Overview
In Chinese grammar, expressing concepts like 'want' or 'can' is relatively direct. However, a more nuanced idea is willingness—the internal consent to do something, especially when it involves effort, sacrifice, or overcoming a bit of reluctance. This is the specific job of the modal verb 肯 (kěn).
It doesn't just mean you want to do something; it means you've decided you're willing to do it.
Think of it as the difference between desire and consent. You might 想 (xiǎng) (want) to eat ice cream, an easy, pleasant desire. But if your friend asks you to help them move apartments on a hot Saturday, your agreement isn't about pure desire—it's about willingness.
You 肯 (kěn) help them, signifying you've accepted the inconvenience and are consciously choosing to act. 肯 (kěn) is the 'yes' that carries the weight of a considered choice.
This verb is incredibly revealing about a person's attitude. It tells your listener not just what you'll do, but also gives insight into the internal calculation behind the decision. It often implies that there was a reason not to do the action, but you've overcome that barrier.
Understanding 肯 (kěn) is crucial for moving beyond simple statements of fact and into the psychological subtleties of communication. Its negative form, 不肯 (bù kěn) (unwilling/refuses to), is one of the most common ways to describe stubbornness, making it a high-frequency word in everyday complaints and negotiations.
How This Grammar Works
肯 (kěn) functions to add a layer of meaning about the subject's disposition towards an action. It's placed directly before the main verb to signal that the subject has the volition or resolve to perform that verb's action. It’s not about ability (能 néng) or simple intent (要 yào), but specifically about the internal green light of consent.肯 itself offers a clue. It's often interpreted as a pictograph related to 肉 (ròu) (meat) and 骨 (gǔ) (bone). An ancient meaning was related to gnawing meat from a bone, an action that requires persistence and effort.肯 do something, you're implying you're ready to exert the necessary effort or accept the associated cost.- Fact:
他去上海。
Tā qù Shànghǎi. (He goes to Shanghai.)- Desire:
他想去上海。
Tā xiǎng qù Shànghǎi. (He wants to/would like to go to Shanghai.)- Ability/Possibility:
他能去上海。
Tā néng qù Shànghǎi. (He can go to Shanghai.)- Willingness:
他肯去上海。
Tā kěn qù Shànghǎi. (He is willing to go to Shanghai.)肯 (kěn) operates in a psychological space. When you use it, you're commenting on the subject's internal decision-making. 我肯帮你 (Wǒ kěn bāng nǐ)—I am willing to help you—says much more than 我帮你 (Wǒ bāng nǐ).Formation Pattern
肯 (kěn) in sentences is straightforward and follows the standard Subject-Modal-Verb-Object pattern common to all Chinese modal verbs. It does not change for tense or person. Its primary forms are affirmative, negative, and A-not-A questions.
肯 (kěn):
肯 + Verb + (Object) | 他肯学中文。 | Tā kěn xué Zhōngwén. (He is willing to learn Chinese.) |
我肯帮你搬家。 | Wǒ kěn bāng nǐ bānjia. (I am willing to help you move.) |
不肯 + Verb + (Object) | 她不肯道歉。 | Tā bù kěn dàoqiàn. (She is unwilling to/refuses to apologize.) |
我的猫不肯吃药。 | Wǒ de māo bù kěn chī yào. (My cat refuses to take medicine.) |
肯不肯 + Verb + (Object)? | 你肯不肯借我钱？ | Nǐ kěn bù kěn jiè wǒ qián? (Are you willing to lend me money?) |
老板肯不肯涨工资？ | Lǎobǎn kěn bù kěn zhǎng gōngzī? (Is the boss willing to raise salaries?) |
吗 (ma) Question | Subject + 肯 + Verb + (Object) + 吗? | 你肯帮忙吗？ | Nǐ kěn bāngmáng ma? (Are you willing to help?) |
不肯 (bù kěn). You must not use 没 (méi). This is a core rule for modal verbs expressing a state of mind or disposition. 不 (bù) negates the state of being willing, regardless of whether you're talking about the past, present, or future. For example, 他昨天不肯来 (Tā zuótiān bù kěn lái) means "He was unwilling to come yesterday."
肯不肯 (kěn bù kěn) A-not-A structure is the most common and idiomatic way to ask a yes/no question about willingness. While using 吗 (ma) is grammatically correct, it can sometimes sound a little less natural or more formal. In conversation, you'll hear kěn bù kěn far more frequently.
肯 (kěn) is a pillar of stability. It remains 肯 whether the subject is 我, 你, 他们, or 总统. Time is indicated by context words like 昨天 (zuótiān), 现在 (xiànzài), or particles like 了 (le). For example, 他终于肯吃饭了 (Tā zhōngyú kěn chīfàn le) means "He is finally willing to eat."
