Grammar Rule in 30 Seconds

To express how long an action lasted, place the duration after the verb and add {了|le} to show the action is completed.

  • Subject + Verb + {了|le} + Duration: {我|wǒ} {看|kàn} {了|le} {三|sān} {个|gè} {小|xiǎo}{时|shí} {书|shū} (I read for 3 hours).
  • If there is an object, repeat the verb: {我|wǒ} {看|kàn} {书|shū} {看|kàn} {了|le} {三|sān} {个|gè} {小|xiǎo}{时|shí}.
  • For negative duration, use {没|méi} + Verb + Duration: {我|wǒ} {没|méi} {看|kàn} {三|sān} {个|gè} {小|xiǎo}{时|shí} {书|shū}.
Subject + Verb + 了 + Duration

Overview

Expressing duration—how long an action lasted—is a fundamental aspect of communication in any language. In Chinese, unlike English which often uses prepositions like "for" (e.g., "I studied for two hours"), the concept of duration is conveyed through specific word order and the crucial aspect particle 了|le. This isn't just about saying "how long"; it's about indicating that a certain block of time was entirely consumed by an action that has since concluded.

Understanding this structure is essential for moving beyond basic sentence formation and accurately describing past experiences, whether you're recounting a trip, describing a long work meeting, or simply discussing how much sleep you got. This grammatical pattern highlights a core principle in Chinese: the emphasis on the completion or result of an action, and how temporal information often follows the main verbal event.

Chinese grammar often prioritizes the action itself, with modifiers like duration or frequency appearing after the verb, almost as an additional piece of information about the action's extent. This S + V + Duration or S + V + O + V + Duration structure allows for a clear, sequential presentation of information: who did what, when it was completed, and for how long. Mastering this rule will significantly enhance your ability to express nuanced temporal relationships in your Chinese conversations and writing, elevating your speech from simple statements to more sophisticated narratives.

How This Grammar Works

At its heart, expressing duration with 了|le involves placing the duration phrase after the verb. The particle 了|le functions here as a perfective aspect marker, signaling that the action described by the verb has been completed, or that a stage of the action has concluded. When combined with a duration phrase, 了|le specifically indicates that the action was carried out for the entire specified period.
It's not just about an action happening in the past; it's about an action occupying a continuous stretch of time and then finishing.
Consider the fundamental structure: Subject + Verb + 了 + Duration. This pattern works seamlessly for verbs that do not take a direct object, or when the object is inherently implied. For instance, 我睡了八个小时|Wǒ shuì le bā gè xiǎoshí (I slept for eight hours).
Here, 睡|shuì (to sleep) is the verb, 了|le marks completion of the sleeping action for that duration, and 八个小时|bā gè xiǎoshí (eight hours) specifies the length. The linguistic principle at play is that the verb and its associated aspect (completion) form a tight unit, followed by the quantifiable information about that completed action.
However, complexity arises when a verb takes a direct object. Chinese grammar generally prefers that duration phrases do not directly separate a verb from its direct object, especially for simple V + O constructions. To resolve this, Chinese employs two primary strategies: verb repetition or the use of 的|de to modify the object with the duration.
Both methods ensure that the verb-object relationship remains clear while accommodating the duration information. This preference for non-interruption between verb and object is a common characteristic of Chinese syntax, often referred to as the 'verb-object construction's integrity'. The chosen strategy depends on factors like the type of verb, the nature of the object, and the desired emphasis.
These strategies ensure clarity and maintain idiomatic flow, preventing the utterance from sounding like a direct translation of English structure.

