perceive) | 看见 (kàn jiàn) (see/spot) | 看得见 (kàn de jiàn) | 看不见 (kàn bu jiàn) |
| 听 (tīng) (listen) | 懂 (dǒng) (understand) | 听懂 (tīng dǒng) (understand by listening) | 听得懂 (tīng de dǒng) | 听不懂 (tīng bu dǒng) |
| 吃 (chī) (eat) | 完 (wán) (finish) | 吃完 (chī wán) (finish eating) | 吃得完 (chī de wán) | 吃不完 (chī bu wán) |
| 找 (zhǎo) (look for) | 到 (dào) (reach/obtain) | 找到 (zhǎo dào) (find) | 找得到 (zhǎo de dào) | 找不到 (zhǎo bu dào) |
These structures form the building blocks for asking questions about potential. The verb and its result complement form a tight unit, with or nestled between them to indicate possibility.

Formation Pattern

1
Forming questions with potential complements primarily involves two methods: using 吗 (ma) or the affirmative-negative (A-not-A) construction. Both methods inquire about the achievability of a result, but the A-not-A form can sometimes convey a slightly more direct or expectant tone.
2
1. The 吗 (ma) Method (General Question)
3
This is the simplest way to form a yes/no question about potential. You take the positive potential complement structure and append 吗 (ma) at the end of the sentence.
4
Structure: Verb + 得 + Result Complement + (Object) + 吗?
5
The Object of the verb, if present, usually comes after the Verb + 得 + Result Complement phrase, or it can be placed at the very beginning of the sentence as a topic.
6
| Component | Example | Pinyin | Translation |
7
|:--------------------------|:-----------------------------------------|:------------------------------|:------------------------------|
8
| Verb + + RC | 看得见 | kàn de jiàn | can see |
9
| | 吗? | ma? | ? |
10
| Full Question | 看得见吗? | Kàn de jiàn ma? | Can you see (it)? |
11
| With Object (after RC) | 听得懂老师的话吗? | Tīng de dǒng lǎoshī de huà ma? | Can you understand the teacher's words? |
12
| With Object (topic) | 那本书你买得到吗? | Nà běn shū nǐ mǎi de dào ma? | That book, can you buy it (successfully)? |
13
Example Sentences:
14
这个房间看得见外面吗? (Zhège fángjiān kàn de jiàn wàimiàn ma?) – Can this room see outside (is the view clear)?
15
今天的作业你写得完吗? (Jīntiān de zuòyè nǐ xiě de wán ma?) – Can you finish today's homework?
16
这么吵的地方你听得见我说话吗? (Zhème chǎo de dìfang nǐ tīng de jiàn wǒ shuōhuà ma?) – In such a noisy place, can you hear me speak?
17
2. The Affirmative-Negative (A-not-A) Method (Direct Question)
18
This method explicitly states both the positive and negative potential, asking "Can it be done or not?" It often feels more direct than the 吗 (ma) question.
19
Structure: Verb + 得 + Result Complement + Verb + 不 + Result Complement?
20
Just like with the 吗 (ma) form, the Object comes after the complement phrase or topicalized at the beginning.
21
| Component | Example | Pinyin | Translation |
22
|:----------------------------|:-----------------------------------------|:----------------------------------|:------------------------------------|
23
| Verb + + RC (Positive) | 听得懂 | tīng de dǒng | can understand |
24
| Verb + + RC (Negative) | 听不懂 | tīng bu dǒng | cannot understand |
25
| Full Question | 听得懂听不懂? | Tīng de dǒng tīng bu dǒng? | Can you understand or not? |
26
| With Object (after RC) | 这些汉字你认得出来认不出来? | Zhèxiē hànzì nǐ rèn de chūlái rèn bu chūlái? | These characters, can you recognize them or not? |
27
| With Object (topic) | 那么远的地方他看得见看不见? | Nàme yuǎn de dìfang tā kàn de jiàn kàn bu jiàn? | That far place, can he see (it) or not? |
28
Example Sentences:
29
你吃得完吃不完? (Nǐ chī de wán chī bu wán?) – Can you finish eating or not?
30
外面太黑了,你看得清看不清? (Wàimiàn tài hēi le, nǐ kàn de qīng kàn bu qīng?) – It's too dark outside, can you see clearly or not?
31
这个新的软件,你学得会学不会? (Zhège xīn de ruǎnjiàn, nǐ xué de huì xué bu huì?) – This new software, can you learn it or not?
32
Notice that in the A-not-A structure, the second Verb can sometimes be omitted if the Result Complement is identical to the first Result Complement and there's no ambiguity (e.g., 听得懂不懂?). However, for A1 learners, it is always safer and clearer to use the full Verb + 得 + RC + Verb + 不 + RC form to avoid confusion.
33
Object Placement Rule Reminder:
34
The object generally follows the Verb + 得 + Result Complement phrase. For instance, 你看得懂这本书吗? (Nǐ kàn de dǒng zhè běn shū ma?) (Can you understand this book?).
35
Alternatively, the object can be topicalized, placed at the beginning of the sentence before the subject and verb phrase. For example, 这本书你看得懂吗? (Zhè běn shū nǐ kàn de dǒng ma?) (This book, can you understand it?). Never place the object between the verb and or between and the result complement.

