Hangul Syllable Ki

Alone it has several meanings; inside a word, context decides.

As a Korean word, 키 can mean a person’s height; a key or clue; a winnowing basket—a shallow tray for separating grain from husks—or a ship’s helm. In longer words such as 키보드 (“keyboard”) and 키우다 (“to raise or grow”), 키 is part of the whole word. Translate the complete word rather than this syllable by itself.

King Sejong devised Hangul for Korean because Chinese characters and earlier character-based writing could not represent Korean speech easily. Its creation is recorded in 1443; the 1446 book Hunminjeongeum explains its syllable pattern: an initial consonant, a vowel, and sometimes a final consonant. During the Joseon era, Hangul appeared in literature and private letters while official writing remained centered on Chinese characters. It was adopted for official documents in 1894, though Chinese text remained part of the transition. Some scholars propose that the older square ’Phags-pa script, made under Mongol rule for several languages, influenced Hangul; that link remains debated.

Why is 키 written as one block?

It joins one consonant and one vowel into a Korean syllable.

Here, ㅋ is the consonant, an aspirated “k” with a stronger puff of breath; ㅣ is the vowel, like “ee” in “see.” The letter design links ㅋ to the basic consonant ㄱ: adding a stroke to ㄱ marks the stronger aspirated sound.

How do I type 키?

Use a Korean two-set keyboard and type Z, then L.

With a Korean input method editor (IME) active, Z enters ㅋ and L enters ㅣ; the IME combines them as you type. In Windows Microsoft IME, right Alt toggles Korean and English input modes.

Unicode can store 키 as one precomposed block or as the two Hangul jamo (letter units) 키. These forms are canonically equivalent, so normalization lets software compare them consistently.
