How to use 是 (shì, “to be”) in Mandarin Chinese？

This is probably one of the very first questions that you’d encounter in your journey of Chinese learning, and here we have you all covered! Let’s start with the basics:

Like in English, you would say, “I am teacher” (with no “a”) in Mandarin. And if you want to ask someone “Are you a teacher?” you would say:

Did you notice that you don’t have to change the word order to make a yes-no question in Mandarin? All you need to do is add a 吗 (ma) at the end of a statement to turn that into a yes-no question. What’s even better is that you do not need to conjugate 是 (shì) or any verbs for past/future in Mandarin. Sounds great, right?

However, there is a catch: you cannot use 是 (shì) with adjectives, which is probably one of the most common mistakes learners make. For example,

Instead of this, what you’re supposed to say is:

Why? Let’s read on!

是 (shì, be) is a verb that connects two, nounsNo definition set for nounsLorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. but remember, nouns and pronounsNo definition set for pronounsLorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. only, never adjectivesNo definition set for adjectivesLorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.. For example,

Here, 是 (shì, be) connects 他 (tā, he) and 老师 (lǎoshī, teacher). You can think of 是 (shì, be) as the “=” sign. What you’re saying is that 他 (tā, he) = 老师 (lǎoshī, teacher). And if you want to make a negative sentence, simply add 不 (bù, not) before 是 (shì, be), like this:

Like we said at the beginning of this post, we don’t need to change the word order to make a yes-no question in Mandarin. All you do is add a 吗 (ma) at the end of a statement. If you’re feeling fancy, you can also use the A-not-A structure, where you repeat the 是 (shì, be):

So you’re literally saying, “Is he or is he not a teacher?” Easy right?

Now that we discussed the role of 是 in these sentences, you may have seen structures where 是 in structures like these is omitted. This is done mainly in spoken language and you may want to read our post on nominal predicates that explains this in more detail.

是 in most cases is not obligatory. There are two cases in which 是 cannot be omitted:

• With demonstrative adjectives:

  这是手机。

  (Zhè shì shǒu jī.)

  This is a cell phone.

• When we classify an item to a category:

  苹果是一种水果。

  (Píng guǒ shì yī zhǒng shuǐ guǒ. )

  Apples are a kind of fruit.

In many ways, 是 (shì, be) acts like “be” in English, but do not use 是 (shì, be) with adjectives.

是 (shì, be) can also be attached to the end of a sentence to make a tag question. Tag questions with 是 (shì, be) are for confirmation of a previous statement. To make a tag question with 是 (shì, be), we can use either 是吗 (shìma) or 是不是 (shìbùshì). For example,

Or:

Now, let’s talk about something that’s a bit more challenging.

是...的 (shì…de) structure is quite versatile. It is similar to the “it is…that…” pattern in English. You can use that to emphasize when, where, how, with who, etc. an event occurred. However, 是...的 (shì…de) cannot be used to emphasize the grammatical object No definition set for object Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.in a sentence. Look at the following example sets: the first sentenceNo definition set for sentenceLorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. is how you’d normally say it, and the second is how you use the 是...的 (shì…de) structure to emphasize part of the sentence.

  (Zhèxiē guāndiǎn shì hěn zhèngquè de.)

  These points of view are quite right.

  I study English literature.

Remember, since 是...的 (shì… de) cannot be used to emphasize a grammatical object, you cannot say:

As you can see in all these examples, 是...的 (shì…de) is a very useful structure. You simply add 是  (shì) right in front of the phrase you want to emphasize, and 的 (de) at the end of the sentence. And in all those cases, you can even drop the 是  (shì)! Just make sure you never drop 的 (de)! This structure is quite useful, right?

You should not use 是 (shì) to express that something exists in / on / at a place:

We can see the basic pattern is: subject + 在  (zài) + location. 在  (zài) is the only verb needed here.

You could also read our post on 在 (zài) where we discuss how 是 (shì) cannot be used to express existence in a place!

Finally, in Mandarin, there are no counterparts to the "there is / are" pattern in English. 有 (yôu, to have) will cover it all. So remember, when talking about "there is something at some place," the Mandarin sentence will be structured like "some place has something."

In this post, we discussed one of the most important verbs in Mandarin: 是 (shì, be). It is like the English “be” in many ways, but the most important difference is that you don’t use that for connecting adjectives. The 是...的  (shì...de) structure is useful for emphasizing a particular part of a sentence.

Do not use 是 (shì) to express existence in / on / at a place nor to express “there is / are.”
