Learn hangul by playing
Hangul was designed to be learnable in an afternoon, and it very nearly is. Nineteen consonants, twenty-one vowels, and a rule for stacking them into blocks.
Play in KoreanLetters first, blocks second
The early levels give you the jamo on their own — ㄱ, ㄴ, ㅏ, ㅗ — because those are what your fingers type. The top tier switches to syllable blocks like 가 and 호, which is how Korean is actually written: a consonant and a vowel packed into one square. Seeing ㄱ and ㅏ become 가 is the moment hangul clicks.
Why the shapes make sense
The consonant shapes are diagrams of the mouth making the sound, which is why ㄱ, ㅋ and ㄲ look related — they are the same sound with more air and more force behind it. The Study Room groups them that way rather than alphabetically.
