Hangul: the heart of the Korean language

When people first see the Korean alphabet, many assume the language must be difficult to learn. However, Hangul (한글) – the official writing system of both South and North Korea – is often considered one of the easiest alphabets in the world to master. And that’s no coincidence: it was designed with simplicity in mind.

A modern system with a rich history

Hangul was created in 1443 by order of King Sejong the Great, one of Korea’s most enlightened and beloved rulers. Before its invention, Koreans used Chinese characters (Hanja), which were complex and mainly accessible to the educated elite. King Sejong believed that everyone should have the opportunity to read and write in their own language. To make this possible, he commissioned the creation of an alphabet that would be simple, logical, and easy to learn.

In 1446, Hangul was officially introduced under the name Hunminjeongeum (훈민정음), which means “the correct sounds for the instruction of the people.” [1].

What is the Hangul alphabet made of?

At first glance, Hangul might look complex, but it’s actually a very logical and well-structured system. The alphabet consists of 24 basic letters: 14 basic consonants and 10 basic vowels. In addition, there are 5 double consonants and 11 combined vowels.

Unlike Western alphabets, Hangul isn’t written as a simple sequence of letters. Instead, the characters are grouped into syllabic blocks, with each block representing one syllable. The letters within each block fit together in a visually balanced and harmonious way, which gives the writing its clean and regular appearance.

For example, the word Hangul (한글) is made up of two blocks:
한 (han) and 글 (geul).

Each block is formed by combining individual letters:
한 (han) = ㅎ (h) + ㅏ (a) + ㄴ (n)
글 (geul) = ㄱ (g) + ㅡ (eu) + ㄹ (l)

A phonetic and logical alphabet

One of the most fascinating features of Hangul is that many of its consonant shapes were designed to visually represent how the mouth, tongue, and throat are positioned when pronouncing them. For example:

• ㄱ (g) represents the tongue touching the soft palate.
• ㅁ (m) shows the shape of closed lips.
• ㅅ (s) resembles teeth almost touching.

Hangul is a phonetic alphabet, meaning each letter corresponds closely to a specific sound. Once you’ve learned the letters and how they combine, you can read virtually any Korean word—even if you don’t know what it means!

This scientific design makes Hangul one of the most logical writing systems in the world. It’s no surprise that linguist Geoffrey Sampson once described it as “one of the most efficient writing systems ever devised” (Writing Systems: A Linguistic Introduction, 1985).

A cultural treasure recognized by UNESCO

Thanks to its brilliant design and historical significance, the original Hangul manuscript (Hunminjeongeum) has been inscribed in UNESCO’s Memory of the World Register. [2] In South Korea, Hangul is celebrated every year on October 9th, known as Hangul Day (한글날), a national holiday dedicated to Korean language and culture.
