会, 能, 可以: Three Ways to Say 'Can' in Mandarin

"I can eat spicy food" has three correct Chinese translations, and they mean three different things about you.

我会吃辣 (wǒ huì chī là) says you've developed a taste for it — you're the kind of person who orders the Sichuan menu. 我能吃辣 (wǒ néng chī là) says you can physically handle it without crying. 我可以吃辣 (wǒ kěyǐ chī là) says nothing is stopping you: no ulcer, no pregnancy, no dietary rule. Same English sentence. Three different social claims. Native speakers hear the difference immediately and silently re-parse when a learner picks the wrong one.

English collapses all of this into one word. Mandarin splits "can" into 会, 能, and 可以, and each one makes a specific claim about whether the ability is learned, situational, or permitted. Here's how to pick the right one without freezing up mid-sentence. (If you're still wrestling with why Mandarin tones feel impossible at first, this is the grammar-side sibling problem: small distinctions that carry big meaning.)

会 (huì) is your resumé verb

我会说中文 (wǒ huì shuō Zhōngwén) means "I can speak Chinese." This is the sentence you're building toward, and it's a classic 会 sentence because speaking a language is something you learned. You weren't born doing it. You studied, you failed, you got better. That trajectory is exactly what 会 describes.

Use 会 for anything on a résumé. Languages. Driving. Swimming. Playing an instrument. Cooking. If the question "how did you learn to do that?" has a reasonable answer, 会 is the verb you want. That's why Glossika calls 会 the "learned ability" modal, and why 我会游泳 (wǒ huì yóuyǒng) is how you say "I can swim."

Two bonus uses worth knowing. First, intensified with 很, 会 expresses skillfulness, not just competence. 我妻子很会做饭 (wǒ qīzi hěn huì zuò fàn) doesn't mean "my wife can cook," which would be a weird thing to brag about. It means "my wife is really good at cooking." The 很会 construction is a compliment. Second, 会 is the modal for future prediction: 明天会下雨 (míngtiān huì xiàyǔ) means "it'll rain tomorrow." Neither 能 nor 可以 does this job. If you're predicting the future, 会 is your only option.

One trap: 你能说中文吗 (nǐ néng shuō Zhōngwén ma?) is grammatical, but it sounds like you're asking whether conditions currently permit someone to speak Chinese, like you're checking if their jaw is wired shut. The natural question is 你会说中文吗 (nǐ huì shuō Zhōngwén ma?), meaning "do you know how to speak Chinese?" Learners default to 能 here because "are you able to" feels polite in English. In Mandarin, it feels like the wrong question.

能 (néng) is about right now

我病了，不能去 (wǒ bìngle, bùnéng qù) means "I'm sick, I can't go." Nothing has changed about what you know how to do. Nothing has changed about whether you have permission. The situation has changed. That's 能's whole job: describing what's possible given the current state of the world.

A good test: if you could add "today" or "right now" to the English sentence without changing the meaning, you probably want 能. 我今天不能游泳，手受伤了 (wǒ jīntiān bùnéng yóuyǒng, shǒu shòushāng le) means "I can't swim today, my arm is hurt." The person still knows how to swim (我会游泳), but the current situation blocks them. Migaku's breakdown of situational capability frames this well: 能 asks whether conditions allow it.

能 also handles capacity claims. 这个房间能住三个人 (zhège fángjiān néng zhù sān ge rén) means "this room fits three people." And there's a fun one from Written Chinese's breakdown: 他真能吃 (tā zhēn néng chī) means "he can really put it away" — it's about the sheer quantity he's physically capable of eating. Compare that to 他真会吃 (tā zhēn huì chī), which means "he's a foodie," someone with cultivated taste. Same three characters apart. Different person entirely.

可以 (kěyǐ) is a social green light

老师，我可以去洗手间吗 (lǎoshī, wǒ kěyǐ qù xǐshǒujiān ma?) means "Teacher, may I go to the bathroom?" This is the 可以 prototype: you're asking a human (or a rule, or a sign) for permission. Someone with authority over the situation has to give you the green light.

可以 shows up wherever permission is the relevant question. 这里可以停车 (zhèlǐ kěyǐ tíngchē) means "parking's allowed here." The sign permits it. 我可以开窗吗 (wǒ kěyǐ kāi chuāng ma?) means "may I open the window?" You're asking the other person in the room. It also extends to suggestions, where the permission framing relaxes into advice: 你可以试试这个方法 (nǐ kěyǐ shìshi zhège fāngfǎ) means "you can try this method." You're telling someone an option is open to them.

