Hangul syllable Cyeok

On Dubeolsik, switch to Korean input and press C, U, Z.

On the standard two-set Dubeolsik Korean keyboard, C produces ㅊ, U produces ㅕ, and Z produces ㅋ. The input method joins them into one block; with English input active, the same keys produce Latin letters.

The precomposed block and its canonical jamo sequence use different code-point sequences, although a text system may display both as the same block. Normalize text before comparing them.

What does 쳨 mean?

It is a Korean syllable block whose word-level meaning depends on context.

The familiar Hangul forms ㅊ, ㅕ, and ㅋ occupy the initial-consonant, vowel, and final-consonant positions. These basic letters are called jamo; they combine in a fixed order to form a syllable block.

When was Hangul created, and why?

Hangul was announced in 1443 and explained in a book published in 1446.

Before Hangul, Korean writing used Chinese characters and systems such as Idu, which adapted Chinese characters to represent Korean. King Sejong and his scholars designed Hunminjeongeum as a more systematic, learnable way to write Korean. 쳨 belongs to that Hangul system; it is not descended from a Chinese character.

Hangul's social standing shifted over time. During the Joseon period, official elites favored Chinese-character writing, while Hangul spread through everyday writing, women's letters, Buddhist publications, and novels. It entered official documents during the 1894 Kabo Reform.