Formation Pattern

1
Mastering duration expressions requires understanding several distinct patterns, each tailored to specific sentence structures. The choice of pattern hinges on whether the verb is transitive (takes an object) or intransitive (does not take an object), and the type of object involved. Below are the primary formation patterns:
2
1. Basic Structure (Intransitive Verbs / No Object)
3
This is the simplest form, used when the verb doesn't require a direct object, or when the object is understood from context. The duration directly follows 了|le.
4
Pattern: Subject + Verb + 了 (le) + Duration
5
Explanation: The verb and 了|le combine to express a completed action. The duration phrase then quantifies the length of this completed action. This structure emphasizes the duration of the action itself.
6
Examples:
7
他病了三天|Tā bìng le sān tiān (He was sick for three days.)
8
我等了十分钟|Wǒ děng le shí fēnzhōng (I waited for ten minutes.)
9
我昨天工作了九个小时|Wǒ zuótiān gōngzuò le jiǔ gè xiǎoshí (Yesterday I worked for nine hours.)
10
2. Transitive Verbs with Objects - Method 1: Verb Repetition
11
When a verb takes a direct object, and you want to express the duration of that action, the most common and often most natural method is to repeat the verb. This separates the original Verb + Object unit from the Verb + 了 + Duration unit, allowing both the object and the duration to be clearly associated with the action.
12
Pattern: Subject + Verb + Object + Verb + 了 (le) + Duration
13
Explanation: The first Verb + Object pair establishes what was done. The repeated Verb + 了 + Duration then specifies for how long that action occurred. This repetition is crucial to maintain the integrity of the verb-object relationship while allowing the duration to follow the verbal core. It's as if you're saying "I studied Chinese; [I] studied for a year." This is especially common with separable verbs (离合词|líhé cí), where the verb and object form a conceptual unit that can be 'split' for other grammatical elements.
14
Examples:
15
我学中文学了一年|Wǒ xué Zhōngwén xué le yī nián (I studied Chinese for a year.)
16
她看电视看了两个小时|Tā kàn diànshì kàn le liǎng gè xiǎoshí (She watched TV for two hours.)
17
他游泳游了半个小时|Tā yóuyǒng yóu le bàn gè xiǎoshí (He swam for half an hour.) – 游泳|yóuyǒng is a separable verb.
18
3. Transitive Verbs with Objects - Method 2: 的|de Construction
19
An alternative, though often more specific, way to express duration with a transitive verb and object is using 的|de. This structure often implies that the duration modifies the quantity or amount of the object that was affected by the action.
20
Pattern: Subject + Verb + 了 (le) + Duration + 的 (de) + Object
21
Explanation: This pattern treats the duration as an adjective phrase modifying the object. It implies an "amount of X duration's worth of object." For example, 一年的中文|yī nián de Zhōngwén means "a year's worth of Chinese." This structure is generally preferred when the object is somewhat quantifiable or when the focus is on the result of the duration on the object, rather than just the action itself. It can sometimes sound more concise than verb repetition.
22
Examples:
23
我学了一年的中文|Wǒ xué le yī nián de Zhōngwén (I studied a year's worth of Chinese / I studied Chinese for a year.)
24
他写了两个小时的作业|Tā xiě le liǎng gè xiǎoshí de zuòyè (He wrote two hours' worth of homework / He did homework for two hours.)
25
她唱了半个小时的歌|Tā chàng le bàn gè xiǎoshí de gē (She sang half an hour's worth of songs / She sang for half an hour.)
26
4. Transitive Verbs with Objects - Method 3: Pronoun Object
27
When the object of a transitive verb is a pronoun (他|tā, 她|tā, 它|tā, 我|wǒ, 你|nǐ, 我们|wǒmen, etc.), the word order changes. The pronoun object is inserted directly after Verb + 了, and then followed by the duration.
28
Pattern: Subject + Verb + 了 (le) + Pronoun Object + Duration
29
Explanation: This is a notable exception to the general rule of not separating V+O. With pronouns, which are usually short and unstressed, this order is idiomatic and avoids the awkwardness of repeating the verb before a pronoun. It highlights the direct involvement of the person/thing represented by the pronoun in the action for that specified time.
30
Examples:
31
我等了他半个小时|Wǒ děng le tā bàn gè xiǎoshí (I waited for him for half an hour.)
32
她教了我三年中文|Tā jiāo le wǒ sān nián Zhōngwén (She taught me Chinese for three years.)
33
我们找了它一整天|Wǒmen zhǎo le tā yī zhěng tiān (We looked for it for an entire day.)
34
Summary Table of Formation Patterns:
35
| Type of Verb / Object | Pattern | Example | Emphasis / Nuance |
36
| :-------------------------- | :------------------------------------------- | :-------------------------------------------------- | :-------------------------------------------------- |
37
| Intransitive Verb | S + V + 了 + Duration | 我睡了八个小时 (I slept for 8 hours.) | Duration of the action itself. |
38
| Transitive V + O | S + V + O + V + 了 + Duration | 我学中文学了一年 (I studied Chinese for a year.) | Action (V+O) happened; then its duration. Common. |
39
| Transitive V + O | S + V + 了 + Duration + 的 + O | 我学了一年的中文 (I studied a year's worth of Chinese.) | Duration as modifier of the object's quantity/amount. |
40
| Transitive V + Pronoun | S + V + 了 + Pronoun + Duration | 我等了他半个小时 (I waited for him for half an hour.) | Standard for pronoun objects. |

