Why Is 所 Hiding in 所以、所有、厕所?

Added: 2026-06-01

[00:00:00]There is a tiny character hiding inside some of the most common Chinese words.

[00:00:07]You see it in and that is only the beginning. You also see it in and even in expressions like At first, these words may look completely unrelated.

[00:00:37]Most learners simply memorize them one by one.

[00:00:42]So, means so. So, means all.

[00:00:47]So, means toilet.

[00:00:49]So, means so-called and then they move on.

[00:00:54]But today, let's slow down and ask a different question.

[00:00:59]Why is the same character so appearing in all these words? Is it just sitting there? Or is it quietly helping shape the meaning?

[00:01:11]By the end of this video, you will not look at so the same way again. Because so has two very important sites and once you see these two sites, many Chinese words become much easier to remember.

[00:01:32]Let's begin with the easiest side of so.

[00:01:36]In many modern Chinese words, so points to a place, a location, or a site connected with a function.

[00:01:46]Look at these examples.

[00:01:49]So, toilet. This is a place connected with toilet use.

[00:01:57]So, clinic. This is a place connected with medical consultation.

[00:02:05]Yanjiusuo research institute. This is a place connected with research.

[00:02:13]Zhùsuǒ residence. This is a place where someone lives.

[00:02:20]And we also have Shìwùsuǒ office or firm.

[00:02:26]Pàichūsuǒ local police station.

[00:02:31]Chǎngsuǒ place or venue. So, in many words, when suǒ comes at the end, it gives the feeling of a place for that action, purpose, or function. That's why cèsuǒ, zhěnsuǒ, yánjiūsuǒ, zhùsuǒ belong to the same family. They are not the same kind of place, but they share the same word building idea.

[00:03:01]Something plus suǒ, a place connected with that thing. This does not mean every word with suǒ is a place. That would be too simple. But this is the easiest doorway into the character because it gives you something concrete, a restroom, a clinic, a research institute, a home, a local police station.

[00:03:29]Once you see that, cèsuǒ stops being a word to memorize. It becomes an example of how Chinese builds meaning through parts.

[00:03:41]Now comes the more powerful side of suǒ because suǒ does not stand at the end.

[00:03:48]Sometimes it stands before a verb.

[00:03:52]And when suo appears before a verb, it often creates the feeling of what is or that which is. For example, jian, to see, becomes suo jian, what is seen or what one sees.

[00:04:12]wen, to hear, becomes suo wen, what is heard or what one hears.

[00:04:20]So, when Chinese says suo jian suo wen, you can feel it as what one sees and what one hears. Suddenly, this phrase does not feel so mysterious. It has a clear shape.

[00:04:35]Let's try more examples.

[00:04:38]suo shuo, what is said.

[00:04:41]suo zhi, what is known.

[00:04:45]suo xiang, what is thought.

[00:04:48]suo zuo, what is done.

[00:04:51]So, if you see ta suo shuo de hua, you can understand it as the words that he said. And if you see wo suo zhi dao de shi qing, you can understand it as the things that I know.

[00:05:08]You do not need to translate every sentence word by word. But this way of feeling suo is extremely useful. It takes an action and packages it into something you can point to and talk about. Not just see, but what is seen.

[00:05:29]Not just say, but what is said. Not just know, but what is known. So, here is the simple clue.

[00:05:39]Don't only ask what suo means. Ask where suo is standing.

[00:05:45]When suo stands at the end of a word, it often points to a place, like 厕所, 诊所, 研究所. But, when 所 stands before a verb, it often creates the feeling of what is as in 所见, 所闻, 所知, 所说. This clue will help us understand the next few words.

[00:06:11]Now, let's apply this to a very useful word.

[00:06:15]所谓.

[00:06:17]In modern Chinese, 所谓 means so-called. But, let's look inside it. 谓 can mean to say, to call, or to refer to.

[00:06:30]So, 所谓 carries the feeling of what is called or what people call.

[00:06:37]And from there, we get the modern meaning so-called. For example, 所谓 成功 不是 赚钱.

[00:06:47]So-called success is not just making money.

[00:06:51]Here, 所谓 成功 means what people call success. But, here is an important detail. In English, so-called often sounds negative or sarcastic. In Chinese, 所谓 is not always negative.

[00:07:09]Sometimes, it can sound skeptical. But, sometimes, it simply introduces a concept. For example, 所谓 成长 就是 学会 承担 责任.

[00:07:24]So-called growth means learning to take responsibility.

[00:07:29]This sentence does not have to sound sarcastic. It can simply mean when we talk about growth, what do we usually mean? So, 所谓 is a great of suo plus verb.

[00:07:44]Wait means to call. Suo wait Suo wait means what is called. And in modern Chinese, it becomes so-called.

[00:07:53]Now, let's move to another very common word.

[00:07:58]Suo you In modern Chinese, Suo you means all or all of. For example, Suo you the ren dou dou la. All the people have arrived.

[00:08:13]Wo xi huan Suo you the shu. I like all the books.

[00:08:20]Suo you the wen ti dou jie jue la.

