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
Articles 4 and 114 of the Constitution of Latvia form the foundation for language policy in Latvia, declaring Latvian to be the official state language and affirming the rights of ethnic minorities to preserve and develop their languages. Livonian language is recognized as "the language of the indigenous (autochthon) population" in the Official Language Law, but Latgalian written language is protected as "a historic variant of the Latvian language." All other languages are considered foreign by the law on state languages. Latvia provides national minority education programmes in Russian (the first language for more than one third of the population), Polish, Hebrew, Ukrainian, Estonian, Lithuanian, and Belarussian.
