Verbs can take potential complements that indicate whether or not the action is actually possible. They are useful in Chinese to say if an action can take place.

Affirmative Pattern

Structurally, potential complements are closely related to both result complements and direction complements, so it helps to be familiar with those first. The most important and commonly used potential complements are derived from other complements such as the following:

Verb + 见 e.g. 看见, 听见 (result complements)
Verb + 懂 e.g. 看懂, 听懂 (result complements)
Verb + 完 e.g. 吃完, 做完, 用完, 花完 (result complements)
Verb + Adj. e.g. 看清楚, 听明白, 洗干净 (result complements)
Verb + 到 e.g. 找到, 买到, 收到 (result complements)
Verb + Direction e.g. 上来, 下去, 进去, 起来, 走过去, 爬上去 (direction complements)

Potential complements can be positive or negative. What this means is fairly intuitive - potential complements can be used to express that something can happen or that it can't.