When To Use It

This grammatical structure is employed specifically when you need to express that an action was carried out for a completed, continuous period of time in the past. It answers the question "How long did [action] last?" or 多长时间|duō cháng shíjiān?. The key characteristic here is the completion of the duration; the action is no longer ongoing at the moment of speaking.
  • Describing Past Activities: This is the most common usage. You use it to tell someone how long you did something in the past that has since finished.
  • 我昨晚读了两个小时的书|Wǒ zuówǎn dú le liǎng gè xiǎoshí de shū (Last night I read books for two hours.) - The reading is over.
  • 我们在北京住了五年|Wǒmen zài Běijīng zhù le wǔ nián (We lived in Beijing for five years.) - They no longer live there.
  • Reporting on Events with a Fixed End: When an event or state had a clear beginning and end, and you're specifying its length.
  • 这个会议持续了三个小时|Zhège huìyì chíxù le sān gè xiǎoshí (This meeting lasted for three hours.)
  • 他病了三天|Tā bìng le sān tiān (He was sick for three days.) - His sickness has concluded or gotten better.
  • Emphasis on the Block of Time: Sometimes, the focus isn't just on the action, but on the significant chunk of time it consumed. This pattern highlights that entire duration.
  • 我们讨论了很久|Wǒmen tǎolùn le hěn jiǔ (We discussed for a long time.)
Crucially, do not confuse this with actions that are still ongoing. If an action started in the past and is still happening now, you would typically use the "double 了|le" construction (S + V + 了 + Duration + (O) + 了|le).
| Pattern | Meaning |
| :-------------------------------------- | :---------------------------------------------------------------------- |
| S + V + 了 + Duration | Action completed; lasted for X duration. (我睡了八个小时 - I slept for 8 hours [and stopped].) |
| S + V + 了 + Duration + 了 | Action started X duration ago and is still ongoing. (我睡了八个小时了 - I have been sleeping for 8 hours [and am still sleeping].) |
This distinction is vital for accurately conveying the temporal aspect of your sentences. The single 了|le implies a past, finished block of time, making it suitable for recounting history or completed tasks. The double 了...了 implies a present, ongoing state with a specified duration.

Common Mistakes

Learners frequently encounter pitfalls when applying the duration structure with 了|le. These errors often stem from direct translation from English or from misunderstanding the nuances of Chinese syntax. Identifying and understanding these common mistakes will help you avoid them and achieve native-like fluency.
1. The "English Order" Trap: Placing Duration Before the Verb
This is perhaps the most common error, as English places temporal adverbs (including duration) before the verb or at the very end of the sentence without verb repetition. Chinese, however, requires duration to follow the verb.
  • ❌ Wrong: 我三个小时看电视|Wǒ sān gè xiǎoshí kàn diànshì (Direct translation: I three hours watch TV.)
  • ✅ Right (Verb Repetition): 我看电视看了三个小时|Wǒ kàn diànshì kàn le sān gè xiǎoshí
  • ✅ Right (的|de construction): 我看了三个小时的电视|Wǒ kàn le sān gè xiǎoshí de diànshì
  • Why it's wrong: In Chinese, pre-verbal time expressions typically indicate when an action occurs (a time point), not for how long it occurs (duration). Placing duration before the verb changes its meaning or makes it ungrammatical.
2. Omitting 了|le
Sometimes learners forget to include 了|le after the verb when expressing duration, especially if they are focused on simply conveying the time.
  • ❌ Wrong: 我睡觉八个小时|Wǒ shuìjiào bā gè xiǎoshí (I sleep eight hours – sounds like a general fact or future intent)
  • ✅ Right: 我睡了八个小时|Wǒ shuì le bā gè xiǎoshí
  • Why it's wrong: Without 了|le, the sentence loses its aspect marker indicating completion. It might be interpreted as a habitual action, a future action, or simply sound incomplete. 了|le is crucial for marking the duration as a completed block of time in the past.
3. Incorrect Object Placement with Transitive Verbs
Failing to use verb repetition or the 的|de construction when a transitive verb has an object is a major source of error.
  • ❌ Wrong: 我学了一年中文|Wǒ xué le yī nián Zhōngwén (This separates V+O with duration, which is usually awkward unless 中文 is very general or used colloquially, but not standard.)
  • ✅ Right (Verb Repetition): 我学中文学了一年|Wǒ xué Zhōngwén xué le yī nián
  • ✅ Right (的|de construction): 我学了一年的中文|Wǒ xué le yī nián de Zhōngwén
  • Why it's wrong: Chinese verbs and their direct objects form a close semantic unit. Inserting duration directly between them (e.g., V + Duration + O) generally disrupts this flow and is considered ungrammatical in most contexts. The repetition or 的|de structure allows for both the object and the duration to be expressed naturally.
4. Misplacing Pronoun Objects
While the rule for noun objects is verb repetition or 的|de, pronoun objects follow a different pattern, which can be confusing.
  • ❌ Wrong: 我等他等了半个小时|Wǒ děng tā děng le bàn gè xiǎoshí (While technically understandable, it's not the most idiomatic for pronouns.)
  • ❌ Wrong: 我等了半个小时的他|Wǒ děng le bàn gè xiǎoshí de tā (Incorrect use of 的|de with a pronoun for duration.)
  • ✅ Right: 我等了他半个小时|Wǒ děng le tā bàn gè xiǎoshí
  • Why it's wrong: Pronouns are typically short and highly integrated. The V + 了 + Pronoun + Duration structure is the established idiomatic form, demonstrating how grammatical rules can adapt based on word class.
5. Confusing with the "Double 了...了" Construction
Using the single 了|le duration pattern when the action is still ongoing is a frequent mistake.
  • ❌ Wrong: You've been working for three hours and are still working, but you say 我工作了三个小时|Wǒ gōngzuò le sān gè xiǎoshí.
  • ✅ Right: 我工作了三个小时了|Wǒ gōngzuò le sān gè xiǎoshí le
  • Why it's wrong: The single 了|le signifies a completed block of time. If the action is still continuing, the second 了|le is indispensable to indicate the ongoing nature of the state or action relative to the present moment. This mistake fundamentally alters the meaning of your statement.

