忙 vs 累: busy vs tired
忙 (máng) describes a full schedule or being occupied with tasks, while 累 (lèi) refers to physical or mental fatigue. Learners often confuse them because in English 'tired' can be used as a general excuse, but in Chinese the reason must match the word: use 忙 for time constraints and 累 for exhaustion.
忙 and 累 are two distinct adjectives in Chinese that are often confused by beginners. 忙 (máng) relates to time management: it means you have many things to do and little free time. 累 (lèi) relates to energy level: it means you feel physically or mentally worn out. Although in English one might say 'I'm too tired to go out' when actually busy, Chinese requires you to specify the real reason. Choosing the wrong word can cause misunderstanding.
When to use each
Use 忙 when you have a lot to do, your schedule is full, or you are occupied with tasks. It focuses on the amount of work or commitments, not your energy level. 忙 is also commonly used as a polite excuse to decline invitations, even if the busyness is relative.
In polite conversation, 忙 can be used somewhat flexibly as a social excuse without needing to be literally overwhelmed.
Use 累 to describe physical fatigue (e.g., after exercise), mental exhaustion (e.g., after studying), or general weariness. It is about the result of exertion, not the cause. 累 is appropriate when your body or mind feels drained, regardless of how busy you are.

Common mistakes
- Using 累 to mean 'busy' because you have no free time – use 忙 instead.
- Using 忙 to describe feeling exhausted after exercise – use 累.
- Saying '我很忙累' (wǒ hěn máng lèi) – these two adjectives cannot be directly combined with 很 in that order; use '我又忙又累' (I am both busy and tired) instead.
- Using 累 as a polite excuse to decline an invitation when your schedule is actually free – 忙 is more appropriate in that social context.
FAQ
- When do I use 忙 vs 累 to explain why I can't go out?
- If your calendar is full and you have no free time, use 忙. If you have free time but feel too exhausted to go out, use 累. In Chinese, the reason must accurately reflect the main issue.
- Can I say '我很忙累' to mean 'I am busy and tired'?
- No. 忙 and 累 are separate adjectives and cannot be directly combined with 很. The correct way to say 'busy and tired' is '我又忙又累' (wǒ yòu máng yòu lèi) or use a phrase like '我既忙又累'.
- Is it always correct to use 很忙 to say 'I'm busy'?
- Yes, 很忙 (hěn máng) is the standard way to say 'busy'. Similarly, 很累 (hěn lèi) is standard for 'tired'. The 很 does not always mean 'very'; it is often used to make the adjective sound neutral in affirmative sentences.
- What is the difference between '我累了' and '我很累'?
- '我累了' (wǒ lèi le) emphasizes a change of state – 'I have become tired' or 'I'm tired now' – and often implies a recent onset of fatigue. '我很累' (wǒ hěn lèi) describes a current state of being tired without focusing on the change.
