Su (kana)

Character of the Japanese writing system

Su (hiragana: す, katakana: ス) is one of the Japanese kana, each of which represents one mora. Their shapes come from the kanji 寸 and 須, respectively. Both kana represent the sound [sɯ]. In the Ainu language, the katakana ス can be written as small ㇲ to represent a final s and is used to emphasize the pronunciation of [s] rather than the normal [ɕ] (represented in Ainu as ㇱ). In loanwords, this dakuten form of this kana, as opposed to 's dakuten form, can be used when transliterating "ds" such as kids キッズ kizzu and birds ば, っず.
