Hanja Basics for Korean Learners
Meet Hanja, the Chinese characters behind many Korean words: how Koreans name them (물 수), basic characters, the days of the week, and the initial-sound rule.
Professor Hangyeol · The history, culture and advanced expressions of HangeulWhat you will learn in this lesson
- Explain what Hanja are and where you still see them in Korea
- Read characters the Korean way, with meaning and sound (훈음)
- Learn about twenty basic characters, including the days of the week
- Understand why 女 is 여 in 여자 but 녀 in 남녀
When I was a boy, my grandfather wrote characters with a brush every morning, and I watched the ink spread on the paper. You do not need a brush today, my friend. But a little Hanja will make your Korean much deeper, and I promise it is more fun than it looks.
What are Hanja?
Hanja (한자, 漢字) are Chinese characters as used in Korea. Before Hangul was created in the 15th century, Koreans wrote almost everything in Chinese characters. Even after Hangul appeared, Hanja stayed important in official and scholarly writing for a long time, and older books and newspapers often mixed Hanja and Hangul in the same sentence.
Today, everyday Korean is written almost entirely in Hangul. But Hanja did not disappear. They live inside the Sino-Korean words you use every day. In South Korea, the Ministry of Education keeps a list of 1,800 basic characters for middle and high school education, and many people take private Hanja proficiency tests.
You will still see Hanja in a few places: on some signs and newspaper headlines (to save space or avoid confusion), in names (most Korean given names have Hanja), on traditional buildings, at family ceremonies, and in dictionaries, which show the Hanja next to each Sino-Korean word.
How Koreans name a character: 훈음
In Korea, a character is named with two parts: first its meaning in native Korean (훈, 訓), then its sound in Sino-Korean (음, 音). For example, 水 is called 물 수: 물 is the meaning (water) and 수 is the sound you hear in words like 수영 (swimming) and 생수 (bottled water).
This way of naming is very helpful for learners, because the name itself teaches you both the meaning and the reading. When a Korean asks you, "이름 한자가 뭐예요?" (What are the Hanja of your name?), people answer in this style, such as "빛날 희" for 熙.
The days of the week
| Hanja | Name (훈음) | Meaning | Day |
|---|---|---|---|
| 月 | 달 월 | moon | 월요일 |
| 火 | 불 화 | fire | 화요일 |
| 水 | 물 수 | water | 수요일 |
| 木 | 나무 목 | tree, wood | 목요일 |
| 金 | 쇠 금 | metal, gold | 금요일 |
| 土 | 흙 토 | earth, soil | 토요일 |
| 日 | 날 일 | sun, day | 일요일 |
요일 itself is 曜日. You already knew seven characters without realizing it.
金 has a second reading: as a family name it is read 김, not 금. That is why the most common Korean surname is written with the same character as Friday. So when you see 金 on a nameplate, read it 김.

In South Korean standard spelling, some Sino-Korean syllables change when they come first in a word: ㄴ before ㅣ/ㅑ/ㅕ/ㅛ/ㅠ becomes ㅇ, and initial ㄹ becomes ㄴ or ㅇ.
- 女 (녀): 남녀 in the middle, but 여자 at the start.
- 年 (년): 매년, 내년 in the middle, but 연도, 연말 at the start.
- 老 (로): 경로 in the middle, but 노인 at the start.
- This rule is why one character can have two Korean spellings.
- 여자와 남자 yeojawa namjawomen and men
- 남녀 공용 화장실 namnyeo gongyong hwajangsilunisex restroom
- 노인과 경로석 noingwa gyeongnoseokthe elderly and the priority seat for the elderly

How to study Hanja without stress
You do not have to learn to write thousands of characters. For most learners, the goal is to recognize the meaning of common syllables. Here is a gentle plan.
1. Learn characters through words you already know, not as a list. When you learn 출구, also learn 出 = go out. 2. Use the 훈음 names (날 출, 들 입). They are short and easy to remember. 3. Look at the Hanja in the Standard Korean Dictionary when a word confuses you. 4. Start with about 100 high-frequency characters. Numbers, days of the week, directions and body words are a good beginning.
