Hangul syllable ulp

욾 is one Hangul syllable block; its word supplies the meaning.

Its jamo are initial ㅇ, vowel ㅜ, and final ㄿ. That final consonant cluster is the batchim, the consonant position at the end of a syllable. The label “ulp” describes the block’s spelling; it does not translate it. If the parts appear separately as ㅇㅜㄹㅍ, the input method has left the jamo uncomposed, so you are not seeing the same precomposed block.

Why are Hangul letters arranged in blocks?

Hangul groups letters into blocks to write Korean syllables. The first recorded creation notice dates to 1443, and an explanatory book about the script appeared in 1446. Hangul offered a writing system designed around Korean speech, rather than requiring readers to use Chinese characters.

Before Hangul, Korean writing used Chinese characters in systems such as Idu, Hyangchal, and Gugyeol, which adapted them to write Korean. Hangul later appeared alongside Hanja—the Chinese characters used in Korean writing—in books and public documents, before Hangul-only writing became more common. Jamo are its building blocks; movable type, typewriters, and digital fonts kept the block layout while varying the proportions and positions of those parts.
