Expressing Possibility

When used with activities that are consciously learned or studied, 能 (néng) generally means that circumstances do not allow execution of the action. In other words, it's not possible.

Structure

Examples

开车一个小时能到家吗？
Kāichē yī gè xiǎoshí néng dào jiā ma?
Is it possible to drive home in one hour?
他们明天能早点来吗？
Tāmen míngtiān néng zǎo diǎn lái ma?

Other Usages

From these examples we can see such circumstances might be pertaining to getting someone's consent or reliant on the speaker's health. If the speaker wishes to express that they are able to execute an action requiring a consciously studied skill, 会 (huì) can be used instead.

Because 能 (néng) can express possibility, it is often used to form polite questions, something like "would it be possible" in English:

Examples

我能问你一个问题吗？
Wǒ néng wèn nǐ yī gè wèntí ma?
Could I ask you a question?
我能坐在这里吗？
Wǒ néng zuò zài zhèlǐ ma?

It's not allowed, or not possible for other reasons.
