{{Grammar Box}} This is one of the trickiest comparisons, as 会 (huì), 能 (néng), and 可以 (kěyǐ) are often translated as "can." Sometimes they are explained as: 会 means "know how to," 能 means "to be able to," and 可以 means "to have permission to." Actually, they overlap somewhat. == Basic Meanings == The words 会 (huì), 能 (néng), and 可以 (kěyǐ) actually overlap a little in meaning. The first step is to understand their basic meanings, though: # 会 (huì) can mean "know how to" and can express an action that you had to learn or be trained in to do. # 能 (néng) means "to be able to" and expresses having a certain ability or having obtained a certain minimum requirement. # 可以 (kěyǐ) means "may" or "to be allowed to" and expresses having another person's permission. As for overlap, this graphic helps explain nicely: [[File:Hui-neng-keyi-venn-diagram.png]] The regions marked by letters are explained in the sections below: * A: ability in the sense of “know how to” (会 (huì) is more common than 能 (néng)) * B: permission/request (use 能 (néng) or 可以 (kěyǐ)) * C: possibility (use 能 (néng) or 可以 (kěyǐ)) * D: permission not granted (use 不可以 (bù kěyǐ)) * E: impossibility (use 不能 (bù néng)) == Expressing Ability == Both 会 and 能 can be used to express ability in something. === Structure ===

== Expressing Permission == 可以 is used to ask for or give permission. However, 能 can also be used to replace 可以 interchangeably. '''Note:''' When a question is asked using 能/可以 it can be answered with 不能/不可以, meaning no, and only 可以 meaning yes. Chinese don't really answer with just 能。 === Structure ===

== Using Adverbs to Add Emphasis == By placing 很 (hěn) before 会, it adds emphasis to the level of ability and skill on the action presented. 很会 is commonly used to mean 'to be good at" and expresses being very skillful at something, or doing something very well. It can be translated as "really can," as in "you ''really'' can speak Chinese!," in other words, "you are good at speaking Chinese." When 很 is placed in front of 能, the meaning takes on a amazed/surprised tone on the action. Although more rarely used, it emphasis quantity and amount. 很能 is most commonly used with 吃(chī) to eat, and 睡 (shuì) to sleep. It's like the English equivalent of saying you "can really" do something. For example saying that someone "''can really'' sleep" means that they can sleep a lot. '''Note:''' 很可以 is not a phrase and therefore can not be used with 会 to add emphasis. Other adverbs like 真 (zhēn), 太 (tài), 这么 (zhème) etc. can also be used. === Structure ===
很 + 会／能 + Verb
=== Examples ===
*这个 女生 很 会 打扮 。Zhège nǚshēng hěn huì dǎban.This girl knows how to dress up really well. *我 妈妈 很 会 做饭 。My mom cooks very well.Wǒ māma hěn huì zuòfàn.My mother really knows how to cook. *他 很 会 说话 。The subject has good speaking skills.Tā hěn huì shuōhuà.He's a smooth talker. *他 很能 说 。Tā hěn néng shuō.He's quite a talker.
Note that 很可以说 is wrong and it doesn't mean anything. Examples used with other adverbs:
*他 太 能 睡 了 。The subject can sleep a lot, for many hours.Tā tài néng shuì le.He can really sleep. *没想到 你 这么能 吃苦 。Méixiǎngdào nǐ zhème néng chīkǔ.I didn't expect you to be a person who can handle so many burdens. *你 真能 吃 !The subject can eat a lot.Nǐ zhēn néng chī!Wow, you really can eat! *中国 人 真会 吃 !The subject has great knowledge about food and its culture, a true connoisseur.Zhōngguó rén zhēn huì chī!Chinese people really can eat. Note that 很可以吃 is wrong and it doesn't mean anything.
