+## Verb Complement: 了 (le) vs. 完 (wán)
+
+Both attach to the end of a verb, but they answer different questions.
+
+---
+
+### 了 (le) — "Did it happen?"
+了 marks that an action **occurred**. It doesn't say anything about whether you finished it.
+
+我吃了饭
+Wǒ chīle fàn
+I ate (some) food. / I had a meal.
+
+我看了那本书
+Wǒ kànle nà běn shū
+I read that book. (Started it, read some of it — doesn't mean you finished.)
+
+我写了作业
+Wǒ xiěle zuòyè
+I did (some of) my homework.
+
+---
+
+### 完 (wán) — "Did you finish ALL of it?"
+完 is a **result complement** meaning "to completion." It implies nothing was left undone — you saw it through to the end.
+
+我吃完了饭
+Wǒ chī wánle fàn
+I finished eating. (The plate is clean.)
+
+我看完了那本书
+Wǒ kàn wánle nà běn shū
+I finished reading that book. (Cover to cover.)
+
+我写完了作业
+Wǒ xiě wánle zuòyè
+I finished all my homework.

+### Side-by-Side Contrast
+
+| Sentence | Meaning |
+|---|---|
+| 我读了这本书 / Wǒ dúle zhè běn shū | I read this book. (Maybe just part of it.) |
+| 我读完了这本书 / Wǒ dú wánle zhè běn shū | I finished reading this book. (All of it.) |
+| 我吃了 / Wǒ chīle | I ate. (The action happened.) |
+| 我吃完了 / Wǒ chī wánle | I'm done eating. (Nothing left.) |
+
+**Rule of Thumb:**
+- 了 → the action took place
+- 完 → the action reached its natural end point, nothing left over
