Q is the seventeenth letter of the Latin alphabet. Its name in English is cue, occasionally spelled cu.
The Semitic sound value of Qôp (perhaps originally qaw cord) was /q/ (voiceless uvular plosive). In Greek this sign as Qoppa Ϙ probably came to represent several labialized velar plosives, among them /kʷ/ and /kʷʰ/. These sounds changed to /p/ and /pʰ/ respectively. Therefore, Qoppa was transformed into two letters: Qoppa, which stood for a number only, and Phi Φ which stood for the aspirated sound /pʰ/ that came to be pronounced /f/ in Modern Greek. The Etruscans used Q only in conjunction with V, symbolizing thus a /kʷ/. Some scholars claim that Q and Phi are unrelated.
Usage
In most modern languages, Q is rather superfluous; in Romance and Germanic languages it appears almost exclusively in the digraph QU. 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 and in French, qu replaces c for /k/ before the vowels i and e, since in those contexts c is a fricative.) In the Aymara, Azeri, Uzbek, Quechua, and Tatar languages, Q is a voiceless uvular plosive. q is also used in IPA for the voiceless uvular plosive, as well as in most transliteration schemes of Semitic languages for the "emphatic" qōp sound.
In Maltese and Võro, Q denotes the glottal stop.
In Chinese Hanyu Pinyin, Q is used to represent the sound [tɕʰ], which is similar to English "ch" in "cheese".
