Potential complement
- Also known as: 可能补语 (kěnéngbǔyǔ) and complements of potentiality .
Potential complements are 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 |
