Hangul syllable 퀍

It spells a Korean syllable; the word or sentence supplies its meaning.

Its jamo—the consonant and vowel letters used to write Hangul—are ㅋ + ㅝ + ㅂ: an initial consonant, a vowel and a final consonant. Those parts show how the syllable is formed; they do not provide a word definition by themselves.

Hangul was created in Joseon to write Korean. The earliest documentary account of the system, Hunminjeongeum, dates to 1443; a book explaining its design and use appeared in 1446. The system first set out 28 letters that fit together to write Korean syllables. 퀍 is formed from those letters, not from a picture or a neighboring character.

Why can 퀍 appear as separate letters?

Unicode can store the syllable as one block or separate jamo.

Unicode normalization—a standard way to represent equivalent text—can store Hangul either as a precomposed block or as separate jamo. NFC keeps syllables composed; NFD separates them. A text field or font that handles the decomposed form may display the jamo apart.

A Korean input method composes letters as you type. When software exposes the decomposed form, the screen may show the pieces; this is a representation or display difference, not a different syllable.