Real Conversations

Understanding the theory is one thing; seeing these patterns in authentic communication is another. Here’s how native speakers naturally use duration expressions with 了|le in everyday contexts, reflecting both casual chat and more formal reporting.

S

Scenario 1

Describing a Recent Activity (Intransitive Verb)
A

A

你昨晚几点睡的？看起来很累。|Nǐ zuówǎn jǐ diǎn shuì de? Kàn qǐlái hěn lèi.

(What time did you sleep last night? You look very tired.)

B

B

唉，我工作到很晚，只睡了五个小时。|Ài, wǒ gōngzuò dào hěn wǎn, zhǐ shuì le wǔ gè xiǎoshí.

(Ugh, I worked very late, only slept for five hours.)

- Observation: 睡了五个小时|shuì le wǔ gè xiǎoshí clearly indicates the completed duration of sleep.

S

Scenario 2

Discussing a Skill or Experience (Verb Repetition)
A

A

你学了多久的汉语了？发音真棒！|Nǐ xué le duōjiǔ de Hànyǔ le? Fāyīn zhēn bàng!

(How long have you been studying Chinese? Your pronunciation is great!)

B

B

谢谢！我学汉语学了三年了。|Xièxie! Wǒ xué Hànyǔ xué le sān nián le.

(Thanks! I've been studying Chinese for three years. [Implies still studying, but here the 'le' after duration can be omitted if the focus is purely on completed years of study.])

- Observation: Even if the action continues, 我学汉语学了三年|wǒ xué Hànyǔ xué le sān nián can be used to state the completed block of time, if the 'ongoing' aspect is covered by the final 了|le of the entire sentence. Here, the verb 学|xué is repeated to accommodate the object 汉语|Hànyǔ and the duration 三年|sān nián.

S

Scenario 3

Talking about Waiting for Someone (Pronoun Object)
A

A

小王怎么还没来？不是说八点到吗？|Xiǎo Wáng zěnme hái méi lái? Bù shì shuō bā diǎn dào ma?

(Why isn't Xiao Wang here yet? Didn't he say he'd arrive at eight?)

B

B

别提了，我等了他快一个小时了！|Bié tí le, wǒ děng le tā kuài yī gè xiǎoshí le!

(Don't even mention it, I've waited for him for almost an hour already!)

- Observation: 等了他快一个小时|děng le tā kuài yī gè xiǎoshí shows the standard structure for a pronoun object. The final 了|le in the sentence indicates the waiting is still ongoing.

S

Scenario 4

Describing a Task (Using 的|de Construction)
A

A

你把那些报告都看完了吗？|Nǐ bǎ nàxiē bàogào dōu kàn wán le ma?

(Have you finished reading all those reports?)

