In general, Hokkien dialects have 5 to 7 phonemic tones. According to the traditional Chinese system, however, there are 7 to 9 "tones",[citation needed] more correctly termed tone classes since two of them are non-phonemic "entering tones" (see the discussion on Chinese tone). Tone sandhi is extensive. There are minor variations between the Quanzhou and Zhangzhou tone systems. Taiwanese tones follow the patterns of Amoy or Quanzhou, depending on the area of Taiwan. Many dialects have an additional phonemic tone ("tone 9" according to the traditional reckoning), used only in special or foreign loan words.
