The Central Caspian varieties spoken in Ramsar, Tonekabon, Kelardasht and surrounding areas of Mazanderan province are counted as part of the Mazandarani [mzn] languages in E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27/E28/E29. However, there is insufficient intelligibility between Central Caspian and other varieties of Mazandarani ( Borjian, Habib 2022: 8 , Donald L. Stilo 2018: 659-660 ) to justify this, and consequently, Central Caspian merits its own entry. See also: Mazanderani [mzn].