When To Use It
肯 (kěn) in situations where the subject’s cooperative attitude or consent is the most important part of the message. It excels in contexts where an action is not a given and requires a conscious, often concessionary, decision.肯 (kěn) perfectly captures that sense of concession.我请了他三次，他终于肯来了。
Wǒ qǐngle tā sāncì, tā zhōngyú kěn lái le.如果你肯教我，我愿意付学费。
Rúguǒ nǐ kěn jiāo wǒ, wǒ yuànyì fù xuéfèi.不肯)不肯 (bù kěn), is extremely common and powerful. It describes a willful refusal to do something. It’s stronger and more personal than simply saying someone 不要 (bú yào) (doesn't want to). It implies they have made a firm internal decision to resist.那个小孩子脾气很坏，不肯跟人分享玩具。
Nàge xiǎo háizi píqì hěn huài, bù kěn gēn rén fēnxiǎng wánjù.无论我们怎么劝他，他就是不肯去医院。
Wúlùn wǒmen zěnme quàn tā, tā jiùshì bù kěn qù yīyuàn.肯 (kěn) can be used to praise someone's character. Saying someone 肯 do something that benefits others portrays them as generous, hard-working, and cooperative. It highlights their readiness to go the extra mile.他这个人特别好，很肯帮人。
Tā zhège rén tèbié hǎo, hěn kěn bāng rén.她很聪明，也肯努力，所以进步很快。
Tā hěn cōngmíng, yě kěn nǔlì, suǒyǐ jìnbù hěn kuài.肯 (kěn) is frequently used in conditional sentences with words like 只要 (zhǐyào) (as long as) and 如果 (rúguǒ) (if) to frame willingness as the key condition for a certain outcome.只要你肯学，没有什么学不会的。
Zhǐyào nǐ kěn xué, méiyǒu shé me xué bù huì de.Common Mistakes
肯 (kěn) for Simple Desires or Wants肯 (kěn) implies overcoming reluctance; for pure, unconflicted desires, you should use 想 (xiǎng).- Incorrect:
我周末很肯去看电影。(I am very willing to go see a movie this weekend.) - Why it's wrong: Going to the movies is usually a pleasant activity. Using
肯makes it sound like a chore you've begrudgingly agreed to. - Correct:
我周末很想去看电影。(Wǒ zhōumò hěn xiǎng qù kàn diànyǐng.) (I really want to go see a movie this weekend.)
不肯 (bù kěn) with 不要 (bú yào)不要 is a direct rejection or a command ("don't"). 不肯 is a description of a stubborn internal state of refusal.- Context: A friend offers you a drink you don't like.
谢谢，我不要这个，我喝水就好。 (Xièxiè, wǒ bú yào zhège, wǒ hē shuǐ jiù hǎo.) (Thanks, I don't want this one, I'll just have water.)
谢谢，我不肯这个。 This sounds confrontational and strange, as if they are trying to force you and you are resisting.老板让他加班，但是他不肯。 (Lǎobǎn ràng tā jiābān, dànshì tā bù kěn.) (The boss asked him to work overtime, but he refused.)不肯 is perfect here because it describes his willful opposition to the request.没 (méi) as the Negative Form不 (bù), even in the past.- Incorrect:
昨天他没肯帮我。 - Why it's wrong:
没negates completed actions (没有来 méiyǒu lái- did not come).肯describes an internal state, not an action itself. The state of unwillingness existed yesterday. - Correct:
昨天他不肯帮我。(Zuótiān tā bù kěn bāng wǒ.) (Yesterday, he was unwilling to help me.)
肯 for Simple Preferences喜欢 (xǐhuān) is the correct choice. 肯 is too heavy and implies a high-stakes decision.- Incorrect:
晚饭我肯吃米饭，不肯吃面条。 - Why it's wrong: This makes your meal choice sound like a major concession or a point of stubborn refusal. It's unnatural for a simple preference.
- Correct:
晚饭我喜欢吃米饭，不喜欢吃面条。(Wǎnfàn wǒ xǐhuān chī mǐfàn, bù xǐhuān chī miàntiáo.) (For dinner, I like to eat rice, not noodles.)
Real Conversations
To really understand 肯 (kěn), let's see how it appears in natural, everyday situations. Notice how it often revolves around negotiation, favors, and effort.
Scenario 1
- A: 今天晚饭我做了，你肯洗碗吗？
Jīntiān wǎnfàn wǒ zuòle, nǐ kěn xǐwǎn ma?
(I made dinner tonight, are you willing to wash the dishes?)
The use of 肯 acknowledges that washing dishes is a chore no one is excited about.*
- B: 行啊，这我肯定肯。你做饭我洗碗，公平。
Xíng a, zhè wǒ kěndìng kěn. Nǐ zuòfàn wǒ xǐwǎn, gōngpíng.
(Sure, I'm definitely willing to do that. You cook, I wash dishes—that's fair.)
肯定肯 (kěndìng kěn - definitely willing) adds strong emphasis.*
Scenario 2
- A: 你儿子最近怎么样？
Nǐ érzi zuìjìn zěnme yàng?
(How's your son lately?)
- B: 别提了，让他去理发，他怎么说都不肯去，愁死我了。
Biétíle, ràng tā qù lǐfà, tā zěnme shuō dōu bù kěn qù, chóu sǐ wǒ le.
(Don't even mention it. I want him to get a haircut, but no matter what I say, he refuses to go. It's worrying me to death.)
不肯 is the perfect verb to describe a child's stubborn defiance.*
Scenario 3
- Friend A: 我车在路上坏了，你肯开车来接我一下吗？😭
Wǒ chē zài lùshàng huàile, nǐ kěn kāichē lái jiē wǒ yíxià ma? 😭
(My car broke down on the road, would you be willing to drive and pick me up?)
肯 here is polite because it acknowledges the request is a major inconvenience.*
- Friend B: 当然肯！别急，发个定位给我，我马上到。
Dāngrán kěn! Bié jí, fā gè dìngwèi gěi wǒ, wǒ mǎshàng dào.
(Of course I'm willing! Don't worry, send me your location, I'll be there right away.)
Quick FAQ
