The Semitic sound value of Qôp was q , a sound common to Semitic languages, but not found in English or most Indo-European ones. In Greek, this sign as Qoppa Ï probably came to represent several labialized velar stops, among them kÊ· and kÊ·Ê° . As a result of later sound shifts, these sounds in Greek changed to p and pÊ° respectively. Therefore, Qoppa was transformed into two letters: Qoppa, which stood for a number only, and Phi Φ which stood for the aspirated sound pÊ° that came to be pronounced f in Modern Greek.
