What are Chinese auxiliary verbs?

Chinese auxiliary verbs are words that come before a main verb to show desire, willingness, obligation, ability, permission, or possibility.

They are also called modal verbs or 能願動詞 néngyuàn dòngcí.

For beginners, remember this basic pattern first:

Pattern Meaning
Subject + Auxiliary verb + Main verb Subject wants to / can / should / must do something.

For example:

Chinese Pinyin English
我想去台灣。 wǒ xiǎng qù Táiwān I want to go to Taiwan.
我可以去台灣。 wǒ kěyǐ qù Táiwān I can go to Taiwan. / I may go to Taiwan.
我應該去台灣。 wǒ yīnggāi qù Táiwān I should go to Taiwan.

1. Three main meanings

This lesson groups Chinese auxiliary verbs into three beginner-friendly types.

Type Meaning Common words
Willingness / desire want, hope, be willing to 想、想要、要、肯、願意、希望
Obligation / necessity should, have to, need to, must 應該、得、需要、必須、須
Ability / permission / possibility can, may, be able to 能、可以、會

The same English word “can” or “want” may have several Chinese translations. The correct word depends on the meaning and situation.

2. 想 xiǎng: want to / would like to

「想」is used before a verb to mean “want to” or “would like to.” It often sounds like a thought, wish, or plan that is still flexible.

Pattern Meaning
Subject + 想 + Verb phrase Subject wants to do something.
Chinese Pinyin English
我想放棄。 wǒ xiǎng fàngqì I want to give up.
我想學中文。 wǒ xiǎng xué Zhōngwén I want to learn Chinese.
你想去哪裡? nǐ xiǎng qù nǎlǐ Where do you want to go?

Be careful:「想」can also mean “to miss someone” when it is followed by a person.

Chinese Pinyin English
我想你。 wǒ xiǎng nǐ I miss you.

3. 想要 xiǎngyào: want / want to

「想要」can be followed by a noun or a verb phrase. It clearly means “want.”

Pattern Meaning
Subject + 想要 + Noun Subject wants something.
Subject + 想要 + Verb phrase Subject wants to do something.
Chinese Pinyin English
我想要一個桃子。 wǒ xiǎngyào yí ge táozi I want a peach.
我想要去美國旅行。 wǒ xiǎngyào qù Měiguó lǚxíng I want to travel to the United States.

「想要」is a little more direct than「想」, but still softer than「要」in many situations.

4. 要 yào: want / be going to / need to

「要」has several meanings. It can mean “want,” “be going to,” or “need to / have to,” depending on context.

Pattern Possible meaning
Subject + 要 + Noun want something
Subject + 要 + Verb phrase want to / be going to / need to do something
Chinese Pinyin English
他要一個蘋果。 tā yào yí ge píngguǒ He wants an apple.
我要去台灣。 wǒ yào qù Táiwān I want to go to Taiwan. / I am going to Taiwan.
你要聽我的話。 nǐ yào tīng wǒ de huà You have to listen to me.

Compared with「想」,「要」can sound more decided, direct, or necessary.

5. 想 vs 要 vs 想要

Word Feeling Example
want to; softer; still thinking 我想去台灣。
想要 want; can take a noun or verb phrase 我想要一個桃子。
want / going to / need to; more direct 我要去台灣。

For beginners, use「想 + verb」for “want to do,” and「想要 / 要 + noun」for “want something.”

6. 敢 gǎn: dare to

「敢」means “dare to.” It shows courage or willingness to do something risky, difficult, or challenging.

Pattern Meaning
Subject + 敢 + Verb phrase Subject dares to do something.
Chinese Pinyin English
他敢挑戰權威。 tā gǎn tiǎozhàn quánwēi He dares to challenge authority.
我不敢說。 wǒ bù gǎn shuō I do not dare to say it.

7. 肯 kěn: be willing to

「肯」means “be willing to.” It often suggests that someone agrees to do something even though it may take effort, patience, or sacrifice.

Chinese Pinyin English
他肯努力學習。 tā kěn nǔlì xuéxí He is willing to study hard.
他不肯道歉。 tā bù kěn dàoqiàn He is unwilling to apologize.

「不肯」is very common. It means “refuse to” or “be unwilling to.”

8. 願意 yuànyì: be willing to

「願意」also means “be willing to.” It sounds more direct and neutral than「肯」.

Chinese Pinyin English
我願意幫你。 wǒ yuànyì bāng nǐ I am willing to help you.
我願意與你度過一生。 wǒ yuànyì yǔ nǐ dùguò yìshēng I am willing to spend my whole life with you.

「願意」is often used for personal willingness or agreement.

9. 希望 xīwàng: hope to / hope that

「希望」means “hope.” It can be followed by a verb phrase or a clause.

Pattern Meaning
Subject + 希望 + Verb phrase Subject hopes to do something.
Subject + 希望 + Clause Subject hopes that...
Chinese Pinyin English
我希望成為一個科學家。 wǒ xīwàng chéngwéi yí ge kēxuéjiā I hope to become a scientist.
我希望你可以來。 wǒ xīwàng nǐ kěyǐ lái I hope you can come.

