- Also known as: 可能补语 (kěnéngbǔyǔ) and complements of potentiality .
Potential complements are a type of complement used to express the possibility of achieving an expected result in Mandarin.
Potential forms most commonly occur in negative statements. Affirmative statements using the potential form are somewhat uncommon, and, when they do occur, are usually answers to questions (or 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 Complement | Directional Complement | Aff. Potential Complement | Neg. Potential Complement |
|---|---|---|---|
| 做 完 | 做 得 完 | 做 不 完 | |
| 听 懂 | 听 得 懂 | 听 不 懂 | |
| 起 来 | 起 得 来 | 起 不 来 | |
| 爬上来 | 爬 得 上来 | 爬 不 上来 |

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 change 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).
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.
Contrasting Degree 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 scenarios put these examples in a context and distinguish them as potential and degree complements.
Potential Complements
A:他跑得快，跑不快？
B:他跑得快。
A:她能说得清楚吗？
B:他说不清楚。
Degree Complements
A: 我的朋友跑得很快，他呢？
B:他跑得快。
A:她说得清楚还是说得不清？
B:她说得清楚。
Degree complements commonly are directly preceded by an adverb (他输得很清楚) distinguishing them from potential complements which are never directly preceded by an adverb.
Particles and Auxiliary Verbs with Potential Form
- Aspect particles 了, 着, and 过 never occur after a verb with a potential complement. subject predicate structure.
- 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.
