Gamma

Gamma (uppercase Γ, lowercase γ) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. It was derived from the Phoenician letter Gimel Gimel. Letters that arose from Gamma include the Roman C and G and the Cyrillic letters Ge Г and Ghe Ґ. In Modern Greek, it represents either a voiced velar fricative /ɣ/ or a voiced palatal fricative /ʝ/. In Ancient Greek, it represented a voiced velar stop /ɡ/. Before velars, it represents a velar nasal /ŋ/ in Modern as well as Ancient Greek, and a double gamma represents a prenasalized voiced velar stop (/ŋɡ/).
