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 [su͍]). 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).
