What is Hangul, and how does the drill work?
Hangul is the Korean alphabet — famously one of the most logical writing systems ever designed. There are just 40 letters (19 consonants and 21 vowels), and they stack into square syllable blocks: 한 is ㅎ + ㅏ + ㄴ. Unlike Chinese or Japanese, there are no readings to memorize — once you know the letters, you can sound out almost any Korean word, which is why most learners read their first words within days.
Start on the Chart tab and tick the letter groups you want to practice (basic consonants and basic vowels first). Then switch to Practice: a letter appears, you type its romanized sound — g, eo, wa — and the drill advances the moment you get it right. Miss one and you see the answer immediately; the same letter comes back a few cards later until it sticks.
Tick the groups you want to practice, then switch to Practice.
Frequently asked questions
How long does it take to learn Hangul?
Hangul was designed to be easy — the classic saying is that "a wise man can learn it in a morning". Realistically, most learners recognize all 40 letters within a few days of short drill sessions, and read simple syllable blocks fluently within a couple of weeks. The tense (doubled) consonants and compound vowels take the longest; drill them as their own groups.
Which romanization does the drill use?
Revised Romanization — the official South Korean standard you see in textbooks and street signs (ㅓ = eo, ㅡ = eu, ㅈ = j). Where a letter genuinely has two common readings, both are accepted: r or l for ㄹ, and ui or eui for ㅢ. Letters whose sound changes at the end of a syllable (ㄱ sounding like k) show that as a hint under the letter.
Why do I see single letters instead of syllable blocks like 한?
Because the letters come first: every syllable block is just two or three of these 40 letters stacked into a square, so once ㅎ, ㅏ and ㄴ are automatic, reading 한 is assembly rather than memorization. Drill the letters until they are instant, then start sounding out real words — that jump is surprisingly quick.
Does the drill save my progress?
Your letter-group selection is saved in your browser (no account needed), so the drill opens where you left off. The session stats — seen, correct, accuracy, streak — deliberately reset each visit: the drill is about instant recall today, not long-term statistics.