B

B

还没呢，我只看了半个小时的报告。太多了！|Hái méi ne, wǒ zhǐ kàn le bàn gè xiǎoshí de bàogào. Tài duō le!

(Not yet, I only read half an hour's worth of reports. Too many!)

- Observation: 看了半个小时的报告|kàn le bàn gè xiǎoshí de bàogào indicates that the duration (half an hour) quantifies the amount of 报告|bàogào (reports) that were read.

These examples demonstrate the flexibility and necessity of using the correct pattern based on the verb's transitivity and the object's type, reflecting the practical application of this rule in spoken Chinese.

Quick FAQ

Here are answers to some frequently asked questions, addressing common points of confusion and providing further clarification on duration expressions in Chinese.
Q1: Do I always need verb repetition (e.g., S + V + O + V + 了 + Duration) for transitive verbs?
A1: While verb repetition is often the most natural and grammatically robust option, especially for common V+O verbs like 看电视|kàn diànshì (watch TV) or 学汉语|xué Hànyǔ (study Chinese), the S + V + 了 + Duration + 的 + O construction is a valid alternative. The choice can sometimes depend on nuance or personal preference. The 的|de construction often subtly shifts emphasis towards the quantity of the object affected by the duration.
For instance, 我看了三个小时的电影|Wǒ kàn le sān gè xiǎoshí de diànyǐng (I watched three hours' worth of movie) might slightly emphasize the movie itself as a 'three-hour-long' entity, whereas 我看电影看了三个小时|Wǒ kàn diànyǐng kàn le sān gè xiǎoshí might emphasize the act of watching. Both are correct, but verb repetition is generally considered a safer bet for general usage and is very common.
Q2: Can I drop the 了|le after the verb?
A2: Generally, no. The 了|le particle is crucial for marking the perfective aspect, signaling that the action for that duration has been completed. Omitting it would make the sentence ungrammatical for past duration, or change its meaning to a habitual action, a general statement, or even a future intention, depending on context.
For example, 我每天跑一个小时|Wǒ měitiān pǎo yī gè xiǎoshí (I run for an hour every day) describes a habit, lacking 了|le because it's not a single completed past event. So, for past, completed duration, 了|le is almost always necessary.
Q3: What if the object is a specific noun (e.g., a book title) instead of a general noun like 中文|Zhōngwén?
A3: When the object is a specific, definite noun (like 《红楼梦》|《Hónglóumèng》 - Dream of the Red Chamber), the 的|de construction (S + V + 了 + Duration + 的 + O) often becomes less natural or even ungrammatical. In such cases, verb repetition is strongly preferred.
  • ✅ Right: 我读《红楼梦》读了两个月|Wǒ dú 《Hónglóumèng》 dú le liǎng gè yuè (I read Dream of the Red Chamber for two months.)
  • ❌ Less natural/Incorrect: 我读了两个月的《红楼梦》|Wǒ dú le liǎng gè yuè de 《Hónglóumèng》 (This implies a 'two-month's worth' of the specific book, which sounds odd because the book's quantity isn't usually measured this way.)
This illustrates that 的|de works best when the duration can conceptually modify an amount or kind of the object, not a specific, singular item.
Q4: Can this duration pattern be used in questions?
A4: Yes, absolutely. You can form questions about duration by using interrogative words like 多长时间|duō cháng shíjiān (how long) or 多久|duō jiǔ (how long), replacing the duration phrase in the statement pattern.
  • 你学中文学了多久？|Nǐ xué Zhōngwén xué le duōjiǔ? (How long did you study Chinese for?)
  • 他们等了多长时间？|Tāmen děng le duō cháng shíjiān? (How long did they wait?)
Q5: What if the verb is disyllabic (two characters)? Does that change anything?
A5: The rules generally apply regardless of whether the verb is monosyllabic or disyllabic. For disyllabic verbs without an object, the pattern is S + V + 了 + Duration. For disyllabic transitive verbs with an object, verb repetition (e.g., 我学习汉语学习了三年|Wǒ xuéxí Hànyǔ xuéxí le sān nián) or the 的|de construction (我学习了三年的汉语|Wǒ xuéxí le sān nián de Hànyǔ) are used.
The core principles of V and 了 proximity, and handling of V+O structures, remain consistent. For example, 我研究了三个月|Wǒ yánjiū le sān gè yuè (I researched for three months) works perfectly with the disyllabic verb 研究|yánjiū.
Q6: How do you negate a past action with duration?
A6: To negate a past action, you use 没(有)|méi(yǒu) before the verb. When negating a duration, the 了|le particle is typically omitted from the sentence, as 没(有)|méi(yǒu) already carries the perfective aspect of negation. You state that the action did not happen for that duration.
  • 他没睡八个小时|Tā méi shuì bā gè xiǎoshí (He didn't sleep for eight hours.)
  • 我没学中文学一年|Wǒ méi xué Zhōngwén xué yī nián (I didn't study Chinese for a year.)
  • Note the absence of 了|le when 没(有)|méi(yǒu) is used for negation. This aligns with the rule that 了|le generally does not co-occur with 没(有)|méi(yǒu) for past actions.

