Hangul syllable ceoj

Three jamo (Hangul letters): initial ㅊ, vowel ㅓ, and final ㅈ.

Hangul’s creation is recorded in 1443, during King Sejong’s reign. A guide to the script, Hunminjeongeum, was published in 1446. Hangul was designed to make Korean easier to write and learn than the Chinese-character-based writing tools then in use. Today’s Korean spelling system is based on a unified-orthography draft from 1933.

A 2019 study compares Hangul’s syllable-block design with the Phags-pa script. That is a comparison of writing-system design, not evidence that this individual syllable was borrowed.

How do you pronounce 첮?

An aspirated ㅊ, vowel ㅓ, then final ㅈ.

The opening ㅊ sounds like the “ch” in “church,” with a stronger puff of air. The vowel ㅓ is close to the vowel in “sun,” though no English match is exact. The final ㅈ is batchim—the bottom consonant; at a word end or before another consonant it becomes a t-like stop with no audible release, while before a vowel it links into the next syllable.
