Latvian language
Upper Latvian dialect is spoken in Eastern Latvia. It is set apart from rest of the Latvian by number of phonetic differences. The dialect has two main varieties – Selonian and Non-Selonian. There is a standard language, the Latgalian language, which is based on deep Non-Selonian varieties spoken in south of Latgale. The term "Latgalian" is sometimes also applied to all Non-Selonian varieties or even the whole dialect. However, it is unclear if it is accurate to use the term for any varieties besides the standard language. While the term may refer to varieties spoken in Latgale or by Latgalians, not all speakers identify as speaking Latgalian, for example, speakers of deep Non-Selonian varieties in Vidzeme explicitly deny speaking Latgalian.
Language policy in Latvia
The Electronic Mass Media Law orders to use only Latvian language in the first channels of public radio and television, and basically Latvian language in their second channels (Section 66).
The government of Latvia in its policy documents refers to Latvia as a (democratic) nation state, constructing societal integration on the basis of the Latvian language, while respecting the diversity of languages. Unity block, comprising most of the governing coalition as of 2011, also describes Latvia as a nation state. The idea of the nation state, where "language = nation", is seen as the core and main engine of the language policy of the Latvian state. Critics draw parallels between measures of the Latvian government and the assimilation of linguistic minorities in various countries.