When To Use It

Use the potential complement question form when you want to inquire about the feasibility of an action achieving a specific, concrete result or outcome. This is its core function, distinguishing it from general questions of ability or permission. It's particularly common in situations involving sensory perception, cognitive understanding, physical capacity, or the successful completion of a task.
  • Sensory Perception (Can you see/hear/smell/taste it?):
These are among the most frequent uses. You're asking if the physical act of seeing or hearing will result in perception.
  • 这里的光线不好,你看得清楚吗? (Zhèlǐ de guāngxiàn bù hǎo, nǐ kàn de qīngchǔ ma?) – The lighting here is bad, can you see clearly?
  • 我说话声音小,你听得见吗? (Wǒ shuōhuà shēngyīn xiǎo, nǐ tīng de jiàn ma?) – My voice is quiet, can you hear me?
  • 这么远,你闻得到花香吗? (Zhème yuǎn, nǐ wén de dào huāxiāng ma?) – It’s so far, can you smell the flowers?
  • Cognitive Understanding (Can you understand/recognize it?):
This applies to understanding spoken or written language, or recognizing something. The result is 'understanding' or 'recognition'.
  • 老师说得太快,你听得懂吗? (Lǎoshī shuō de tài kuài, nǐ tīng de dǒng ma?) – The teacher speaks too fast, can you understand?
  • 这些旧照片你认得出来是谁吗? (Zhèxiē jiù zhàopiàn nǐ rèn de chūlái shì shéi ma?) – These old photos, can you recognize who they are?
  • 这本书很难,你读得懂吗? (Zhè běn shū hěn nán, nǐ dú de dǒng ma?) – This book is very difficult, can you read and understand it?
  • Completion or Achievement (Can you finish/get/succeed?):
When the action aims for a specific completion or successful acquisition.
  • 这么多菜,我们吃得完吗? (Zhème duō cài, wǒmen chī de wán ma?) – So many dishes, can we finish eating them?
  • 你想买的那张票,现在还买得到吗? (Nǐ xiǎng mǎi de nà zhāng piào, xiànzài hái mǎi de dào ma?) – That ticket you want to buy, can you still get it now?
  • 这个工作你一个人做得了吗? (Zhège gōngzuò nǐ yīgè rén zuò de liǎo ma?) – This job, can you do it by yourself (successfully)?
  • Physical Feasibility/Capacity (Can you move it/carry it?):
Inquiring if a physical action is possible due to constraints like weight, space, or strength.
  • 这个箱子太重了,你拿得动吗? (Zhège xiāngzi tài zhòng le, nǐ ná de dòng ma?) – This box is too heavy, can you lift it?
  • 我的行李太多了,这个车装得下吗? (Wǒ de xínglǐ tài duō le, zhège chē zhuāng de xià ma?) – I have too much luggage, can this car fit it?
  • Contrast with 能 (néng) and 可以 (kěyǐ):
It's critical to understand the distinction. 能 (néng) and 可以 (kěyǐ) generally ask about permission, general ability, or availability of conditions. The potential complement asks about the achievability of a result.
  • 你能去吗? (Nǐ néng qù ma?) – Can you go? (Are you allowed to? Do you have time? Are you physically capable of the act of going?)
  • 你走得了吗? (Nǐ zǒu de liǎo ma?) – Can you leave? (Is it physically possible to depart now? Are there obstacles preventing your departure?)
The latter focuses on the successful completion of the act of leaving despite potential hindrances, while the former is more about general permission or capacity to undertake the action.

