Hangul Syllable Jyoh

죻 is a Hangul syllable preserved in the old spelling 죻다.

For the historical spelling 죻다, the key is its place between 둏다 and modern 좋다 (“to be good”). Hangul writes Korean syllables as blocks made from consonant and vowel letters, so 죻 is one syllable, not the whole word.

The chain begins with 둏다 in 15th-century texts. An 18th century sound change called palatalization—shifting ㄷ to ㅈ before an i-like sound—produced 죻다. By the 19th century, the older pronunciation written 죠 had merged with the one written 조, and the spelling had become 좋다. The older word also meant “improve” or “recover” as a verb that takes no object; that sense later disappeared. Other recorded spellings include 둇-, 둇ㅎ-, and 좃ㅎ-, which write the final ㅎ with ㅅ.

Should I use 죻 instead of 좋?

Use 좋다 for modern Korean; reserve 죻다 for historical text.

Read 죻 in context: the documented word-level use is the older spelling 죻다, not a modern standalone word. If you mean “good” in present-day Korean, use 좋다.
