Hangul Jongseong Tikeut

It puts ㄷ in the final-consonant position.

받침 (batchim) is the consonant at the end of a Korean syllable. Here, ᆮ marks the position for ㄷ: it is a building block, not a word.

Hangul gave Korean a way to write its sounds without relying on Chinese characters; its design is documented in 1443. The 1446 Hunminjeongeum Haerye, a guide to the script, derives ㄷ's shape from ㄴ plus a stroke and illustrates its sound with the first consonant of the Korean reading of 斗, a Chinese character. In early Hangul texts, ㄷ also linked some Chinese-character spellings with Korean words.

Why does ᆮ look different on its own?

It is a trailing component, not a complete syllable.

Unicode treats ᆮ as a trailing jamo, or T: it joins a leading consonant and vowel as the final part of a syllable block. On its own, it lacks that context; Unicode's filler behavior can make it render differently from standalone ㄷ.

How can I enter the raw ᆮ character?

Use Unicode code-point entry for raw ᆮ.

A Korean input method normally combines consonants and vowels into a finished syllable, so typing ㄷ usually enters a composing consonant rather than U+11AE by itself. Use a Unicode input method or an editor that accepts code points when you need the raw character.
