What you will learn in this lesson
- Explain why Chinese characters were hard to use for the Korean language

- Understand who could read and write in old Korea, and who could not
- Learn basic words such as 한자, 한문, 글자 and 백성
Welcome, my friend. Come, sit down and have some tea. Before we talk about King Sejong, let me take you back to a time when Korea had a language, but no letters of its own.
A language without its own letters
People on the Korean Peninsula have spoken their language for a very long time. They sang songs, told stories, made laws and traded goods, all in Korean. But for most of that history, there was a big problem: there were no letters made for Korean.
When people wanted to write, they used Chinese characters. In Korean we call them 한자. Writing in the classical Chinese style is called 한문. For more than a thousand years, 한자 and 한문 were the main way to write in Korea, in government, in schools, in temples and in family records.
This was not because Koreans did not care about their own language. Chinese characters were simply the writing system that was used across East Asia at the time. Books of history, philosophy, medicine and religion were written in it. Learning 한문 opened the door to all of this knowledge.
Words for this lesson

- 한문 hanmun Literary Chinese; writing in classical Chinese style
- 글자 [글짜] geulja a letter, a written character
- 문자 [문짜] munja a writing system; script
- 백성 [백썽] baekseong the common people (of a kingdom)
- 양반 yangban the noble scholar class of the Joseon period
Why Chinese characters did not fit Korean
Imagine trying to write your own language with letters made for a completely different one. That was the situation in old Korea.
Chinese and Korean are very different languages. In Chinese, a word usually does not change its form. In Korean, we add many small endings to words. For example, the verb 가다 means 'to go'. From it we get 가요, 갔어요, 가면, 가니까, 가고 싶어요, and many more. Each ending adds meaning: politeness, past time, 'if', 'because', 'want to'.
Korean also uses small markers after nouns, such as 은, 는, 이, 가 and 을, 를. These show who does what in a sentence. Chinese characters had no simple way to write these little pieces. Also, the order of words is different. In Korean, the verb usually comes at the end of the sentence. So a writer had to think in Korean, then turn the idea into a Chinese-style sentence. It was like translating every time you wanted to write a note.
When I was a boy, my grandfather could still write beautiful 한자. But he used to say that learning them took his whole youth. Thousands of characters, my friend, thousands!

So many characters, so little time
Chinese characters are not like an alphabet. Each character usually stands for a meaning, not just a sound. To read ordinary books, a person needed to know several thousand characters. Learning them took many years of study.
Who had that much time? Mostly the families of the noble scholar class, called 양반, and people who worked in government, temples or special offices. Farmers, fishermen, servants and most women did not have the chance to study for years. So most ordinary people, the 백성, could not read or write.
This caused real problems in daily life. If a farmer could not read a notice from the government, he did not know the new rules. If someone was treated unfairly, it was hard to write a complaint to an official. Knowledge stayed in the hands of a small group.
Clever solutions: borrowing characters for sounds
Long ago, Korean writers were very creative. They did not give up. They found ways to bend Chinese characters so that they could write Korean.
The idea was simple but smart. Sometimes they used a character for its meaning. Other times they used a character only for its sound, ignoring its meaning. By mixing these two ways, they could write Korean words and even Korean endings.
Over the centuries, several systems grew from this idea. Scholars today usually group them into three: 이두, 향찰 and 구결. They were not separate alphabets. They were all ways of using Chinese characters for Korean.
Three ways of borrowing Chinese characters
| System | Main use | Simple description |
|---|---|---|
| 이두 | Official and administrative documents | Chinese-style text with Korean word order and Korean grammar pieces written with borrowed characters |
| 향찰 | Old Korean songs and poems | An attempt to write whole Korean sentences, using characters for both meaning and sound |
| 구결 | Reading Chinese books | Small marks or characters added between the lines of a Chinese text to show Korean endings |
All three systems used Chinese characters. None of them was easy for ordinary people.
이두: the language of offices
이두 was used for many centuries in documents such as reports, contracts and legal papers. Clerks in government offices knew it well. A text in 이두 looked like Chinese at first, but a trained reader could see Korean grammar hiding inside it.
It was useful, but it was still hard. You needed to know Chinese characters first, and then you needed to learn the special 이두 rules on top of that.
향찰: writing songs in Korean
In the old kingdom of Silla, people sang poems called 향가. Some of these were written down in 향찰. This system tried to write a whole song in the Korean language, line by line.
Today, scholars still discuss how to read some of these songs, because we cannot always be sure which character was used for meaning and which for sound. That tells you how tricky this system was. Only a small number of these songs have survived.
구결: little helpers for readers
Students who read Chinese classics often added small notes between the lines. These notes, called 구결, showed where the Korean endings should go when the text was read aloud. Over time, people even used shortened shapes of characters to write these notes more quickly.
구결 helped readers, but it did not help people who could not read Chinese characters at all.
Korean words with many endings
- 가요 gayo I go. / I'm going. Polite present ending.
- 갔어요 gasseoyo I went. The past tense is shown inside the word.
- 가면 gamyeon if (I) go One ending changes the meaning to 'if'.
- 가고 싶어요 gago sipeoyo I want to go. Korean builds meaning with endings and helper verbs.
- 백성이 글을 읽어요. [백썽이 그를 일거요] baekseongi geureul ilgeoyo. The people read writing. 이 and 을 are small markers that Chinese characters could not show easily.
Do you see the problem now? These endings are the heart of Korean. A writing system that could not show them clearly was like a coat that never quite fit.
The kingdom of Joseon
In 1392, a new kingdom was founded on the peninsula. It was called Joseon, or 조선 in Korean. Joseon lasted for more than five hundred years. Its rulers followed the ideas of Confucianism, which taught that a good king should care for his people like a parent cares for a child.
In Joseon, as before, the official written language was 한문. Laws were written in it. Exams for government jobs tested it. But the Confucian idea of a caring king raised a question: how can a king care for his people if they cannot even read his words?
This question would soon reach the heart of one remarkable king. His name was Sejong, the fourth king of Joseon. In our next lesson, I will tell you his story.
What this means for you as a learner
Even today, Korean has many words that came from Chinese characters. Words like 학교 (school), 한국 (Korea) and 문자 (writing system) all have roots in 한자. If you study Korean for a long time, you will notice these roots and they will help you guess new words.
But you do not need to learn 한자 to read Korean today. Thanks to Hangul, you can read every Korean word with just 24 letters. That is the gift that this story leads to.
