S̩ (minuscule: s̩) is a letter of the Latin alphabet, formed from S with the addition of a vertical line below it. It is used in Yoruba to represent the sound [ʃ] (like English "sh").

The line is sometimes replaced by a dot, i.e. Ṣ ṣ.

[s̩] is also the International Phonetic Alphabet symbol for a syllabic "s" sound.

Computer encoding

• S̩: U+0053 S LATIN CAPITAL LETTER S + U+0329 ̩ COMBINING VERTICAL LINE BELOW
• s̩: U+0073 s LATIN SMALL LETTER S + U+0329 ̩ COMBINING VERTICAL LINE BELOW
