The occurrence of the letters q and u together in English goes back to Latin, where they represented the \kw\ sound. In the Romance languages that descend from Latin, the qu combination is retained but in some of them (and especially French) it may represent just the \k\ sound, as in quiche. In the earliest written forms of English, the \kw\ sound was regularly spelled cw, as in a word like cwēn for a woman monarch or the wife of a king. Under the influence of Norman French spelling after the Conquest in 1066, however, cw was gradually replaced by qu. This change was essentially complete by the end of the 13th century, and several of our common words were affected by it: not only queen but also quick from Old English cwic and quake from Old English cwacian.
That aside, in this list q is not accompanied by u (except in a spelling variant). We hope we have cued our word game players to keep reading.
