Xxxx \ ʒʒʒʒ \ n: any word that rhymes with the word in question
For example, a xish means or refers to any word that rhymes with fish. Dish is a xish, for example, as are swish and Gish. Telephone is a xelephone. Shoe is a xhoe where through is a xough, but bough is a xough, and cow, of course, is a xow. All xxxxs (e.g. xish, xelephone, etc.) start with ‘X,’ which ‘X’ is pronounced ‘ʒ,’ i.e. a voiced palato-alveolar fricative, e.g. the ‘S’ in Asia or casual. Casual is a xasual, which is fun. Gearbox is a xerox* (NB the lower-cased ‘X’ (Xerox is also a xerox)), and if there were such a thing as a xenophobia aside from xenophobia, it would look the same in print and/or on screen as xenophobia, but would be pronounced differently. Xxxx is spelled with four ‘X’s to avoid confusion with xxx, which has connotations. As far as pronunciation goes, the duration or extension of the ʒ is sort of up to the speaker.
*A near-xerox, actually.
