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.
Latvian language
The adoption of Latvian by minorities was brought about by its status as the only official language of the country, its prominence in the education system, its sole use in the public sector and by changes in the society after the fall of the Soviet Union that shifted linguistic focus away from Russian. As an example, in 2007 universities and colleges for the first time received applications from prospective students who had a bilingual secondary education in schools for minorities. Fluency in Latvian is expected in a variety of professions and careers.
