Q (letter)
Q is the seventeenth letter of the English alphabet. Its name is pronounced like the words cue and queue.
Use in English
q has the same sound as k in kít and c in cát. It is almost always followed by a u, which is normally pronounced w. So qu = kw (kw itself is rare and accidental: åwkward). Examples (the accents show stress and pronunciation: see English phonemes for the IPA and English spellings for a table): quêen, quîet, quîte, quínce, quít, quíck, quêer, quâil, quáck, qùad, quŏrum, êqual, équity, aquátic, përquisíte, réquisíte, líquid. There is also the keyboard-describing word qwërty.
q is also used in transliterations from other languages to represent sounds not used in English, most commonly, to represent the sound of qaf in Arabic, and similar sounds in other Semitic languages and various Iranian languages including Persian. Thus q alone is used at the end of certain words from Arabic: Sádiq, Táriq, Iràq, and only in non-English words can it be doubled or otherwise appear minus the u: Sadíqqi, Qátar, Irāqi, níqab, qát stimulant (= cát animal).
In the pinyin system of transliterating Chinese, "q" is pronounced like "ch", as in Qíng Dýnasty (BrE), Qíng Dŷnasty (AmE).
In British English, qu can have an odd effect on a, like that of w in ẁas, making a sound like ó (shown here as qùa-): qùantity, qùarrel, qùality, eqùality (in American English, these are just quà-.). And, also as after w, it can go even further, as in quårtz (cf. wåltz).
Other vowels are not affected: quést, quêasy, quôte, inquîry or enquîry and neither is the a in quàrk, quáck.
The first u in queûe is redundant: queûe line = Keŵ Gardens = cûe prompt, billiards = the name of the letter Q.
The ending -que sounds like -k: BrE chéque money (= chéck verify, AmE money = Czéch nationality), unìque, bezìque, oblìque, clìque, opâque, mósque, Bāsque; cf. -gue: lêague, plâgue, also with silent -ue.
Other redundant us after q: líquor (*líkkə), píquèt (*pêekây), crôcquèt (*crôakây), Jácqueline (= Jácklin surname).
q does not begin clusters. qq appears only in some Arabic names; its normal ‘double’ is cq as in: acquîre, acquiésce.