The 60-second decision tree

Someone asks you 你会弹吉他吗 (nǐ huì tán jítā ma?) and your brain blanks on which modal they used. Over time, the answer gets automatic. While you're building the reflex, run three questions in order:

1. Is this about a learned skill or a future prediction? If yes, use 会.
2. Is this about the situation right now — capacity, conditions, whether it's physically possible? If yes, use 能.
3. Is this about permission, rules, or signs? If yes, use 可以.

Run "Can I borrow your charger?" through it. Learned skill? No. Situation right now? Maybe, but the real question is permission, so it's 可以. 我可以借你的充电器吗 (wǒ kěyǐ jiè nǐ de chōngdiànqì ma?).

Run "Can you play guitar?" through it. Learned skill? Yes, clearly. Done. 你会弹吉他吗 (nǐ huì tán jítā ma?).

Run "Can you make it to dinner at seven?" Not a learned skill. Not about permission. It's about whether the situation (traffic, schedule, babysitter) permits it. 你七点能来吃饭吗 (nǐ qī diǎn néng lái chī fàn ma?).

The tree is a crutch for when you freeze up. Over a few months, you stop running it consciously. Keep it in your pocket until the reflex is built.

The over-politeness trap

English speakers reach for 可以 way too often, because it maps onto "may I" and "is it okay if." I did this for months. In English, we soften almost every request by framing it as permission: "May I have a minute of your time?" "Is it okay if I borrow this?" "Can I ask a question?" In Mandarin, defaulting to 可以 in these contexts sounds like you're asking HR if you're allowed to do your job.

The giveaway shows up at work. Saying 我可以帮你吗 (wǒ kěyǐ bāng nǐ ma?), meaning "may I help you?", feels polite in an English-speaker way. It lands in Mandarin like you're asking permission to be helpful, which is a weird social move. The more natural version is 要不要我帮忙 (yào bú yào wǒ bāngmáng?), meaning "do you want a hand?" If ability is really the question, 我能帮你吗 (wǒ néng bāng nǐ ma?) works, meaning "can I help you (am I able to)?"

This is an observation, not a research finding, and it's more of an intermediate problem than a beginner one. A beginner who says 可以 everywhere comes across as trying hard. An intermediate learner who keeps doing it three years in sounds like they never made the jump from translating English to thinking in Mandarin.

Mistake gallery: what natives actually hear

你可以说中文吗 is grammatical. It also sounds like you're asking whether someone is permitted to speak Chinese, which is a strange thing to check. The natural version is 你会说中文吗 (nǐ huì shuō Zhōngwén ma?). Here are three more sentences that are technically correct but socially audible:

• 我能游泳 as a standalone statement reads as "I have the capacity to swim right now." Fine if you're pointing at a pool and confirming conditions are okay. Weird if you just mean you know how to swim. Use 我会游泳.
• 我不能来 is grammatical, but Migaku notes that the native reflex for "I can't come" is 我来不了 (wǒ lái bù liǎo). The 来不了 potential-complement construction carries the "I'm blocked from making it" meaning more naturally than 不能.
• 我不会喝酒 vs 我不能喝酒 is a subtle but real split. 我不会喝酒 (wǒ bú huì hē jiǔ) means "I don't drink," as a lifestyle. 我不能喝酒 (wǒ bù néng hē jiǔ) means "I can't drink right now," usually because of medication, driving, or doctor's orders. Mix these up and you accidentally tell people you're on meds when you meant you abstain.

One thing to try this week

Pick a single scene — ordering food, asking for directions, making plans with a friend — and just notice which "can" comes out of a native speaker's mouth, or out of the subtitle line in whatever show you're watching. Don't translate it. Don't grammar-check it. Just notice. When you hear 能 where your brain expected 会, stop and ask why. The answer will almost always be one of the three claims in this post: learned skill, current situation, or permission. After a couple of weeks of this, the decision tree disappears and your gut takes over, which is the whole point. If you want a low-stakes place to try the modals out loud without a person judging you, an AI conversation partner like Conversa lets you run the same sentence three ways and feel which one fits.
