Estonian language:

The southern group (South Estonian language) 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 culture and their respective Christian confession.
