Hangul Syllable Ddut

It is a Korean syllable block; its letters don't define a word.

Hangul, the Korean writing system, fits consonant and vowel letters into blocks that represent syllables. The Hangul letters in 뚵 are ᄄ (the starting consonant), ᅮ (the vowel), and ᇀ (the ending consonant). On screen, a font draws this syllable as one text block. These parts show how the syllable is built, not what a word containing it means. Use the surrounding Korean word and sentence for that meaning.

When did Hangul appear in the historical record?

A royal chronicle called Sejong Sillok records it in 1443.

In 1446, Hunminjeongeum, an explanatory book, set out the script's purpose and how its letters form syllable blocks.

Before 1443, Korean writing used Chinese characters, called Hanja, and methods such as Idu, which adapted those characters to write Korean words and grammar. Hangul was designed as a more accessible way to write Korean. Its use spread from government and Buddhist texts to letters, everyday books, and legal documents across social ranks. It became the national script in 1894; Japanese annexation in 1910 ended that status. These dates describe Hangul's history as a writing system, not a documented origin date for this particular block.
