Also known as: 可能补语 (kěnéngbǔyǔ)  and complement of potentiality.

Potential complements are a type of complement used to express the possibility (potential) of achieving an expected result.

Potential forms most commonly occur in negative statements. Affirmative statements using the potential form, when they do occur, usually give answers to questions or serve as rebuttals.

Formation of Potential Complements

For affirmative potential complements, 得 is placed between the action verb and the complement. For negative potential complements, 不 is placed between the action verb and complement. The structure of the potential form is:

V + 得/不 + complement

Putting 得 or 不 between an action verb and a result complement or direction complement changes them to potential complements.

Resultative, Directional and Potential Complements

Objects occurring at the end of a sentence with a potential complement

When to Use Potential Complements

The potential complement is roughly equivalent to saying something is able to be done in English. It is used when you want to express ability to achieve a result (as noted above, a result complement can be changed into a potential complement be inserting 得 or 不 between the verb and the complement) or ability to perform an action to a certain degree, similar to degree complements. Degree complements and potential complements often appear the same but are distinguished by the different contexts they appear in (see Contrasting Degree and Potential Complements section below).

Special Potential Complements

In addition to common result complements that can be turned into potential complements and adjectives that form either degree or potential complements there are several complements that have unique meanings as potential complements.

Special Potential Complements
Complement Example Complement Phrase Example Sentence Explanation
走不动 我们 累 死了 ,走 不 动 了 。 (We are so tired, we can't (don't have the strength to) walk any more.) The potential complement 动 indicates whether a person has the strength to be able to undertake an action whether that be moving them self (walking further) or an object.
抬得动 她 力气 很 大 ,她 抬 得 动 这 张 沙发 。(She is very strong, she can lift this sofa.)
坐得下 这 间 大 房子 ,坐 得 下 十 个 人 。(This big room can seat ten people) The potential complement 下 expresses the ability to fit in or on a given location.
放不下 那个 包 ,放 不 下 这些 西瓜 。(That bag cannot fit these watermelons)
受不了 今天 天气 太 热 了 ,我受不了 了 。(Today it is too hot, I am unable to bear it) The potential complement 了 expresses the ability do the verb. Note: 了 can also serve as an adjective complement which means ability to reach a degree
来得了 今天开会我来得了(I am able to come to today's meeting)

Use of Potential Complement or Auxiliary Verbs 可以 and 能

In most cases simple potential complement phrase will have the same meaning as a verb phrase using auxiliary verbs 能 or 可以. For example, 他爬得上来 has the same meaning as 他能爬上来 and 他可以爬上来. Likewise 我能做完, 我可以做完 and 我做得完 all have the same meaning.

Potential Complements in Questions

You can form questions with sentences containing potential complements just as you would with any other sentence:

Some examples:

  • 你 做得 完 吗 ?Did you finish it?
  • 你 受不 了 吗 ?Weren't you able to handle it?
  • 谁 吃得 完 整只 鸡 ?Who ate the entire chicken?
  • 你 觉得 你 考得 上 什么 大学?What college do you think you tested into?
  • 那间 房子 坐得 下 坐不 下 十个人?Will that apartment fit ten people in it?
  • 明天的音乐会 你 来得 了 来不 了?Are you able to come to tomorrow's concert?

Comparing Degree Complements and Potential Complements

Some sentences that contain adjective complements may be indistinguishable as degree or potential complements when they are taken out of context. For example 跑得快 or 说得清楚 could serve as either potential or degree complements. The following table explains different meanings that one complement phrase could have as either a degree or potential.

Examples of complement phrases that can serve as both degree and potential complements
Example Degree Complement Translation Potential Complement Translation
她说得清楚 "She speaks clearly." "She is able to speak clearly."
他跑得快 "He runs fast." "He is able to run fast."


Degree complements commonly are directly preceded by an adverb (他说得很清楚) distinguishing them from potential complements which are never directly preceded by an adverb.

Particles and Auxiliary Verbs with Potential Complements

  • Aspect particles 了, 着, and 过 never occur after a verb with a potential complement, they may however occur after a potential complement phrase (after the complement).
  • Auxiliary verbs of possibility (可能, 可以, etc.) can be used in an affirmative potential complement statement and do not change the meaning of the sentence. They do not occur in negative potential complement sentences.
