Hangul Syllable Geuls

긄 is a Korean syllable block; its word supplies the meaning. Its visible parts are ㄱ + ㅡ + ㄽ: an initial consonant, a vowel, and a final consonant cluster. On the standard two-set keyboard, an input method editor combines the typed jamo into this block.

The earliest surviving record of Hangul's creation dates to 1443, when King Sejong's court produced a 28-letter system. Hunminjeongeum, an explanatory guide to the new writing system, was completed in 1446 after three years of refinement. Korean differed from Chinese, yet Chinese characters were being used to write it; Hangul aimed to make Korean easier to learn and write.

How did Hangul's role change?

It grew from a new writing system into the official script for public documents. In 1894, Hangeul became official for public documents, and printing helped spread Hangeul newspapers, books, and other writing. Earlier Korean writing used Chinese characters; Hangul instead builds syllable blocks from jamo, its letters.

The same syllable can appear as one precomposed block or as an equivalent sequence of jamo. Fonts may change where the components sit, their shape, or their size, so a different-looking rendering can still be the same character.
