Verb-Complement Separable Compounds
动补式离合词：打开、看见、离开、完成
Use verb-complement compounds and understand how potential complements (得/不) split them apart
Verb-complement compounds consist of a verb plus a result or direction complement. When expressing ability or inability, insert 得 (can) or 不 (cannot) between the verb and complement to form the potential complement pattern.
Unlike verb-object separable verbs (GP-05), these split using the potential complement pattern V + 得/不 + C. For example, 打开 splits into 打得开 (can open) or 打不开 (cannot open).

Understanding 动补式离合词：打开、看见、离开、完成
In the previous lesson, you learned about verb-object separable verbs where 了 and 过 insert between verb and object. Now you meet a different type: verb-complement compounds (动补式离合词). Words like 打开 (open), 看见 (see), 离开 (leave), and 完成 (complete) consist of a verb plus a result complement. The key operation with these is the potential complement: you insert 得 (can) or 不 (cannot) between the two parts to express whether the action can achieve its result. 打不开 means "cannot open," 看不见 means "cannot see," 离不开 means "cannot leave / cannot do without." This is one of the most powerful and frequently used patterns in spoken Chinese — it lets you express possibility and impossibility in a compact, natural way. Mastering it will make your Chinese sound significantly more fluent.
Key Points
- 打开 (dǎkāi, open) → 打得开 (can open) / 打不开 (cannot open).
- 看见 (kànjiàn, see) → 看得见 (can see) / 看不见 (cannot see).
- 离开 (líkāi, leave) → 离得开 (can be apart from) / 离不开 (cannot be apart from).
- 完成 (wánchéng, complete) → 完得成 (can complete) / 完不成 (cannot complete).
- The positive potential form (V + 得 + C) is less common in daily speech than the negative (V + 不 + C).
- These compounds can also take 了 normally: 打开了 (opened), 看见了 (saw).
- The potential complement is about real-world possibility, not permission (use 可以 for permission).
The phrase 离不开 (líbukāi) is commonly used to express emotional dependence: 我离不开你 means "I can't live without you" or "I can't be apart from you." It appears frequently in Chinese pop songs and dramas, making it a culturally rich expression that goes beyond its literal meaning.
Key Vocabulary
Example Sentences

Common Mistakes
When the issue is about achieving a result (can't manage to open it), use the potential complement 打不开, not 不能打开. 不能 is for permission or external circumstances.
The potential complement form (V不C) does not take 了. The object goes directly after the complement.
The 不 inserts between the verb 离 and the complement 开, not after the whole word. The correct split is 离 + 不 + 开.
Practice Exercises
Tips & Tricks
The pattern V + 不 + C is incredibly common in spoken Chinese. Start noticing it in TV shows and conversations.
Think of the verb and complement as two pieces of a puzzle — 得 or 不 slides in between them like a connector.
The negative form (V不C) is used far more often than the positive (V得C). When you can do something, you usually just state the result directly.
Practice by thinking about daily frustrations: can't open a jar? 打不开。Can't see the screen? 看不见。This makes the pattern stick.
Homework
For each verb-complement compound (打开, 看见, 离开, 完成), write two sentences: one using the negative potential (V不C) and one using the positive potential (V得C). Add context to make each sentence feel like a real situation.
