Sigma
Sigma (upper case Σ, lower case σ, lower case in word-final position ς) is the eighteenth letter of the
Greek alphabet. In the system of
Greek numerals it has a value of 200. When used at the end of a word, and the word is not
upper case, the final form (ς) is used.The letter is ultimately derived from
Phoenician Sin . However, its name derives from
Samekh.In Eastern forms of Greek writing (as opposed to the
Western Greek alphabet used in the European Greek colonies) and in the Middle Ages, the
lunate sigma (upper case Ϲ, lower case ϲ) — which resembles, but which is not at all related to, the
Latin letter C — was often used. Lunate sigma was frequently used for writing
Medieval Greek, and it can still sometimes be seen in inscriptions in
Greek Orthodox churches, but also in certain printed editions of classical authors. The form of the
Cyrillic letter С [s] and
Coptic letter sima are derived from lunate sigma.
