Moravian dialects (Czech: moravská nářečí, moravština) are the varieties of Czech spoken in Moravia, a historical region in the southeast of the Czech Republic. There are more forms of the Czech language used in Moravia than in the rest of the Czech Republic. The main four groups of dialects are the Bohemian-Moravian group, the Central Moravian group, the Eastern Moravian group and the Lach (Silesian) group (which is also spoken in Czech Silesia).
