Hangul syllable Nulh

It is one Hangul syllable, not a complete word.

Hangul is the Korean writing system; its letters, called jamo, combine into square-shaped syllable blocks. 눓 contains ᄂ (initial n), ᅮ (vowel ㅜ), and ᆶ (final cluster ㅀ). The label “Nulh” identifies the components; it is not a translation.

Inside a Korean word, pronunciation depends on what follows. Before a vowel, ㅎ drops and ㄹ links across, as in 싫어 and 닳아; before some consonants, ㅎ can make the next sound breathier. The spelling shows the syllable, while the full word tells you how to say it.

Hangul was devised under King Sejong in 1443; in 1446, Hunminjeongeum, a book about the script, explained its purpose and design. It aimed to make Korean easier to write and learn. Hangul became Korea's national writing system in 1894, lost that status under Japanese rule in 1910, and new spelling policies followed after 1945. These are milestones in Hangul's history, not a separate history for 눓.

How do I type 눓?

Type its jamo; a Korean input method builds the block.

Dubeolsik is the standard Korean 2-Set keyboard layout. Switch your input method to Korean and type the keys s n f g in order (ㄴ + ㅜ + ㄹ + ㅎ). The input method combines the last two consonants into ㅀ and produces 눓.

Unicode's canonical decomposition of this syllable is ᄂ + ᅮ + ᆶ. An input method that accepts that sequence can compose the same block. If the jamo appear separately, you are seeing the decomposed spelling; fonts can shape it differently without changing the character.
