Auxiliary Verbs

Learn how to use auxiliary verbs (modal verbs) in Chinese with proper adverb placement

What Are Auxiliary Verbs?

Auxiliary verbs (also known as modal verbs) are helper verbs that modify the main verb to express ability, possibility, permission, obligation, or desire. In Chinese, they function similarly to English modal verbs like “can,” “should,” “must,” and “want to.”

Similarities with English

English Auxiliary Verbs
  • can, could
  • should, ought to
  • must, have to
  • will, would
  • may, might
Chinese Auxiliary Verbs
  • 会 (huì) – can, know how to
  • 要 (yào) – want to, need to
  • 应该 (yīnggāi) – should
  • 可以 (kěyǐ) – may, can
  • 想 (xiǎng) – want to

Like in English, Chinese auxiliary verbs immediately precede the main verb they modify. However, there’s an important difference in adverb placement.

Key Difference: Adverb Placement

In Chinese, adverbs come before the auxiliary verb, not before the main verb as they often do in English.

English: She really wants to go.
Chinese:非常 想去。 (Adverb before auxiliary verb)
Not: 她 想 非常 去。 (Incorrect placement)

This is a crucial grammatical rule for constructing natural-sounding Chinese sentences.

Sentence Structure with Auxiliary Verbs

The standard word order for sentences with auxiliary verbs follows a specific pattern: Subject + (Adverb) + Auxiliary Verb + Main Verb + (Object).

S + (Adverb) + AV + V + (O)

Adverb modifies the auxiliary verb, which then modifies the main verb
