Ṣ
Ṣ (minuscule: ṣ) is a letter of the Latin alphabet, formed from an S with the addition of a dot below the letter. == Usage == The uses of Ṣ include: the romanization of Semitic languages to represent an "emphatic s" /sˤ/, such as the Arabic ص (ṣād) or sometimes the Hebrew צ (tzadi) as pronounced by Mizrahi Jews; the romanization of Indic languages to represent retroflex /ʂ/; the orthography of Yoruba in Nigeria to represent the voiceless palato-alveolar sibilant /ʃ/ (the English "sh" sound); the Alvarez-Hale orthography of the Tohono Oʼodham language for retroflex /ʂ/ (Akimel O'odham and Saxton use ⟨sh⟩ instead).
