jazzes

1. 1
   verb

   Third-person singular simple present of jazz.

   The decorator jazzes up the lobby with fresh flowers every Monday morning.

   He jazzes up his lectures with vivid stories and surprising examples.

   Note

   The -es ending is the one English adds after a hissing sound, so jazz becomes jazzes just as buzz becomes buzzes. It goes with he, she, it or a singular noun, as in the band jazzes and the decorator jazzes the lobby. Most present-day uses carry the brightening sense. The slang senses of ruining or complicating are informal, and a dated American sense of selling sex makes context worth checking.

2. 2
   noun

   Plural of jazz.

   The compilation traces how regional jazzes diverged across the early twentieth century.

   Critics debate whether these jazzes share enough to sit under one label.

   Note

   A plural the noun mostly does without, because in every sense jazz is usually uncountable. Jazzes appears chiefly when styles or traditions are set against one another, as in regional jazzes or the jazzes of different decades. For energy, nonsense or the stuff a thing is made of, English keeps the singular. The spelling follows the same pattern as the verb form.