Verb Repetition

Always repeat the verb if there is an object. It sounds much more natural.
⚠️

No 'le' with 'mei'

Never use {了|le} in a negative sentence. It is grammatically incorrect.
🎯

Time placement

The duration always comes after the verb, never before.
💬

Regional variations

Be aware that some people use '{钟|zhōng}{头|tóu}' instead of '{小|xiǎo}{时|shí}'.

Smart Tips

Repeat the verb to be safe.

{我|wǒ} {看|kàn} {了|le} {三|sān} {小|xiǎo}{时|shí} {书|shū} → {我|wǒ} {看|kàn} {书|shū} {看|kàn} {了|le} {三|sān} {小|xiǎo}{时|shí}

Use '{多|duō}{久|jiǔ}' at the end.

{你|nǐ} {学|xué} {了|le} {几|jǐ} {小|xiǎo}{时|shí}? → {你|nǐ} {学|xué} {了|le} {多|duō}{久|jiǔ}?

Drop the '{了|le}'!

{我|wǒ} {没|méi} {学|xué} {了|le} {三|sān} {年|nián} → {我|wǒ} {没|méi} {学|xué} {三|sān} {年|nián}

Repeat only the first part.

{我|wǒ} {跑|pǎo}{步|bù} {跑|pǎo}{步|bù} {了|le} {一|yī} {小|xiǎo}{时|shí} → {我|wǒ} {跑|pǎo} {步|bù} {跑|pǎo} {了|le} {一|yī} {小|xiǎo}{时|shí}

Pronunciation

le (short)

The {了|le} particle

It is a neutral tone, so it should be short and light.

Statement

{我|wǒ} {学|xué} {了|le} {三|sān} {小|xiǎo}{时|shí} ↘

Falling intonation for a completed fact.

Memorize It

Mnemonic

Remember: 'Verb-Object-Verb-Time'. Think of it as a sandwich: the verb is the bread, the object is the filling, and the time is the dessert.

Visual Association

Imagine a clock ticking. Every time you say a verb, imagine a little 'le' sticker being placed on the clock to show how much time has passed.

Rhyme

Verb then object, verb again, add 'le' and time, you're a ten!

Story

Yesterday, I studied Chinese. I said: '{我|wǒ} {学|xué} {汉|hàn}{语|yǔ} {学|xué} {了|le} {三|sān} {个|gè} {小|xiǎo}{时|shí}'. My friend asked: '{你|nǐ} {学|xué} {了|le} {多|duō}{久|jiǔ}?' I replied: '{我|wǒ} {学|xué} {了|le} {三|sān} {个|gè} {小|xiǎo}{时|shí}'.

Word Web

{小|xiǎo}{时|shí}{分|fēn}{钟|zhōng}{天|tiān}{月|yuè}{年|nián}{了|le}{没|méi}

Challenge

Set a timer for 5 minutes and describe 3 things you did today using the duration pattern.

Cultural Notes

In Beijing, people often use '{钟|zhōng}{头|tóu}' for 'hour' instead of '{小|xiǎo}{时|shí}'.

People in Taiwan frequently use '{钟|zhōng}{头|tóu}' as the standard term for 'hour'.

Cantonese speakers often carry over the 'hour' word '{钟|zhōng}' into their Mandarin.

The particle {了|le} evolved from the verb '{了|liǎo}' meaning 'to finish'.

FAQ (8)

No, never. {了|le} and {没|méi} are incompatible.

It helps clarify that the duration applies to the action, not the object itself.

No, '{钟|zhōng}{头|tóu}' is also very common in spoken Chinese.

If it's still happening, you might use a different structure like '{在|zài} + Verb'.

Most active verbs work, but some stative verbs don't take duration complements.

No, this structure is for past or completed actions.

No, '{过|guò}' is for experience, '{了|le}' is for duration.

Use '{多|duō}{长|cháng}{时|shí}{间|jiān}' or '{多|duō}{久|jiǔ}' after the verb.
