会, 能, 可以: three ways to say can in Chinese

English uses “can” for many jobs. Mandarin splits those jobs.

会 often means a learned ability.

能 often means physical ability or circumstances allow it.

可以 often means permission or that something is acceptable.

我今天不能开车。	wǒ jīn tiān bù néng kāi chē.	I cannot drive today.	Situation prevents it
我可以坐这里吗？	wǒ kě yǐ zuò zhè lǐ ma?	Can I sit here?	Permission

If you translate every “can” as 可以, you will be understood sometimes and sound clumsy often. That is better than silence, but it is not the target.