Common Mistakes

Beginner and even intermediate learners frequently make specific errors when using potential complements in questions. Understanding these pitfalls will help you avoid sounding unnatural or being misunderstood.
  1. 1Confusing 得 (de) with 能 (néng)/可以 (kěyǐ):
This is perhaps the most common mistake. While 能 (néng) and 可以 (kěyǐ) translate to "can," they primarily indicate permission, general ability, or objective possibility (conditions allowing). The potential complement, however, is about the subjective or objective achievability of a specific result through an action. Adding 能 (néng) or 可以 (kěyǐ) before a potential complement is usually redundant and often sounds awkward, like saying "can be able to do."
  • Incorrect: 你能不能看得见吗? (Nǐ néng bù néng kàn de jiàn ma?) – This is a "double can." If you use or 可以, you shouldn't combine it directly with Verb + 得 + RC unless you intend to specifically emphasize both a general ability and the result's achievability, which is rare for A1.
  • Correct: 你看得见吗? (Nǐ kàn de jiàn ma?) – Can you see (perceive)? (Focus on result)
  • Correct: 你能来吗? (Nǐ néng lái ma?) – Can you come? (Focus on general ability/permission).
  1. 1Incorrect Negation with 没 (méi):
A crucial rule: Potential complements (positive or negative) always use 不 (bù) for negation, never 没 (méi). 没 (méi) is reserved for negating past actions or the existence of something. Asking about potential is always about a present or future possibility.
  • Incorrect: 你听得懂没? (Nǐ tīng de dǒng méi?)
  • Correct: 你听得懂听不懂? (Nǐ tīng de dǒng tīng bu dǒng?)
  • Correct: 你听得懂吗? (Nǐ tīng de dǒng ma?)
  1. 1Misplacing the Object:
The object of the verb must not come between the verb and 得 (de), or between 得 (de) and the result complement. This is a rigid structure.
  • Incorrect: 你吃得饭完吗? (Nǐ chī de fàn wán ma?) (The object 饭 (fàn) is in the wrong place).
  • Correct: 你吃得完饭吗? (Nǐ chī de wán fàn ma?) (Object after the complement phrase).
  • Correct: 饭你吃得完吗? (Fàn nǐ chī de wán ma?) (Object topicalized at the beginning).
  1. 1Using Potential Complements with Verbs Lacking a Clear Result:
Not all verbs can take a potential complement. Only verbs that can combine with a result complement to describe a specific, discernible outcome are suitable. Verbs expressing states, desires, or general actions without a definable end-state typically do not use this structure.
  • Incorrect: 你跑得快吗? (Nǐ pǎo de kuài ma?) – While 快 (kuài) is an adjective, 跑 (pǎo) doesn't have a result like 完 (wán) or 懂 (dǒng). Here, 得 (de) is a descriptive complement (跑得很快 (pǎo de hěn kuài) – runs very fast), which is a different grammar point. For speed or general ability, you'd use or .
  • Correct: 你会游泳吗? (Nǐ huì yóuyǒng ma?) – Can you swim? (游泳 (yóuyǒng) – to swim, is a skill, not an action with a potential complement result).
  1. 1Confusing with Simple Result Complements (V + RC + 了):
The presence of 得 (de) is the key differentiator for potential. Without it, you are merely stating that a result occurred in the past (了 (le)) or will occur.
  • 你看懂了吗? (Nǐ kàn dǒng le ma?) – Did you understand (by reading/watching)? (Asks about a completed action/result).
  • 你看得懂吗? (Nǐ kàn de dǒng ma?) – Can you understand (by reading/watching)? (Asks about potential).
A common error for A1 learners is to use V + RC + 了 when they mean to ask about potential, losing the nuanced meaning.

Real Conversations

In everyday Chinese, potential complement questions are ubiquitous, especially when interacting with others about their capabilities or external conditions. They reflect a natural way of assessing feasibility. Here are examples in realistic contexts:

S

Scenario 1

In a restaurant, ordering food.

- A: 服务员,这些菜我们两个人吃得完吗? (Fúwùyuán, zhèxiē cài wǒmen liǎng gè rén chī de wán ma?)

(Waiter, can the two of us finish all these dishes?)

- B: 放心,吃得完。 (Fàngxīn, chī de wán.)

(Don't worry, you can finish them.)

S

Scenario 2

On a video call with a bad connection.

- A: 喂?你听得见我说话吗? (Wéi? Nǐ tīng de jiàn wǒ shuōhuà ma?)

(Hello? Can you hear me speak?)

