From Wikipedia, the free encyclopedia.
Q is the seventeenth letter of the Latin alphabet.
The Semitic sound value of Qôp was /q/. In Greek this sign (called Qoppa in Greek) probably came to represent several labial plosives, among them /k_w/ and /k_w_h/. These sounds changed to /p/ and /p_h/ respectively. Therefore, Qoppa was transformed into two letters: Qoppa, which stood for a number only, and Φι (Phi) which stood for the aspirated sound /p_h/ that came to be pronounced /f/ in Modern Greek. The Etruscans used Q only in conjunction with V, symbolizing thus a /k_w/. and V. Some scholars claim that Q and Phi are unrelated.
In most Modern Languages, Q is rather superfluous; in Romance and Germanic languages it usually appears followed by the letter u. In English this most often denotes the affricate /kw/, as it does in Italian; in German, /kv/; and in French, Spanish, and Catalan, /k/. (In Spanish, "qu" replaces c for /k/ before the vowels i and e, since in those contexts c is a fricative.). In Azeri, Uzbek, Tatar languages Q is pronounced the same as the Semitic sound q.
Quebec represents the letter Q in the NATO phonetic alphabet.
