Latgalian language
Latgalian is spoken in Latgale, the eastern part of Latvia. It is debated whether it is a separate language or a distinct dialect of Latvian. Nevertheless, its standardized form is recognized and protected as a "historical variety of the Latvian language" "(vēsturisks latviešu valodas paveids)" by Latvian law. The 2011 Latvian census established that 8.8% of Latvia's inhabitants, or 164,500 people, speak Latgalian daily. 97,600 of them live in Latgale, 29,400 in Riga and 14,400 in the Riga region.

The Estonian language is a Finnic language, together with neighboring Finland′s Finnish language.
Apart from the indigenous languages, German was the dominant language in Estonia and Latvia in academics, professional life, and upper society from the 13th century until World War I. Polish served a similar function in Lithuania. Numerous Swedish loanwords have made it into the Estonian language; it was under the Swedish rule that schools were established and education propagated in the 17th century. Swedish remains spoken in Estonia, particularly the Estonian Swedish dialect of the Estonian Swedes of northern Estonia and the islands (though many fled to Sweden as the Soviet Union invaded and re-occupied Estonia in 1944). There is also significant proficiency in Finnish in Estonia owing to its closeness to the native Estonian and also the widespread practice of listening to Finnish broadcasts during the Soviet era. Russian also achieved significant usage particularly in commerce.