- B: 不太清楚,你再说一遍听得清吗? (Bù tài qīngchǔ, nǐ zài shuō yī biàn tīng de qīng ma?)

(Not very clear, if you say it again, will I be able to hear clearly?)

S

Scenario 3

Discussing homework or a difficult text.

- A: 这篇课文很难,你翻译得懂吗? (Zhè piān kèwén hěn nán, nǐ fānyì de dǒng ma?)

(This text is very difficult, can you translate and understand it?)

- B: 有点儿难,我看得懂一些,但不是全部。 (Yǒudiǎnr nán, wǒ kàn de dǒng yīxiē, dàn bù shì quánbù.)

(It's a bit hard. I can understand some, but not all.)

S

Scenario 4

Making plans to meet up in a crowded place.

- A: 火车站人太多了,你找得到我吗? (Huǒchēzhàn rén tài duō le, nǐ zhǎo de dào wǒ ma?)

(The train station has too many people, can you find me?)

- B: 你告诉我你在哪个出口,我就找得到。 (Nǐ gàosù wǒ nǐ zài nǎge chūkǒu, wǒ jiù zhǎo de dào.)

(If you tell me which exit you're at, then I can find you.)

These examples illustrate that the potential complement question isn't just for textbooks. It's a natural, efficient way to check on the practical outcomes of actions in daily life. Native speakers use these structures to confirm if a result is practically achievable under current circumstances, often implying a concern for external conditions or inherent difficulty, not just someone's personal skill level.

Quick FAQ

  • Q: Can I use Verb + 得 + Result Complement for any verb?

No. It's only for verbs that can logically combine with a Result Complement to express a specific, achievable outcome. For example, you can't say 喜欢得懂 (xǐhuān de dǒng) because 喜欢 (xǐhuān) (to like) doesn't have a result that 懂 (dǒng) could describe. If a verb doesn't have a natural result complement, you likely cannot form a potential complement with it.

  • Q: What if I just say V + 吗? (V ma?)?

V + 吗? simply asks if you are doing the action or want to do the action. For instance, 吃吗? (Chī ma?) means "Are you eating?" or "Do you want to eat?" It does not inquire about the ability to complete or achieve a result from the action. For that, you absolutely need the potential complement structure like 吃得完吗? (Chī de wán ma?).

  • Q: Is the A-not-A question form (V + 得 + RC + V + 不 + RC?) rude?

Not at all. It's a very common and natural way to ask. It can sometimes sound more direct or emphasize the need for a clear yes/no answer, but it's not considered impolite. It's functionally similar to asking "Can you or can't you?" in English without the added aggressive tone.

  • Q: When should I use 得 (de) vs. 不 (bù) in potential complements?

得 (de) indicates positive potential (the result can be achieved). 不 (bù) indicates negative potential (the result cannot be achieved). For questions, you'll use in the positive part of the question (看得见吗? or 看得见看不见?). When answering negatively, you'll use (看不见。).

  • Q: Why is it important to learn this structure, especially for beginners?

Mastering the potential complement system, even at A1, immediately makes your Chinese sound more nuanced and native. It demonstrates an understanding of how Chinese expresses possibility beyond simple 能 (néng) or 可以 (kěyǐ). It’s especially practical for common daily interactions like asking for clarification (听得懂吗?), verifying perception (看得见吗?), or assessing practical tasks (做得完吗?), which are all essential for basic communication.

  • Q: Can I shorten the A-not-A form, like 听得懂不懂? (Tīng de dǒng bu dǒng?)?

Yes, you often hear this shortening in colloquial speech, where the second verb is omitted if it's clear from context. However, for A1 learners, it's recommended to stick to the full form (听得懂听不懂?) to ensure clarity and avoid potential confusion. As you become more comfortable, you can naturally pick up the shortened version.

  • Q: Does 得 (de) have a special tone here?

In this grammatical context, is almost always pronounced in the neutral tone (de). While can also be pronounced (meaning 'to get/obtain') or děi (meaning 'must'), for the potential complement structure, it's consistently de.

Focus on the Result

Always ask yourself: what is the result of this action? That is your complement.
⚠️

Don't use '能'

If you are talking about the result of an action, '能' is usually wrong.
🎯

Use with '吗'

The easiest way to practice is to turn your statements into questions.
💬

Be direct

Using these structures is very common in Chinese to be clear about your limits.

Smart Tips

Check if you are talking about a result. If yes, use V+不+C.

我不能做完 我做不完

The second verb is likely the complement.

听懂 听得懂
