Hangul syllable gyilm

It represents a written syllable, not a complete word. Its Hangul parts—component letters called jamo—are initial consonant ㄱ, vowel ㅣ, and final consonant cluster ㄻ (ㄹ + ㅁ). A syllable block can form part of a longer Korean word; the word gives it meaning.

Hangul was created in 1443 under King Sejong; in 1446 he published a guide called 훈민정음 that explained the new script. It was designed to make Korean easier to write than earlier methods that adapted Chinese characters for Korean, including 이두, 구결, and 향찰. Hangul later appeared in Buddhist and Confucian books, practical publications, and everyday labels; it became an official national writing system in 1894.

How do I type 긞?

A Korean keyboard input method assembles its component letters into one block. Enter ㄱ, ㅣ, then ㄹ and ㅁ in a Korean input method editor (IME); it combines the last two into the final cluster ㄻ.

The single character 긞 encodes the whole syllable. A decomposed version uses separate Hangul letters; if an app lacks the support to shape them, they may appear separately instead of forming one block.
