Hangul syllable Dyo

Read 됴 inside the old Korean word around it.

Hangul groups a consonant and vowel into a syllable block: ㄷ (a sound between d and t) + ㅛ (“yo”) makes 됴. The syllable 됴 in old Korean texts formed part of a word, not a sign with a meaning of its own. A 1447 Buddhist text, 석보상절, includes 됴ᄒᆞᆫ; a form from the 16th century, 됴야, is evidence for the related spelling 됴다 alongside 둏다.

둏다 meant both “to be good” and “to improve or recover.” Its spelling passed through 죻다 in the 18th century and 좋다 in the 19th century. The “improve or recover” sense disappeared by the 19th century, leaving the adjective sense. 됴 points to this word history; alone, it has no fixed translation.

Can 됴 appear in a Korean dialect?

A 1998 account records it in Yukjin, a regional Korean dialect.

It lists 됴 among syllables that can follow a consonant and gives 둏다 with the gloss “좋다.” This is a regional pattern documented in that account, not a general modern spelling.
