| Footnote: | These Man'yōgana originally represented morae with one of two different vowel sounds, which merged in later pronunciation. |
き, in hiragana, キ in katakana, is one of the Japanese kana, which each represent one mora. Both represent pronounced as /[ki]/ and are derived from a simplification of the Japanese: [[wikt:幾|幾]] kanji. The hiragana character き, like さ, is drawn with the lower line either connected or disconnected.
A dakuten may be added to the character; this transforms it into ぎ in hiragana, ギ in katakana, and gi in Hepburn romanization. The phonetic value also changes, to pronounced as /[ɡi]/ in initial, and varying between pronounced as /[ŋi]/ and pronounced as /[ɣi]/ in the middle of words.
A handakuten (゜) does not occur with ki in normal Japanese text, but it may be used by linguists to indicate a nasal pronunciation pronounced as /[ŋi]/.
