Wikipedia definition:
Sigma (/ËsɪɡmÉ/ SIG-mÉ;1 uppercase Σ, lowercase Ï, lowercase in word-final position Ï; Greek: Ïίγμα) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator for summation. When used at the end of a letter-case word (one that does not use all caps), the final form (Ï) is used. In á½Î´Ï
ÏÏεÏÏ (Odysseus), for example, the two lowercase sigmas (Ï) in the center of the name are distinct from the word-final sigma (Ï) at the end. The Latin letter S derives from sigma while the Cyrillic letter Es derives from a lunate form of this letter.
