Changed State with '了'

01

Adjectives and Changing Conditions

When used with adjectives or descriptions of conditions (like weather or time), 了 (le˙ㄌㄜlê) implies that the state has developed or changed. Without 了 (le˙ㄌㄜlê), the sentence describes a general state; with 了 (le˙ㄌㄜlê), it describes a current, new state.

• 下雨了。

  xià·yǔ le.ㄒㄧㄚˋ·ㄩˇ ˙ㄌㄜ.shia4·yü3 lê.

  It is raining (now). / It has started to rain.

• 我饿了。

  wǒ è le.ㄨㄛˇ ㄜˋ ˙ㄌㄜ.wo3 o4 lê.

  I am hungry (now).

• 太晚了。

  tài wǎn le.ㄊㄞˋ ㄨㄢˇ ˙ㄌㄜ.t'ai4 wan3 lê.

  It is too late (now).

In the first example, 下雨 (xià·yǔㄒㄧㄚˋ·ㄩˇshia4·yü3) alone refers to the action of raining. Adding 了 (le˙ㄌㄜlê) tells us that it wasn't raining before, but it is raining at this moment.

02

Negative Change: "Not Anymore"

When 了 (le˙ㄌㄜlê) is added to a negative sentence (using 不 (bùㄅㄨˋpu4)), the meaning changes from a simple "no" to "not anymore." This indicates a habit or intention has ceased.

• 我不去了。

  wǒ bù qù le.ㄨㄛˇ ㄅㄨˋ ㄑㄩˋ ˙ㄌㄜ.wo3 pu4 ch'ü4 lê.

  I am not going anymore.

• 他不喝酒了。

  tā bù hē jiǔ le.ㄊㄚ ㄅㄨˋ ㄏㄜ ㄐㄧㄡˇ ˙ㄌㄜ.t'a1 pu4 ho1 chiu3 lê.

  He doesn't drink alcohol anymore.

• 我不要了。

  wǒ bù yào le.ㄨㄛˇ ㄅㄨˋ ㄧㄠˋ ˙ㄌㄜ.wo3 pu4 yao4 lê.

  I don't want it anymore.

03

Using "Already" with 已经

Sentence-final 了 (le˙ㄌㄜlê) is frequently paired with the word 已经 (yǐ·jīngㄧˇ·ㄐㄧㄥyi3·ching1) - already. While 已经 (yǐ·jīngㄧˇ·ㄐㄧㄥyi3·ching1) adds emphasis, 了 (le˙ㄌㄜlê) is grammatically required at the end of the sentence to complete the structure of "already."

• 已经五点了。

  yǐ·jīng wǔ diǎn le.ㄧˇ·ㄐㄧㄥ ㄨˇ ㄉㄧㄢˇ ˙ㄌㄜ.yi3·ching1 wu3 tien3 lê.

  It is already five o'clock.

• 他们已经走了。

  tā·men yǐ·jīng zǒu le.ㄊㄚ·˙ㄇㄣ ㄧˇ·ㄐㄧㄥ ㄗㄡˇ ˙ㄌㄜ.t'a1·mên yi3·ching1 tsou3 lê.

  They have already left.

04

Verbs and New Situations

When placed after a verb phrase at the end of a sentence, 了 (le˙ㄌㄜlê) can indicate that an action has started or a new realization has occurred.

• 我懂了。

  wǒ dǒng le.ㄨㄛˇ ㄉㄨㄥˇ ˙ㄌㄜ.wo3 tung3 lê.

  I understand (now).

• 你知道了。

  nǐ zhī·dào le.ㄋㄧˇ ㄓ·ㄉㄠˋ ˙ㄌㄜ.ni3 chih1·tao4 lê.

  You know (now).

05

Position Matters

It is important to distinguish the "Change of State" 了 (le˙ㄌㄜlê) from the "Completed Action" 了 (le˙ㄌㄜlê).

• Sentence-Final: 了 (le˙ㄌㄜlê) at the end of the sentence focuses on the new situation or current state.
• Verb-Suffix: 了 (le˙ㄌㄜlê) directly after the verb (and before the object) focuses on the completion of the specific action.

• 我吃饭了。

  wǒ chī fàn le.ㄨㄛˇ ㄔ ㄈㄢˋ ˙ㄌㄜ.wo3 ch'ih1 fan4 lê.

  I have eaten. / I am eating now. (Change of state: I wasn't eating/full before, now I am).

• 我吃了饭。

  wǒ chī le fàn.ㄨㄛˇ ㄔ ˙ㄌㄜ ㄈㄢˋ.wo3 ch'ih1 lê fan4.

  I ate a meal. (Completed action: The act of eating is finished).
