V + Complement + 了 (了 with complements)

• Pinyin: le
• Formation: Subj. + Verb + Complement + 了

Meaning

When 了 appears in sentences with resultative or degree complements, it must follow the complete verb-complement unit rather than being inserted between the verb and its complement. The verb and complement form an inseparable unit, and 了 signals that the result has been achieved.

The interaction between 了 and complements is a major source of errors for Chinese learners. In the pattern V + Complement + 了, the complement describes the result or degree of the action, and 了 signals that this result has been achieved or the situation has changed. Crucially, 了 never breaks into the V + Complement structure — saying 做了完 instead of 做完了 is always incorrect. With directional complements like 出来, 进去, and 下去, 了 can sometimes appear in the middle (e.g., 拿了出来), but this is a special case limited to directional complements. For resultative complements like 干净, 清楚, 完, and 好, the rule is absolute: the complement must directly follow the verb, and 了 comes after the entire unit.

Examples

1. 他把衣服洗干净了，挂在阳台上晾着。 He washed the clothes clean and hung them on the balcony to dry.
2. 孩子们跑累了，坐在树下休息。 The kids ran until they were tired and sat under a tree to rest.
3. 我看完了这本小说，想再找一本新的。 I finished reading this novel and want to find a new one.

Don't Say

• 他把作业做了完。(With resultative complements, 了 must follow the entire V + Complement unit — 做完了 is correct, not 做了完) → 他把作业做完了。
• 我吃了饱。(了 cannot be inserted between the verb and its resultative complement — the complement must directly follow the verb: 吃饱了) → 我吃饱了。

Origin & History

The placement of 了 after verb-complement structures reflects the grammaticalization process whereby the resultative complement became fused with the verb. In classical Chinese, result and verb were separate; in modern Chinese, they form a tight unit that 了 seals as completed.
