Hangul syllable Nweog

Use a Korean input method with Dubeolsik: type snjr. On Dubeolsik, s enters ㄴ, n enters ㅜ, j enters ㅓ, and r enters ㄱ. The input method combines ㅜ + ㅓ into ㅝ, then joins the letters as 눡. Typing the romanized label nweog on a Latin keyboard enters letters, not this Hangul syllable.

What does 눡 mean?

It represents a syllable; its word-level meaning depends on context.

Hangul letters, called jamo, fit into blocks for a syllable: an opening consonant, a vowel, and sometimes a closing consonant. Here ㄴ opens the syllable, ㅝ is the vowel, and ㄱ closes it. Unicode's decomposed sequence, ᄂ + ᅯ + ᆨ, writes those same parts separately.

Hangul was designed to write Korean and make its sounds teachable. Its first recorded announcement was in 1443; the explanatory book Hunminjeongeum was published in 1446 to explain the script's purpose, letter design, and syllable assembly. Earlier names included Hunminjeongeum, jeongeum, eonmun, and gukmun. “Hangeul” spread from the early 1910s and became widely used as the public holiday's name in 1928.

What does it mean if someone sends 눡?

By itself, it does not reveal a word-level meaning. Ask what word or sentence it belongs to. Inside a Korean word or sentence, its sound and role come from that surrounding text.