[00:08:24]All the problems have been solved.

[00:08:28]For learners, the most important thing is simple.

[00:08:32]Suo you equals to all or all of. That is the modern meaning you should remember.

[00:08:39]You means to have or there is.

[00:08:44]So, Suo you can be felt as connected to what is had, what there is, or the whole set involved. You do not need to over analyze it every time. So, Suo you the ren, all the people.

[00:09:02]Suo you the shu, all the books.

[00:09:05]Suo you the wen ti, all the problems.

[00:09:09]The main takeaway is Suo you gathers everything in the group.

[00:09:17]Let's look at three examples where Suo plus verb is very clear.

[00:09:24]The first one is Suo zai.

[00:09:28]Zai means to be at or to be located.

[00:09:32]So, Suo zai has the feeling of where something is located. For example, Wo the place where the company is located.

[00:09:46]And where the problem lies.

[00:09:52]Notice that wèntí suǒzài doesn't have to mean a physical location. Can mean the real point of the problem.

[00:10:03]The second word is shǔ means to belong to or to be affiliated with.

[00:10:11]So, what belongs to or what is affiliated with something.

[00:10:18]For example, the department one belongs to.

[00:10:28]The company one belongs to.

[00:10:31]This word often appears in formal or official settings. Now, this phrase means as far as I know.

[00:10:44]Let's break it down.

[00:10:46]Jù means according to or based on.

[00:10:50]Wǒ means I or me.

[00:10:53]Zhī means to know.

[00:10:55]Suǒzhī means what is known. So, jù wǒ suǒzhī means according to what I know.

[00:11:05]This is such a good phrase because you can feel the structure clearly.

[00:11:10]Now, suǒ is not invisible anymore. You can see exactly what it is doing.

[00:11:18]We have come to one of the most common words of all.

[00:11:23]In modern Chinese, suǒyǐ means so or therefore.

[00:11:29]You often see it in this pattern.

[00:11:32]Yīnwèi suǒyǐ because something so something. For example, Yīnwèi xiàyǔ suǒyǐ wǒ méi qù.

[00:11:42]Because it rained, I didn't go.

[00:11:46]Another example, Yīnwèi tài guì, suǒyǐ wǒ méi mǎi. Because it was too expensive, I didn't buy it. Now, if you have watched my earlier videos on Yǐ and Chù, this word becomes even more interesting.

[00:12:06]The Yǐ in suǒyǐ is connected to an older meaning of Yǐ, to use, by means of or on the basis of. So, suǒyǐ can be felt as something like the reason or basis by which something happens.

[00:12:23]That's why it naturally became connected with cause and result.

[00:12:30]But don't force this too much in daily Mandarin. Native speakers usually treat suǒyǐ as one complete word meaning. For modern learners, the key point is simple. Suǒyǐ is a fixed conjunction. It links a reason to a result. And in daily Mandarin, that is how you should learn and use it.

[00:12:52]Now, I want to be careful here. We should not pretend that every modern word can be perfectly explained by breaking apart the characters in a simple formula.

[00:13:06]That can become misleading.

[00:13:08]But knowing that Suǒ has a long grammatical life in Chinese help us understand why it also appears in more formal patterns such as zhī suǒyǐ shì yīnwèi the reason why something is because something.

[00:13:28]Wǒ zhī The reason why I study Chinese is because I like Chinese culture.

[00:13:42]This sounds more formal and more deliberate than Because I like Chinese culture, I study Chinese.

[00:13:58]So, remember use suoyi as so or therefore, but recognize that suo also appears in deeper written patterns like yinwei.

[00:14:16]Once you understand suo, some advanced-looking phrases become easier to read. For example, there's nothing one does not know, meaning this person knows everything.

[00:14:36]There's nothing one cannot do, meaning this person can do anything.

[00:14:44]There's no place where it is not present, means everywhere or omnipresent.

[00:14:52]At first, wu suo bu something may look difficult, but it has a clear feeling.

[00:14:59]There is nothing that is not.

[00:15:03]You may also see one's actions or conduct. Here, suo zuo means what is done. Suo wei means what is done or what one does. Together, suo zuo suo wei refers to a person's actions or behavior.

[00:15:23]For example, His actions disappointed everyone.

[00:15:34]And in more formal written Chinese, you may see bei something suo something or wei something suo something.

[00:15:45]For example, He's respected by everyone.

[00:15:53]A more everyday version would be da jia dou zun jing ta. Everyone respects him.

[00:16:05]This story is well known by people.

[00:16:08]A more everyday version might be Many people know this story. So, remember, understanding suo does not mean using it everywhere. It means recognizing it when you see it.

[00:16:26]Sometimes it is everyday, sometimes it is formal. Sometimes it is written and polished, and when you recognize it, Chinese becomes easier to read.

[00:16:38]If this video helped you finally see what suo is doing, comment below I see suo now.

[00:16:47]And tell me which tiny Chinese character you want next.

[00:16:52]Because in Chinese, sometimes the smallest words carry the biggest surprises.

[00:16:58]Zai jian.
