Chinese grammar 所 (suǒ) structural particle

The character 所 (suǒ) has a few different uses. In this article we’re looking at its use as a structural particle. Don’t worry if you don’t know what that term means - you can still use 所 correctly without understanding the jargon around it!

Nominal constructions with 所

A nominal construction is something that can be used as a noun. 所 is used to form one kind of nominal construction. The basic structure for this is:

所 [verb] 的

As you can see, 所 is placed right before the verb and 的 right after it. This creates a meaning like “that which is [verb]ed”. Here are some short examples for this structure:

所吃的

suǒ chī de

that which is eaten

所知道的

suǒ zhīdào de

that which is known

所失去的

suǒ shīqù de

that which is lost

With this 所 construction, you can make compound terms that act as nouns in a sentence. We can expand the basic structure to include this:

所 [verb] 的 [noun]

Here are some examples of these compound nouns:

所吃的菜

suǒ chī de cài

the food that is eaten

所知道的事实

suǒ zhīdào de shìshí

the facts that are known

所学到的知识

suǒ xuédào de zhīshi

the knowledge that is learned

Note how each of these is nominal. That is, they could all function as nouns in a sentence. Now let’s expand the structure a little bit more again:

[noun] 所 [verb] 的 [noun]

The first noun is the agent. This means it is doing the action of the verb. The second noun is the patient. This means it is receiving the action of the verb. Let’s have a look at some examples for this structure:

我所吃的菜

wǒ suǒ chī de cài

the food I eat

他们所知道的事实

tāmen suǒ zhīdào de shìshí

the facts that they know

我们所学到的知识

wǒmen suǒ xuédào de zhīshi

the knowledge we have learned

Again, each of these makes a ‘chunk’ that can work as a noun in a sentence. Let’s do just that and have a look at some full example sentences:

You might have noticed that in all the examples given here, 所 could be left out and it would still be grammatical. This shows that 所 is actually optional. It can be used to make something clearer or to add some formality, but it is not essential.

Some common compounds with 所

Whilst in theory any verb could be used with 所, there are a few that appear with it more commonly than others. These have almost become fixed vocabulary items. Some of the most common are:

所谓

suǒwèi

so-called

所得

suǒde

that which is gained

所有

suǒyǒu

"that which exists" (i.e. all)

所以

suǒyǐ

"that which because of" (i.e. so)

所想

suǒ xiǎng

"that which is thought" (i.e. one's thoughts)

Let’s have a look at some example sentences for these 所 compound words:
