The letter Q has always intrigued people. Words like 'bouquet', 'acquiesce' and 'quinquennial' seem to have an almost mystical quality. Formists struggle to include Q in pyramids and squares while pangrammatists always find it the most difficult letter to incorporate into their compositions. Of course the main problem is that the letter Q is almost invariably followed by a U (for exceptions, see the editor's article in the May 1976 Word Ways). This constraint has severely limited the scope of Q in most fields of wordplay, although there are some ingenious examples of its use, such as the amazing forms of Palmer Peterson exhibited in the May 1978 Word Ways.
