Hangul syllable ddeolh

Alone, 떯 has no fixed word meaning; 떯다 can mean “pierce.” The September 2026 dialect entry lists 떯다 as a regional form of standard Korean 뚫다 (“to pierce a hole”), reported in Gimje, Buan and Hampyeong. Its evidence is about the full verb, not 떯 by itself, so a lone syllable needs the surrounding word.

Hangul was devised for writing Korean: its creation is dated to 1443, and the 1446 Hunminjeongeum, an explanatory book, describes how consonants and vowels fit into syllable blocks. Those dates belong to the writing system, not to a proven first appearance of 떯.

Why does 떯 look like a whole block?

It combines a starting consonant, vowel, and final consonant cluster. The written parts are ㄸ, ㅓ and ㅀ. The spelling shows how the block is built; it does not guarantee how 떯 would sound in isolation.

Korean text can represent a syllable as one precomposed character or as its sequence of jamo, the letters used to build Hangul syllables. A capable input method can join the jamo into a block, and fonts can draw that block differently without changing its written parts.
