When learning a language, you’ll definitely have to learn new vocabulary, grammar patterns, and pronunciations. In some cases, you might have to learn a new alphabet or writing system! Many languages use unique writing systems: for example, Ukrainian uses Cyrillic and Japanese uses kana. But today, we want to dive into the Korean writing system, Hangul (or Hangeul)!

Screenshot of the Korean course reading tab. The text at the top says "Let's learn Hangeul! Get to know the main writing system in Korean." Below the text is a blue button that reads "Learn the letters" and below that a 4 by 4 chart of white tiles for the different Korean syllable characters. Each tile has the Korean character, and below it the English letter or letters representing the sound. Screenshot of a lesson from the the Korean course reading tab. At the top it says "Build the character" and below it is a blue microphone icon and H-A-N (English letters). In the center of the screen is a large square with a dotted blue outline and below it are three tiles of different Korean characters. Two of the tiles have been dragged to the top left and top right of the large square, and the bottom half of the square is gray with the dotted blue outline.

Hangul has 24 letters, and the letters combine into syllable blocks, which we sometimes call characters. “Banana”, for example, has three syllables: ba-na-na. In Korean, this would be 바나나. Three syllables = three blocks!

This might be different from what you’re used to, but Duolingo has tools for learning new writing systems. Plus, we recently updated our Korean course to put more focus on everyday spoken Korean and additional practice with tricky concepts.

Whether you’re actively learning Korean or are simply interested in the language, here are five things every learner should know about Hangul:

1. Every letter only makes one sound*

*(There are a few exceptions, but we’ll save those for another time!)

Many people claim you can learn Hangul in one day. Maybe that’s a bit of an exaggeration, but the idea is, it’s pretty easy to memorize the sounds!

In English, the letter “a” sounds different in “father,” “about,” “age,” the list goes on and on. But that’s not a problem with Korean! Each letter only makes one sound. That “ah” sound is always written with “ㅏ,” and “ㅏ” is only pronounced like “ah.” Ahh, isn’t that nice?

Typing is a breeze, too! The Korean keyboard will stack the letters for you as you type in the letters. The layout is easy too: the consonants are on the left side, and the vowels are on the right side.

2. The consonants are based on the shape of your tongue

This is tougher to actually see, but trust the experts on this one: the consonants in the Hangul alphabet were drawn to mimic the shape of the tongue when pronouncing them. How cool is that?

For instance, when you pronounce the consonant ㄱ (the “g” sound), the back of your tongue goes up to touch the back of your mouth, so you’re making the shape of ㄱ with your tongue!

3. Hangul was created to improve literacy

Hangul was created in the 1400’s by King Sejong, the fourth king of the Joseon Dynasty. Back then, Chinese characters were used to write Korean. But not only were the Chinese characters difficult to learn, they didn’t even match up with how people actually spoke. King Sejong wanted a better system specifically for Korean, which would boost literacy and let more people do tasks like filing claims, writing letters, or keeping records.

4. The characters used to be written from top to bottom

Did you know that Korean used to be written from top to bottom? Nowadays it’s written from left to right, but you might still see some vertical writing at international movie festivals hosted in Korea. If they need both English and Korean subtitles for a film, the English subtitles can be displayed on the bottom as usual, and then the Korean subtitles are along the right side, written from top to bottom.

5. There’s a national holiday just for Hangul

The alphabet is so beloved that South Korea takes a day off for Hangul Day every year on October 9th. That day was chosen because that’s when the document of this rad new writing system (known as the Hunminjeongeum) was officially published in 1446. Five centuries later, it still holds up!

So what are you waiting for?

Duolingo’s Korean course is the fourth most popular language for English speakers. And we’ve recently made some improvements to the course, so go check it out! You can even start with the tab that says to do our specialized lessons that teach you how to read and write Hangul.

Note: Notice two different ways to spell Hangul? Hangeul is the officially recognized spelling by the National Institute of Korean Language (this is what you'll see in our course), but Hangul has become the more popular spelling, and what many learners (old and new) may be familiar with.
