Hangul syllable Ruj

By itself, 룾 has no fixed meaning as a Korean word.

In the Unicode name, “Ruj” labels the syllable’s sound sequence; it is not a Korean translation. The block combines three jamo—letters that form Hangul syllables: initial consonant ᄅ, vowel ᅮ, and final consonant ᆽ. The surrounding Korean word supplies its meaning.

Hangul was devised as a practical, learnable writing system for Korean. Its creation was recorded in 1443, and it was introduced in the document Hunminjeongeum, published in 1446. It offered a direct way to write Korean alongside older practices such as Idu, which used Chinese characters to write Korean. Hangul spread through translations, manuals, primers, and literature. In 1894, the Joseon government made Korean script the basis of official documents, while mixed Korean-and-Hanja writing continued.

How do I type 룾?

Use a Korean IME and enter the three parts in order.

In a Korean IME (input method), enter the initial consonant ㄹ, vowel ㅜ, then final consonant ㅈ; it assembles them as 룾. Unicode also represents the same syllable with the decomposed sequence 룾. NFC, Unicode’s composed normalization form, combines the jamo into one block; NFD, its decomposed form, expands the block to the three jamo.

Fonts choose the placement, shape, and size of the jamo inside the block, so 룾 can look different across typefaces without becoming a different character. The bottom component is its final consonant, not decoration.
