Hangul syllable Geonh

It spells one Korean syllable; the surrounding word supplies meaning. Hangul groups its letters into square blocks, each spelling a syllable. In a word, 걶 contributes that syllable while the whole word carries its meaning.

Fonts can arrange or size the parts inside a Hangul block differently, so the same character may look slightly different across fonts. Unicode also supports the equivalent spelling as separate Hangul letters, which an input method or text processing can expose.

How is 걶 built?

It combines ㄱ, ㅓ, and the final cluster ㄶ. These are Hangul letters: ㄱ begins the syllable, ㅓ is its vowel, and ㄶ is its ending. In Korean spelling, 받침 means the consonant at the bottom of a syllable block; 겹받침 is a compound final consonant made of two letters, as ㄶ is. That is the difference between 걶 and 건, which ends in ㄴ, or 걷, which ends in ㄷ.

Hangul was created in 1443 and published with its explanatory book, Hunminjeongeum, in 1446 to make Korean writing easier to learn and use. The script later carried practical, educational, religious, and literary writing; that is Hangul's history, not a meaning change in this exact block.
