Hangul syllable Ddweob

It is one Korean syllable, not a word by itself. The block combines initial consonant ㄸ, vowel ㅝ, and final consonant ㅂ. In Hangul, these parts are grouped to write a spoken syllable. The label Ddweob names this syllable; it is not an English translation. Read it as part of the Korean word around it.

How did Hangul develop?

Hangul was made to write Korean speech more directly. Earlier methods such as Idu, Gugyeol, and Hyangchal adapted Chinese characters to write Korean, and could be difficult to learn. The first record of Hunminjeongeum appears in Sejong Sillok in 1443; an explanatory book with that name was published in 1446.

Hangul later appeared in Buddhist scriptures and Confucian translations. The Korean word 한글 became widely used as the script's name in 1928.

A connection between Hangul vowel design and Phags-pa is debated. A 2009 study in the Journal of Korean Linguistics argues that Phags-pa influenced parts of the vowel design. This proposal concerns Hangul's design, not a claim that 뛉 descends from a Chinese character or a Phags-pa sign.

How do I type 뛉 on a Korean 2-set keyboard?

Enter ㄸ + ㅝ + ㅂ in a Korean IME. On the Dubeolsik layout, press Shift+E, N, J, Q; the input method composes those jamo into 뛉.

A font can change the strokes without changing the character. An editor or normalization tool may show the component jamo separately; that is a different representation of the same syllable.
