Hangul syllable doe

Its meaning comes from the Korean word or construction around it. In 되다 (“to become”), forms with 되 can also express obligation, as in 해야 되다, or permission, as in 가도 되다.

Hangul was deliberately created as a writing system for Korean and announced in 1443. A 1446 explanatory book, Hunminjeongeum, described its purpose—making Korean easier to write—and how syllables are built. Those dates describe Hangul, not the first recorded use of this block.

When do I use 되 instead of 돼?

Use 돼 when the form expands to 되어. Keep 되 before endings such as -고 and -면: 되고, 되면. Write 돼요, not 되요.
