Hangul Syllable Nud

On its own, 눋 is a syllable fragment, not a complete word.

In Korean, it appears in 눋다, “to become slightly scorched,” especially of rice or other food.

Hangul was created in 1443 and promulgated in 1446 so more people could learn to read and write. Its letters stack into syllable blocks, a compact layout historically influenced by Chinese-character writing.

Why does 눋 become 눌어?

The final consonant changes with the verb’s ending.

눋다 keeps ㄷ before consonant-starting endings, as in 눋고 and 눋지, but changes to ㄹ before the vowel-starting ending -어, producing 눌어. The established spelling is 눌어붙다; 눌러붙다 is incorrect. The compound can also describe someone who sticks around and refuses to leave.

The food word 누룽지, for the crust of scorched rice, appears in 19th-century records and is analyzed as 눋다 plus the word-forming parts -웅 and -지. That date belongs to the food word, not the isolated syllable 눋.
