Dialects
The Estonian dialects are divided into two groups – the northern and southern dialects, usually associated with the cities of Tallinn in the north and Tartu in the south, in addition to a distinct kirderanniku dialect, that of the northeastern coast of Estonia.
The northern group consists of the keskmurre or middle dialect that is also the basis for the standard language, the läänemurre or western dialect, roughly corresponding to Läänemaa and Pärnumaa, the saarte murre (islands') dialect of Saaremaa and Hiiumaa and the idamurre or eastern dialect on the northwestern shore of Lake Peipsi.
The southern group consists of the Tartu, Mulgi, Võru (Võro) and Setu (Seto) dialects. These are sometimes considered either variants of a South Estonian language, or separate languages altogether. Also, Seto and Võro distinguish themselves from each other less by language and more by their respective Christian confession.