10. 應該 yīnggāi: should

「應該」means “should.” It is useful for suggestions, expectations, or reasonable judgments.

Pattern Meaning
Subject + 應該 + Verb phrase Subject should do something.
Chinese Pinyin English
你應該練習中文。 nǐ yīnggāi liànxí Zhōngwén You should practice Chinese.
我們應該早點出門。 wǒmen yīnggāi zǎo diǎn chūmén We should leave earlier.

For beginners,「應該」is the safest and most useful word for “should.”

11. 應當 yīngdāng / 應 yīng: formal “should”

「應當」and「應」also mean “should,” but they sound more formal. They are common in writing, rules, speeches, announcements, or serious advice.

Word Feeling Example
應該 common and useful 你應該練習中文。
應當 formal; serious 你應當早點起床。
written; formal 你應遵守規則。

In daily conversation, use「應該」first.

12. 得 děi: have to

「得」is pronounced「děi」when it means “have to” or “must.” It is common in spoken Chinese.

Pattern Meaning
Subject + 得 + Verb phrase Subject has to do something.
Chinese Pinyin English
你得去醫院。 nǐ děi qù yīyuàn You have to go to the hospital.
我得走了。 wǒ děi zǒu le I have to go now.

Do not confuse「得 děi」with「得 de」in complements, such as「說得很好」.

13. 需要 xūyào: need / need to

「需要」means “need.” It can be followed by a noun or a verb phrase.

Pattern Meaning
Subject + 需要 + Noun Subject needs something.
Subject + 需要 + Verb phrase Subject needs to do something.
Chinese Pinyin English
人類需要水。 rénlèi xūyào shuǐ Humans need water.
你需要休息。 nǐ xūyào xiūxí You need to rest.

14. 必須 bìxū: must / have to

「必須」means “must” or “have to.” It is stronger than「應該」and is often used for rules, requirements, or important obligations.

Chinese Pinyin English
你必須上學。 nǐ bìxū shàngxué You must go to school.
你必須戴安全帽。 nǐ bìxū dài ānquánmào You must wear a helmet.

「須」is a formal written word meaning “must.” In beginner daily speech, use「必須」or「得」instead.

15. 能 néng: can / be able to

「能」means “can” or “be able to.” It often focuses on ability, conditions, or possibility.

Pattern Meaning
Subject + 能 + Verb phrase Subject can do something.
Chinese Pinyin English
我能自己完成作業。 wǒ néng zìjǐ wánchéng zuòyè I can finish the homework by myself.
你今天能來嗎? nǐ jīntiān néng lái ma Can you come today?

「能」often depends on whether the situation allows it or whether the person has the ability.

16. 可以 kěyǐ: can / may / be allowed to

「可以」means “can” or “may.” It often focuses on permission or whether something is allowed.

Chinese Pinyin English
我可以進去嗎? wǒ kěyǐ jìnqù ma May I go in?
這裡可以拍照。 zhèlǐ kěyǐ pāizhào You can take photos here. / Taking photos is allowed here.

When asking for permission,「可以」is usually more natural than「能」.

17. 會 huì: can / know how to / will

「會」has two important beginner meanings:

  • can / know how to: learned ability
  • will: future possibility or prediction
Meaning Chinese Pinyin English
learned ability 我會說中文。 wǒ huì shuō Zhōngwén I can speak Chinese.
future / prediction 我會去歐洲。 wǒ huì qù Ōuzhōu I will go to Europe.

「我會說中文了」means “I can speak Chinese now.” The「了」shows a change of situation.

Chinese Pinyin English
我會說中文了。 wǒ huì shuō Zhōngwén le I can speak Chinese now.

18. 能 vs 可以 vs 會

Word Main meaning Example
ability / condition allows 我能自己完成作業。
可以 permission / allowed 這裡可以拍照。
learned skill / will 我會說中文。

19. How to make auxiliary verbs negative

Most auxiliary verbs are negated with「不」before the auxiliary verb.

Positive Negative English
想去 不想去 want to go / do not want to go
可以去 不可以去 can go / cannot go
應該去 不應該去 should go / should not go

For ability with「會」, you can also add degree words before「會」.

Chinese Pinyin English
我不太會游泳。 wǒ bú tài huì yóuyǒng I am not very good at swimming. / I cannot swim very well.

In Chinese,「不太」modifies「會」directly: 不太會 = not very good at / not very able to.

20. Common grammar notes

Auxiliary verbs have some important grammar limits.

Rule Example Note
Most auxiliary verbs are followed by verbs, not nouns. 我想去。 「想要」and「要」can be followed by nouns.
Auxiliary verbs usually do not repeat. 我會說。 Do not say「我會會」.
Auxiliary verbs usually do not take「了、著、過」directly. 我會說中文了。 Here「了」marks the whole situation, not just「會」.

Some words can be auxiliary verbs in one sentence and normal verbs in another sentence. For example,「要了三個蘋果」means “asked for / ordered three apples,” not “wanted-ed three apples.”
