Hangul Syllable Ddu

Switch to a Korean IME, then enter ㄸ followed by ㅜ.

Korean input composes a block in consonant–vowel order. On keyboards whose consonant keys share plain and tense pairs, use Shift for ㄸ, then type ㅜ. Entering the parts in the opposite order will not produce this block.

Is 뚜 an emoji?

No. It is a Korean Hangul syllable block, not an emoji.

Its documented lineage is the Hangul writing system: King Sejong's project was created in 1443 for people shut out of reading and writing Korean through Chinese characters, then explained in the 1446 Hunminjeongeum publication. The purpose was practical literacy, so 뚜 is a spelling unit rather than a picture-sign.

As of 2026, the sources checked do not establish a separate first attestation or historical/regional meaning for isolated 뚜. Its connected history is ㄸ: diachronic research links Korean tense stops to earlier consonant-cluster patterns, so 뚜 inherits an older sound contrast rather than introducing a new sign.

What does 뚜 mean?

Alone, 뚜 has no single English-style definition.

In normal Korean vocabulary, it is one syllable inside words such as 뚜껑 and 뚜렷이. The surrounding syllables determine the word's meaning.

When 뚜 arrives alone, ask for context. The documented sound-effect reading belongs to the repeated form 뚜뚜, not automatically to one copy of the syllable.
