Hangul Alphabet: 한글
Hangul (한글) is the official writing system of South Korea, created in 1443 by King Sejong the Great (세종대왕). Unlike Chinese characters, Hangul is a phonetic alphabet — each symbol represents a sound. This lesson covers the complete alphabet: all 10 basic vowels, 11 compound vowels, 14 consonants, tensed and aspirated variants, vowel harmony, and how syllables are built. Most learners can read and write basic Hangul within a few hours!
1 About Hangul (한글)
Hangul was scientifically designed — an extraordinary achievement for its time. King Sejong assembled a team of scholars called the Hall of Worthies (집현전) to create a writing system that ordinary people could learn quickly, unlike the complex Chinese characters used by scholars of the era.
What makes Hangul remarkable is that the shapes of the consonants mimic the physical position of the mouth and tongue when producing each sound. This logical design means the alphabet is internally consistent and highly learnable.
The complete Hangul system contains:
- 10 basic vowels (기본 모음)
- 11 compound vowels (복합 모음)
- 14 basic consonants (기본 자음)
- 5 tense consonants (쌍자음)
- 5 aspirated consonants (거센소리)
2 Basic Vowels (모음)
Every Korean syllable contains exactly one vowel. The 10 basic vowels are the foundation of the entire system. Each one attaches to the silent consonant ㅇ when written alone, producing a pure vowel sound.
King Sejong designed the vowel shapes to reflect the physical position of the mouth. Three base shapes — ㆍ (heaven / dot), ㅡ (earth / flat line), and ㅣ (human / upright line) — combine to form all vowels.
3 Compound Vowels (복합 모음)
Compound vowels are formed by combining two basic vowels. They are written as a single character and produce a blended sound. There are 11 compound vowels, making Korean's total vowel count 21. Memorising which two vowels form each compound helps you read unfamiliar words.
4 Basic Consonants (자음)
Korean has 14 basic consonants. Each consonant was designed to represent the shape of the mouth or throat when producing that sound — a remarkable feat of linguistic engineering. Each consonant name follows a pattern: it starts with the consonant sound and ends with the consonant sound (e.g., ㄱ is named 기역 — it starts and ends with the "k" sound).
5 Syllable Blocks (음절)
One of the most elegant features of Hangul is how syllables are formed. Rather than writing letters in a line (like English), Korean letters are grouped into syllable blocks. Each block represents one spoken syllable.
Every syllable must contain at least one consonant and one vowel. An optional final consonant — called 받침 (batchim) — can be added at the bottom of the block.
| Structure | Example | Reading | Meaning |
|---|---|---|---|
| Consonant + Vowel | 가 | ga | go (verb stem) |
| Consonant + Vowel + Consonant | 한 | han | Korean (prefix) |
| Silent ㅇ + Vowel | 아 | a | ah! (exclamation) |
6 Tense (Double) Consonants — 쌍자음
Five Korean consonants have a "tensed" version formed by doubling the basic consonant. They are pronounced with tightened throat muscles and no puff of air (unaspirated). Native speakers describe the feeling as holding your breath slightly before releasing the sound.
7 Compound Batchim (겹받침)
Korean syllables can also end with a compound batchim (겹받침) — two consonants stacked together in the final position. There are 11 compound batchim. When speaking, only one consonant is pronounced at a time, depending on what follows.
| Batchim | Example Word | Meaning | Note |
|---|---|---|---|
| ㄺ | 읽다 | to read | Pronounce ㄱ; ㄹ carries to next syllable before vowel |
| ㄵ | 앉다 | to sit | Pronounce ㄴ; ㅈ carries to next syllable before vowel |
| ㄻ | 삶 | life | Pronounce ㅁ; ㄹ carries to next syllable before vowel |
8 Aspirated Consonants — 거센소리
Four Korean consonants have an "aspirated" version — produced with a strong burst of air. In English, you naturally aspirate consonants at the start of stressed syllables: the "p" in pot is aspirated, while the "p" in spot is not. Korean makes this distinction phonemic, meaning it changes the meaning of words entirely.
