Hangul Syllable Kyung

It has no fixed meaning alone; the surrounding Korean word supplies it. This block is built from three Hangul jamo, or letters: ㅋ at the start, ㅠ as the vowel, and final ㅇ. In Korean, they contribute an aspirated k, the “yu” sound, and ng as in “sing.” Remove final ㅇ and it becomes 큐, a different syllable.

Hangul was devised under King Sejong to make Korean easier to write and learn than relying on Chinese characters. The first record of Hunminjeongeum, the new script, dates to 1443; a book explaining its purpose and design was published in 1446. Hangul later became the everyday writing system for Korean, while 큥 remained one buildable syllable rather than a word with a fixed definition.

How do I type 큥?

Switch to Korean input and type z, b, then d. On the standard Korean two-set keyboard, called Dubeolsik, those keys enter ㅋ, ㅠ, and ㅇ; the IME combines them into one block as you type.

Unicode can represent the same syllable as three decomposed jamo, ᄏ + ᅲ + ᆼ, instead of the precomposed block 큥. A Hangul-aware renderer shapes that sequence as one block; if the parts stay separate, the app or font is not applying that shaping.
