The Double 了 in Mandarin: 我学了三年中文了

By Michael McGettrick and Wee Khang LinUpdated 12 October 2026

(wǒ xué le sān nián Zhōngwén le) has two (le), and each does its own job. The one after the verb gives the amount: three years of study. The one at the end brings it up to now: and I still am. It is the Mandarin for "I've been learning Chinese for three years". The two 了 page introduced both.

Quick check

Three quick questions on what you have just read. The full practice is further down.

HanziPinyinEnglish
。Wǒ xué le sān nián Zhōngwén le.I've been learning Chinese for three years
。Tā shuì le bā ge xiǎoshí le.He's been asleep for eight hours
。Wǒ děng le bàn ge xiǎoshí le.I've been waiting for half an hour
。Wǒ chī le sān wǎn fàn le.I've had three bowls already

Read it in two layers: (xué le sān nián Zhōngwén), three years of Chinese done; then the final (le), and counting.

What the final 了 (le) adds

了 le after the verb (the amount done)了 le at the end (up to now)What do the colours mean?

Take the final (le) off and the stretch is reported as finished. Nothing else changes:

HanziPinyinEnglish
。Tā shuì le bā ge xiǎoshí.He slept for eight hours
。Tā shuì le bā ge xiǎoshí le.He's been asleep for eight hours
。Wǒ děng le bàn ge xiǎoshí.I waited for half an hour
。Wǒ děng le bàn ge xiǎoshí le.I've been waiting for half an hour
。Tā zhù le liǎng nián.She lived there for two years
。Tā zhù le liǎng nián le.She's lived there for two years

  • 他睡了八个小时 tā shuì le bā ge xiǎoshí: eight hours, and over

  • 他睡了八个小时了 tā shuì le bā ge xiǎoshí le: eight hours so far, still asleep

Timeline from past to now, with now marked.

So if you are still doing it as you speak, the final (le) is what says so. English "have been doing for" is nearly always this pattern.

Not just time: the count so far

了 le after the verb (the amount done)了 le at the end (up to now)What do the colours mean?

Any amount works, not only a length of time. The final (le) says "that's the count so far", often with a hint that it is a lot:

HanziPinyinEnglish
。Wǒ chī le sān wǎn fàn le.I've had three bowls already
。Wǒ hē le liǎng bēi kāfēi le.I've had two coffees already
。Tā dǎ le sān cì diànhuà le.He's phoned three times now

Without the final (le), each is a plain report: (wǒ chī le sān wǎn fàn), I ate three bowls.

Where the object goes

了 le after the verb (the amount done)了 le at the end (up to now)What do the colours mean?

In careful Mandarin the amount goes between the verb and the object. If that feels cramped, say the verb twice, or put the object first:

HanziPinyinNote
。Wǒ xué le sān nián Zhōngwén le.amount before object
。Wǒ xué Zhōngwén xué le sān nián le.verb said twice
。Zhōngwén wǒ xué le sān nián le.object put first

All three mean "I've been learning Chinese for three years". The same rules hold for one (le): see duration complements. Two orders you will hear in speech:

  • (wǒ xué le Zhōngwén sān nián le), time after the object: casual, and textbooks mark it wrong. Do not write it.
  • 。 (Wǒ xué Zhōngwén sān nián le.) - I've been learning Chinese for three years. No after the verb: the time counts from when you started, like the time-since pattern below.

Time since: 他来了三天了 (tā lái le sān tiān le)

了 le after the verb (the amount done)了 le at the end (up to now)What do the colours mean?

Some verbs are over in a moment: come, arrive, get married. With them the time counts from when it happened, not how long it took:

HanziPinyinEnglish
。Tā lái le sān tiān le.He's been here three days
。Tā lái Zhōngguó sān nián le.He came to China three years ago
。Wǒmen jiéhūn shí nián le.We've been married ten years

Here the time can follow the object, and the after the verb can go: (lái Zhōngguó sān nián le). The final (le) stays, because the count runs up to now.

Mistakes English speakers make

WrongRightWhy
。。for "and I still am": the final (le) says so
。。for "he's still asleep": add the final (le)
。。careful Mandarin puts the amount first

What to do next

  1. Do the drill below.
  2. Say how long you have been learning Chinese and living where you live: … (wǒ xué le … Zhōngwén le).
  3. Then read duration complements for "how long" with one (le) or none.

Frequently asked questions

What does the double (le) mean in Mandarin?
Verb + + amount + (object) + says the action has reached that amount and is still going. (wǒ xué le sān nián Zhōngwén le) is 'I've been learning Chinese for three years'. It is how Mandarin says English 'have been doing for'.
What happens if I drop the final (le)?
The stretch is reported as finished. (wǒ xué le sān nián Zhōngwén) is 'I studied Chinese for three years', and the natural reading is that you have stopped. To say you still are, keep both: (wǒ xué le sān nián Zhōngwén le).
Where does the time go when there is an object?
Before the object: (wǒ xué le sān nián Zhōngwén le). Or say the verb twice: (wǒ xué Zhōngwén xué le sān nián le). (wǒ xué le Zhōngwén sān nián le), with the time after the object, is the order textbooks mark wrong. You will hear it in casual speech, but put the amount first.
Does the double (le) only work with time?
No. Any amount works: (wǒ chī le sān wǎn fàn le), I've had three bowls already; (tā dǎ le sān cì diànhuà le), he's phoned three times now. The final says this is the count so far.
Why does not mean he came for three days?
Because (lái), come, is over in a moment, so the time counts from when it happened: (tā lái le sān tiān le), he's been here three days, he arrived three days ago. (jiéhūn), get married, works the same way: (wǒmen jiéhūn shí nián le), we've been married ten years.
