Hangul syllable Caek

챜 is one Hangul syllable; the surrounding word supplies its meaning.

Hangul letters are called jamo and are grouped into syllable blocks. 챜 combines ㅊ as its first consonant, ㅐ as its vowel, and ㅋ as its final consonant. By itself, the block gives a syllable but not a dependable word-level meaning; the surrounding Korean spelling tells you how it functions.

Under King Sejong in Joseon, the Korean kingdom of the time, Hangul was made as an alphabet people could learn and use to write Korean speech, which Chinese characters fit poorly. A surviving record dates to 1443; the Hunminjeongeum, a book explaining the letters and syllable structure, appeared in 1446. Hangul later became the everyday writing system for Korean.
