Hangul syllable Ceb

It is a syllable, not a complete word.

Hangul is the Korean alphabet; its letters, called jamo, combine into square syllable blocks. 쳅 combines initial ㅊ, vowel ㅔ, and final ㅂ, roughly like “chep”; the final ㅂ ends with the lips closed for p, without releasing a burst of air. Unicode’s technical label “Ceb” describes this component sequence; it is not a Korean word.

When did Hangul begin?

Hangul’s earliest documented record dates to 1443.

A book called Hunminjeongeum, published in 1446, explained Hangul’s letters and how they combine into syllables with an opening consonant, a vowel, and sometimes a final consonant. The system was devised to make Korean easier to write and learn without relying on Chinese characters.

Names for the writing system included eonmun (“vernacular writing”), gukmun (“national script”), and gukseo (“national writing”); Hangeul became a common name in the early 1910s. These dates concern Hangul as a writing system, not when this particular syllable was first written.
