已经 + Duration + 没 + Verb + 了 (duration of inaction)

• Pinyin: méi
• Formation: Subj. + (已经 +) Duration + 没 + Verb + 了
• Hanzi breakdown: 没 = 氵(water) + 殳 (weapon) — originally meant 'to submerge'

Meaning

This pattern expresses how long it has been since someone last did something. The structure uses 没 to negate the verb, combined with a duration phrase, to indicate a period of inaction up to the present moment.

This pattern is essential for expressing that something hasn't happened for a certain period of time. 已经 (already) is often included for emphasis but is optional. The sentence-final 了 indicates a change of state — it signals that the duration of inaction has reached the stated amount and continues to the present. Note that 没 is used instead of 不, because 没 negates completed or experienced actions. Common errors include omitting the final 了 or using 不 instead of 没. This pattern naturally pairs with follow-up clauses expressing feelings or consequences.

Examples

1. 我已经三天没吃肉了。 I haven't eaten meat for three days already.
2. 她两个星期没给我打电话了。 She hasn't called me for two weeks.
3. 他们已经半年没见面了。 They haven't seen each other for half a year already.

Origin & History

This pattern combines negation with duration to express elapsed inaction. 没 originally depicted water submerging something, evolving into a general negation marker for past events. The sentence-final 了 indicates the situation has reached the current moment.
