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.

It proposed several constitutional amendments for introducing Russian as Latvia's second official language—i.e., amendments to the Satversme’s Articles 4 (on Latvian as the state language), 18 (on the solemn promise of a member of Parliament to strengthen the Latvian language), 21 (on Latvian as the working language of the Parliament), 101 (on Latvian as the working language of local governments), and 104 (on the right to receive a reply to a petition in Latvian). Obviously, the proposed amendments would have influenced other constitutional norms as well. Moreover, since Article 4 of the Satversme alike norms of independence, democracy, sovereignty, territorial wholeness, and basic principles of elections that form the core of the Satversme (according to Article 77 of the Satversme), the initiative, in fact, proposed discontinuing an existing state and establishing a new one that is no longer a nation-state wherein Latvians exercise their rights to self-determination, enjoying and maintaining their cultural uniqueness
