Hangul Syllable Ddeulm

Use Korean input: enter ㄸ, ㅡ, then ㄹ and ㅁ.

The input method combines those Hangul jamo into one syllable block. The final ㄹ and ㅁ form a single ending. Software that accepts conjoining jamo can also represent the block as ᄄ, ᅳ, and ᆱ.

What does 뜲 mean by itself?

It gives one Korean syllable, not a word to translate by itself. The surrounding Korean word or sentence tells you what it means. If someone sends only this block, there is too little context to choose a word meaning.

Hangul was devised by King Sejong in 1443. In 1446, Hunminjeongeum, a guide explaining the new script's purpose and principles, was published. Before Hangul, Korean was written using Chinese characters and methods adapted from them. Hangul groups alphabetic letters into syllable blocks; their square appearance does not mean they descended from Chinese characters.

After 1446, Hangul publications included Buddhist scriptures, followed by Confucian works and practical books. Chinese characters remained important in official documents. Hangul became Korea's official national writing system in 1894; under Japanese rule, it lost that status in 1910.
