不……了 (not anymore)

• Pinyin: le
• Formation: Subject + 不 + Verb / Adj. + 了
• Hanzi breakdown: 了 = a pictographic character originally depicting a child with arms — later abstracted as a grammatical particle

Meaning

The pattern 不……了 (bù...le) is used to express that something is 'not anymore' or that a situation has changed from what it was before. It indicates a shift in state or a decision to stop doing something.

This pattern combines the negation word 不 with the sentence-final particle 了 to signal a change of state. It is different from simple negation with 不, which states a general fact. By adding 了, the speaker emphasizes that the situation is different now compared to before. For example, 我不喝酒 means 'I don't drink alcohol' (as a general habit), while 我不喝酒了 means 'I don't drink alcohol anymore' (implying a change). This pattern is extremely common in everyday Mandarin and is one of the most important uses of 了 for beginners to master.

Examples

1. 他不抽烟了。 He doesn't smoke anymore.
2. 天气暖和了，我不穿外套了。 The weather is warm now, I'm not wearing a jacket anymore.
3. 我不吃辣的了。 I don't eat spicy food anymore.
