Hangul syllable Ssyaep

On its own, 썦 gives too little context for a reliable reading.

It is a Korean Hangul syllable block made from a beginning consonant ㅆ, vowel ㅒ, and final consonant ㅍ. Syllable blocks combine into words, so the surrounding Korean word and sentence tell you what it means here.

The Korean writing system now called Hangul was announced under its original name 훈민정음 in 1443; an explanatory book followed in 1446. It was designed to write Korean speech by joining letters into syllable blocks. Earlier Korean labels included 정음, 언문, and 반절; after 1894, 국문 and 국서 also became common. The name Hangeul appears in records from the early 1910s and spread widely after 1928.

Why is 썦 one square?

One square groups Hangul letters into a syllable.

Here, ㅆ is the leading consonant, ㅒ the vowel, and ㅍ the final consonant. The block is precomposed, but text processing can also represent it as separate jamo—the individual Hangul letters. Hangul-aware text shapes that sequence as a syllable.

How do I type 썦 with a Korean keyboard?

On a Korean 2-set keyboard, type ㅆ, then ㅒ, then ㅍ.

The 2-set layout is the standard Korean keyboard arrangement, also called Dubeolsik. Its input software combines a leading consonant, vowel, and final consonant; Shift gives ㅆ and ㅒ on layouts where those forms share keys.
