Every October 9, Korea takes a day off to thank an alphabet. Say that out loud to a friend back home and watch their face.
It's called Hangul Day (한글날, Hangeul-nal), and it marks the year 1446, when King Sejong made the new script public. Plenty of countries have holidays for wars won or kings born. We have one for the letters we use to order tteokbokki, read the subway map, and type ㅋㅋㅋ at 2 a.m. I've always liked that about this country.
The holiday has a strange little history of its own, by the way. It was a day off for decades, then in 1991 the government dropped it from the list of public holidays because, apparently, Koreans had too many days off. (People who have worked in a Korean office may laugh at that.) It stayed a regular workday until 2013, when it came back. So yes, the alphabet got its holiday cancelled and then un-cancelled.
Quick facts
- Hangul Day: October 9, a public holiday again since 2013
- The script was published in 1446 as Hunminjeongeum
- 24 letters in everyday use: 14 consonants, 10 vowels
- National Museum of Korea: general admission is free
- National Hangeul Museum: closed for renovation, check its website
Before Hangul, writing was for the few
For centuries, if you wanted to write in Korea, you wrote in Chinese characters, which Koreans call hanja (한자). Fine if you were a scholar with years to spare. Not so fine if you were a farmer, a merchant, or pretty much anyone else.
There was also a bigger problem. Korean and Chinese are built completely differently. Korean glues endings and particles onto words to show who did what to whom, and hanja had no clean way to show those bits. So you could speak Korean your whole life and still have no practical way to write down what you'd just said.
Sejong's answer was to make something new. He worked on it with scholars at his court, and in 1446 the script was published in a book called Hunminjeongeum (훈민정음), roughly "the proper sounds for teaching the people." The preface says, more or less, that ordinary people have things they want to say but can't put them in writing, and that the king felt sorry for them. Every Korean kid learns that line.
Not everyone was thrilled, of course. A senior scholar named Choe Manri sent the king a long letter of protest in 1444, arguing that abandoning Chinese characters was a step backwards. Sejong went ahead anyway. I think about that sometimes when people say new ideas are always welcomed.
So how does it actually work?
Here's the part I find genuinely clever.
Some of the basic consonants are pictures of your mouth. ㄱ (g/k) is the back of your tongue lifting toward the roof of your mouth. ㄴ (n) is the tongue tip touching behind the upper teeth. ㅁ (m) is closed lips, basically a box. ㅅ (s) is a tooth. ㅇ is the throat. Want a harsher, breathier k? Stick one extra line on ㄱ and it turns into ㅋ. Same trick turns ㄴ into ㄷ. Once you notice it you can't unsee it.
Vowels are even more philosophical, which is very fifteenth century of them. Sejong's scholars built them out of a dot (heaven), a flat line (earth) and an upright line (a human standing between the two). Lean the dot against the standing line and there's your ㅏ. The dot has since shrunk into a tiny stroke, so good luck spotting heaven in there now.
How many letters? Twenty-four in everyday use. Fourteen consonants, ten vowels. The twist is that you don't write them in a row like English. You pack them into little squares, a syllable each, so ㅎ, ㅏ and ㄴ squeeze together into 한, and ㄱ, ㅡ, ㄹ turn into 글. Those two squares? That's the word Hangul.
People love to call it "the most scientific alphabet in the world," and I get why. But let me be honest with you. Learning to sound out Hangul is fast. Maybe an afternoon, maybe a weekend. Learning Korean is another story entirely.
What it looks like in real life
Most of us learned to read by chanting 가, 나, 다, 라 with a teacher, one syllable at a time. After that, Hangul just disappears into the background. It's on bus stops, on the pink notices taped inside apartment elevators, on the little stickers labelling school cubbies. You stop seeing it.
Where it gets fun is texting. Koreans drop the vowels all the time. ㅋㅋㅋ is someone laughing, and if you get ㅋㅋㅋㅋㅋㅋㅋ you've really landed the joke. ㅎㅎ is gentler, the thing you send your boss. ㅇㅇ means "yeah." ㄱㅅ is a lazy "thanks" (from 감사, gamsa). Older folks grumble about it. Teenagers basically speak it.
If you're learning, my advice is simple. Learn the letters first, and quit leaning on romanization as soon as you can, because it lies to you about sounds like ㅓ (eo) that English doesn't have. Then read things you actually care about. K-pop lyrics. Drama subtitles. The menu at a gimbap shop. Reading 김밥 and realizing it says "gimbap" feels better than any worksheet.
One warning. Korean spelling and Korean pronunciation don't always match. 신라, the old kingdom, is written sin-ra but said "Silla." You'll run into things like that constantly, and it's normal to be confused.
Spending the day in Seoul
I'd normally send you to the National Hangeul Museum (국립한글박물관) out in Yongsan, but its official website says the whole museum is closed for a renovation and expansion project right now, so check the site before you go. The good news is that the much bigger National Museum of Korea (국립중앙박물관) sits in the same park, and general admission is free. One museum rarely fills a holiday anyway. After that, take the subway up to Gwanghwamun. You can't miss Sejong; he's the giant golden man sitting in the middle of the square. Most tourists take a photo and leave, but walk around behind him and there's a staircase down to a free exhibition about his life and the alphabet.
Honestly, though, the best Hangul Day activity costs nothing. Walk around Insadong or any old neighborhood and try to read the shop signs, slowly, one block at a time. You'll get plenty wrong. That's fine.
Oh, and holiday hours do weird things in Korea. Look them up the night before.
So, a day off for an alphabet. After you've spent an afternoon squinting at signs and actually reading a few of them, I don't think it'll seem so odd anymore.
