Hangul syllable Caenj

By itself, 챉 is a Korean syllable, not a word.

It combines ㅊ (a consonant), ㅐ (a vowel), and ㄵ (a two-consonant ending) in one Hangul block. At the end of a word or before another consonant, ㄵ is usually heard as “n”; its ㅈ is not pronounced separately there.

Before Hangul, Korean writers used Chinese characters and adapted character-based methods such as idu and hyangchal to write Korean. Hangul was designed to fit Korean more directly, with letters arranged into syllable blocks; it was created in 1443 and explained in a 1446 publication. 챉 is one possible block made from those parts, not a separately invented sign.
