Hangul syllable Ddyus

On a standard Korean 2-beolsik keyboard, press Shift+E, then B, then T.

Switch to Hangul input first. The Korean input method combines those keystrokes into one syllable block as you type.

What does 뜟 mean?

In a Korean word, 뜟 contributes one syllable; the whole word supplies the meaning.

It is made from three jamo, or individual Hangul letters: ᄄ, the initial consonant; ᅲ, the vowel; and ᆺ, the final consonant. “Ddyus” is Unicode’s romanized label for those parts, not a Korean word’s translation.

Hangul was created in Joseon under King Sejong in 1443. Korean writing had relied heavily on Chinese characters; Hangul gave Korean a script designed for its sounds. The explanatory book Hunminjeongeum Haeryebon, published in 1446, describes the letters and how syllables are built from an initial, a vowel, and an optional final consonant. 뜟 follows that ordinary pattern.

What does 뜟 mean when someone sends it?

Read it with the surrounding Korean text; alone, ask what the sender intended.

Inside a Korean word, 뜟 supplies one syllable. In a message by itself, it does not show which word or input the sender meant; ask for context.

Someone may be showing the syllable or an input result, but that is a guess from the situation, not a meaning carried by 뜟.
