Hangul syllable Kyeolp

By itself, 켪 is a Hangul syllable block, not a word.

A Hangul block with ㄿ combines ㅋ as the initial consonant, ㅕ as the vowel, and ㄿ as a compound final cluster. Together they make one written Korean syllable; these parts show how a word is spelled, not a word to translate on their own.

Hangul's original name was Hunminjeongeum, roughly “correct sounds to teach the people.” It was created in 1443 to write Joseon Korean; its preface notes that Korean speech differed from Chinese. An explanatory book with the same name appeared in 1446. The name Hangeul is thought to appear in records from the beginning of the 1910s and became widely used after 1928. Those dates mark the script and its name, not this individual syllable.

How is ㄿ pronounced?

At a syllable's end, ㄿ becomes one p-like closing sound.

In standard Korean, final ㄿ is realized as ㅂ: the lips close to stop the sound, without an extra vowel. In 읊다, the following ㄷ becomes tense. The full word sets the pronunciation; ㄹ and ㅍ are not two separate endings here.
