Hangul Syllable Ddot

It is one written Korean syllable, not a self-contained message.

It combines ㄸ, the tense counterpart of ㄷ made with a tighter articulation, with vowel ㅗ and final consonant ㅌ. If someone sends it alone, ask what they meant. To type 똩 on a Korean two-set keyboard, press Shift+E, H, X.

Hangul, the script behind this block, was devised in 1443 to write Korean directly; its earliest record appears in the Sejong Annals. Before it, Idu, Hyangchal, and Gugyeol adapted Chinese characters to write Korean. The 1446 Hunminjeongeum guide explains how letters form syllable blocks. Hangul spread through letters, petitions, household labels, songs, and books while official records continued in Chinese; it became Korea’s official national writing system in 1894. Tense ㄸ developed from earlier consonant clusters in the second half of the 15th century. Scholars debate whether Mongolian imperial script Phags-pa, based on Tibetan writing, influenced Hangul’s design.

Why can 똩 appear as three separate letters?

The same syllable can be stored as one block or as three joining letters.

Unicode can represent 똩 as the conjoining Hangul letters ᄄ + ᅩ + ᇀ, a sequence of jamo. Text normalization may keep those letters separate. A font shapes them into a block; if it cannot join them correctly, they may appear apart.
