す, in hiragana or ス in katakana, 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).^[1]
