Q
From Wikinfo
Q is the 17th letter of the Latin alphabet.
The Semiit sound value of Q�p 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 digraph most often denotes the cluster /kw/, as it does in Italian (where [w] is an allophone of /u/); 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 the Azeri, Uzbek, and Tatar languages, Q is pronounced the same as the Semitic sound q.
Quebec represents the letter Q in the NATO phonetic alphabet.
