Hangul syllable Gyalm

걂 spells a Korean syllable; the surrounding word supplies meaning. The Unicode name uses “gyalm” as a label for this spelling, not as a translation. The block combines initial ㄱ, vowel ㅑ, and final ㄻ. These component letters are called jamo; its canonical Unicode decomposition is ᄀ + ᅣ + ᆱ. Final ㄻ is a consonant cluster within the same syllable, not another syllable.

Hangul was designed to write Korean speech; before it, methods such as Idu and hyangchal adapted Chinese characters to write Korean. Hangul was devised in 1443 and introduced in the 1446 Hunminjeongeum, a guide to the new writing system. Later, it appeared in teaching, religious, and practical books, sometimes alongside hanja, Chinese characters used in Korean texts.
