Hangul syllable regs

It is a Hangul syllable block built from three jamo. Hangul is the Korean alphabet; jamo are its letters, assembled into syllable blocks. 렋's canonical parts are ᄅ, ᅦ, and ᆪ: initial ㄹ, vowel ㅔ, and final cluster ㄳ. Unicode's label regs reflects those parts; it is not a Korean word or translation.

Hangul was designed as a Korean writing system that would be easier to learn and use. Before it, Korean was also written with Chinese characters and adaptations such as Idu, Gugyeol, and Hyangchal, which used Chinese characters in different ways to represent Korean. Hangul's development was completed in 1443; the Hunminjeongeum, a manuscript introducing and explaining the script, was published in 1446.

Hangul later appeared in royal letters, women's documents, religious texts, and everyday labels. It became Korea's official national writing system in 1894, then lost that status under Japanese rule in 1910. These dates describe the history of Hangul as a writing system.

How do I type and decompose 렋?

A Korean input method can compose it from its three jamo. Enter the initial ㄹ, vowel ㅔ, and final cluster ㄳ in a Korean input method editor (IME); it can combine them into the precomposed block 렋.

Unicode normalization can also expose the block as 렋. This is the canonical jamo sequence for the same syllable: NFC recomposes the block, while NFD exposes its components.
