Hangul syllable Ggwalb

It spells one Korean syllable in a block of letters.

Hangul groups the letters for a syllable into one block. In 꽓, the vowel ㅘ is formed from ㅗ and ㅏ; ㄲ starts the block and ㅂ ends it. The block shows the spelling of one syllable, while the surrounding Korean text gives it context.

How do I type 꽓?

Use a Korean input method and enter the letters in order.

On Dubeolsik, a Korean keyboard layout, press Shift+R, H, K, Q: Shift+R enters ㄲ, H then K enter ㅗ and ㅏ to form ㅘ, and Q enters ㅂ. The input method joins them into one block. If composition is still in progress or the letters are entered out of order, separate jamo can remain visible.

Where did Hangul syllable blocks come from?

Hangul grouped letters into blocks when the writing system was created.

Hangul's letters are dated to 1443; the completed Hunminjeongeum work introducing the script is dated to 1446. The system was designed to write Korean with its own letters, grouped into square blocks that each represent a syllable.

A modern Hangul syllable can also be represented as separate conjoining jamo, the Korean letters that form it. Some older Hangul syllables use jamo sequences without a single block. Font design can change how letters sit inside a block, and an uncommitted or decomposed sequence can show them separately.
