shin

Shin (also spelled Šin (šīn) or Sheen) is the twenty-first letter of the Semitic abjads, including Phoenician šīn 𐤔, Hebrew šīn ש, Aramaic šīn 𐡔, Syriac šīn ܫ, and Arabic sīn س . Its sound value is a voiceless sibilant, [ʃ] or .
The Phoenician letter gave rise to the Greek Sigma (Σ) (which in turn gave Latin S and Cyrillic С), and the letter Sha in the Glagolitic and Cyrillic scripts (, Ш).
The South Arabian and Ethiopian letter Śawt is also cognate.
