Hangul syllable ggyi

It writes ㄲ + ㅢ as one Hangul syllable.

ㄲ is the firmly articulated, tense version of ㄱ; ㅢ combines ㅡ and ㅣ. In standard Korean, ㅢ after an initial consonant is pronounced like ㅣ, the “ee” in “see,” so 끠 can sound like 끼 even though the spelling differs.

Hangul was devised in 1443; the 1446 Hunminjeongeum manuscript explained the new script and how it represented Korean. 끠 follows that system’s design: letters combine into syllable blocks.

How do I type 끠?

Use Korean 2-set input: Shift+R, then M, then L.

In Dubeolsik, Shift+R gives ㄲ, M gives ㅡ, and L gives ㅣ. A Korean IME joins the two vowels as ㅢ and forms the block; switch to Korean input first.

If the app leaves the jamo separate, it may be showing a decomposed form rather than losing the key sequence.

Why can 끠 look broken?

A font or app may show the component jamo separately.

Unicode can represent this syllable as a precomposed block or as the conjoining-jamo sequence 끠. Some font and app combinations do not shape that sequence into one block, so separate-looking parts can still encode the same syllable.

뀌 is a different syllable: its vowel is ㅟ, while 끠 has ㅢ. 끼 is closer in sound under the Korean pronunciation rule, but its spelling uses ㅣ.
