Hangul syllable Ilm

읾 is a Korean syllable block; the surrounding word gives it meaning.

읾 is built from the Hangul jamo (letters) ᄋ + ᅵ + ᆱ: initial ㅇ, vowel ㅣ, and final cluster ㄻ. The Unicode label “Ilm” describes this written assembly rather than giving the block a separate definition.

Hangul’s history is older and broader than this syllable. The National Hangeul Museum dates its first recorded mention in the Sejong Annals to 1443 and the explanatory book Hunminjeongeum to 1446. Created to write speech in Joseon, the Korean kingdom of that period, Hangul spells syllables by assembling initial, vowel, and final sounds.

How do I type 읾?

A Korean keyboard can form it from its jamo keys.

With a Korean input method set to Hangul, enter ㅇ, ㅣ, ㄹ, then ㅁ. The input method combines the final ㄹ and ㅁ into ㄻ and composes one syllable block. The precomposed character 읾 and the sequence 읾 represent the same structure but are different Unicode sequences until normalization.

Why do my Hangul jamo stay separate?

It may be decomposed text or missing Hangul shaping support.

Unicode distinguishes precomposed Hangul syllables from conjoining jamo, the letter forms used to assemble a syllable. Fonts and text engines shape supported sequences into blocks; a decomposed or incomplete sequence may remain separate.
