About Hangul and this quiz
Hangul (한글) is the Korean alphabet, created by King Sejong in 1443. It is famously logical: 14 basic consonants and 10 basic vowels combine into syllable blocks, so most learners can read Korean within a day or two of practice. This quiz shows sounds in Revised Romanization — the official system used on Korean road signs and in textbooks. Start with the basic 24 letters, then switch to all 40 to add double consonants (ㄲ ㄸ ㅃ ㅆ ㅉ) and compound vowels (ㅐ ㅔ ㅘ ㅢ …).
An alphabet that was designed, not inherited
Almost every writing system in use today drifted into its present shape over centuries. Hangul did not. It was created deliberately in 1443 under King Sejong, with a published explanation of how and why it works, so that ordinary people could read and write without mastering thousands of Chinese characters. It is one of very few alphabets whose inventor, date and design rationale are all documented.
The consonant shapes are pictures of the mouth making the sound. ㄱ shows the back of the tongue against the soft palate, ㄴ the tip of the tongue at the ridge behind the teeth, ㅁ the shape of the closed lips. Related sounds add strokes to the same base: ㄷ is ㄴ with a line, ㅌ is ㄷ with another.
How letters become syllable blocks
Hangul letters are not written in a line like Latin ones. They are stacked into square blocks, one block per syllable, with a fixed arrangement: the initial consonant goes top-left, the vowel to its right or underneath depending on whether the vowel is vertical or horizontal, and a final consonant sits at the bottom. 한 is ㅎ plus ㅏ plus ㄴ; 글 is ㄱ plus ㅡ plus ㄹ.
This is why Korean looks dense and character-based at first glance and turns out to be an alphabet on closer inspection. Fourteen basic consonants and ten basic vowels combine into every syllable in the language, which is why most learners can sound out written Korean within a day or two even without understanding a word of it.
Working through this quiz
Start with the basic 24 letters. They cover the great majority of what you will meet in ordinary text.
Then move to all 40, which adds the doubled consonants and the compound vowels formed by joining two basic ones.
Sounds are shown in Revised Romanization, the official system used on Korean road signs and in textbooks.
Romanization is an approximation, not a pronunciation guide. Korean consonants sit between the English pairs, so ㄱ is neither exactly g nor exactly k.
Write each letter by hand once as you learn it. Stroke order and direction make the shapes stick far better than recognition alone.
Hangul is the Korean alphabet, created by King Sejong the Great in 1443. It has 14 basic consonants and 10 basic vowels that combine into syllable blocks — for example ㅎ+ㅏ+ㄴ makes 한 (han). It is considered one of the most logical writing systems in the world.
How long does it take to learn Hangul?
Most learners can read Hangul after a few hours of practice — it was deliberately designed to be easy. Play a few rounds of the basic 24 letters, then add the double consonants and compound vowels with the “All (40)” setting.
What do sounds like “g/k” or “eo” mean?
They are Revised Romanization, the official system for writing Korean sounds with Latin letters (used on Korean road signs and in textbooks). Some letters like ㄱ sound between g and k depending on position, so both are shown.
How many letters are there in Hangul altogether?
Modern Hangul has 40 jamo in total: 19 consonants (14 basic plus 5 double consonants like ㄲ and ㅆ) and 21 vowels (10 basic plus 11 compound vowels like ㅐ, ㅘ and ㅢ). This quiz starts with the basic 24 and covers all of them in the “All (40)” setting.
Why is Korean written in syllable blocks?
King Sejong designed Hangul so that letters stack into square blocks, each representing exactly one syllable — 한국 (Korea) is two blocks, two syllables. This makes the rhythm of a word visible at a glance and keeps text compact. Once you know the letters, reading blocks becomes automatic with a little practice.
Do I need to learn Hanja (Chinese characters) to read Korean?
No. Modern Korean is written almost entirely in Hangul; Hanja appears only occasionally in newspapers, academic texts or to clarify names. Learning the 40 jamo in this quiz is genuinely enough to sound out nearly any Korean text you'll encounter, from K-pop lyrics to street signs.
