Linguists today distinguish four different dialects, which are not all mutually intelligible: Hill Mari (мары йӹлмӹ), concentrated mainly along the right Volga bank; Meadow Mari (марий йылме), spoken in the lowland regions of the Kokshaga and Volga rivers, which includes the city of Yoshkar-Ola; Eastern Mari, spoken east of the Vyatka River; and Northwestern Mari (маре йӹлмӹ) in the South-West of Kirov Oblast and North-East of Nizhny Novgorod Oblast.
