|Egyptian hieroglyph wj||Phoenician Q||Etruscan Q||Greek Qoppa|
The Semitic sound value of Qôp (perhaps originally qaw cord of wool, and possibly based on an Egyptian hieroglyph) was /q/ (voiceless uvular plosive), a sound common to Semitic languages, but not found in English or most Indo-European ones. In Greek, this sign as Qoppa Ϙ probably came to represent several labialized velar plosives, among them /kʷ/ and /kʷʰ/. As a result of later sound shifts, these sounds in Greek 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 to represent /kʷ/.
In the Aymara, Greenlandic, Uzbek, Quechua, and Tatar languages, as well as romanised Arabic, Q is a voiceless uvular plosive. [q] is also used in the IPA for the voiceless uvular plosive, as well as in most transliteration schemes of Semitic languages for the "emphatic" qōp sound. The sound is rendered with letter ﻕ in Arabic script.
In Kiowa, Q represents a glottalized velar plosive, /kʼ/.
Q, which is rarely seen in a word without a U next to it in English, is the second most rarely used letter in the English language. The Q represents a voiceless velar plosive, contrary to the belief that it represents a labialized voiceless velar plosive. If this were the case, there would be no need for the "U" at the end.
The lowercase Q is usually written as a lowercase O with a line below it, with or without a "tail". It is usually typed without due to the major difference between the tails of the lowercase G and lowercase Q. It is usually written with the tail to distinguish from the G. Unlike the written lowercase G, which has a leftward facing tail, the Q's tail faces right. An example of the lowercase Q written from a keyboard is a "q".
The EBCDIC code for capital Q is 216 and for lowercase q is 152.
