會 vs 能 vs 可以: Ability & Permission
Three words. One English translation: 'can.' Getting them wrong doesn't just sound unnatural — it changes the meaning of your sentence. Here is how Taiwanese Mandarin uses each one and why TOCFL tests the difference so aggressively.
The Three Words at a Glance
Something you learned how to do. A skill acquired through study or practice. Also: future events.
我會說中文。
I can speak Chinese. (I learned it.)
If you say 我能說中文, it sounds like you're physically capable of producing speech — not that you learned the language.
Something that is physically or circumstantially possible. The conditions allow it.
我今天不能去。
I can't go today. (Circumstances prevent it.)
If you say 我不會去, it means 'I won't go' (future intention), not 'I can't go' (blocked by circumstances).
Something that is permitted or acceptable. Someone allows it, or it's socially acceptable.
我可以進來嗎？
May I come in? (Do I have permission?)
可以 is the default for asking permission. 會 is wrong here — you're not asking if you have the skill to enter.
Head-to-Head Comparison
Speaking a language
會: 我會說日文。 (I can speak Japanese — I learned it.)
能: 我能說日文。 (I am physically capable of speaking Japanese — odd unless you lost your voice.)
可以: 我可以說日文。 (I'm allowed to speak Japanese — permission in this context.)
Best choice: 會 — language ability is a learned skill.
Going to an event
會: 我會去。 (I will go — intention/plan.)
能: 我能去。 (I can go — circumstances allow it, I'm free.)
可以: 我可以去。 (I can go — I have permission, or it works for me.)
Best choice: 能 or 可以 depending on whether the barrier is circumstances or permission.
Driving
會: 我會開車。 (I know how to drive — I have the skill.)
能: 今天我不能開車。 (I can't drive today — maybe I drank, or the car is broken.)
可以: 你可以開我的車。 (You can drive my car — I give you permission.)
Best choice: 會 for the skill itself, 能 for circumstantial blockers, 可以 for permission.
Taiwanese Mandarin Specifics
Taiwanese Mandarin uses 會 for learned abilities more broadly than Mainland Mandarin. In Taiwan, 你會說英文嗎？ is the default way to ask if someone speaks English. Mainland speakers may also use 能說英文嗎？ in some contexts, but in Taiwan that phrasing sounds slightly unnatural — it shifts the question from 'do you have the skill' to 'are you physically capable of producing English speech.' When in doubt in Taiwan, default to 會 for skills and learned abilities.
Negation: The Same Three, Reversed
我不會游泳。
I can't swim. (I never learned.)
我不能游泳。
I can't swim. (Doctor said no / pool is closed.)
這裡不可以游泳。
You can't swim here. (Not allowed — rules prohibit it.)
TOCFL Note
TOCFL Band A explicitly tests the distinction between 會, 能, and 可以 — typically through multiple-choice questions where three options are grammatically possible but only one is contextually correct. Band B adds the interaction with 把 sentences (你不能把車停在這裡).
Common Mistakes
Using 會 for permission
我會去廁所嗎？
我可以去廁所嗎？
會 is never used for permission. 會 + verb = learned skill or future intention. 可以 + verb = permission.
Using 可以 for learned skills
我可以說中文。
我會說中文。
可以說中文 sounds like you have permission to speak Chinese — odd in most contexts. Use 會 for skills you've acquired.
