Latvian language
The Middle dialect is spoken in central and Southwestern Latvia. Kursenieki language, which used to be spoken along Curonian Spit, is closely related to the varieties of middle dialect spoken in Courland. The dialect is divided into the Vidzeme variety, the Curonian variety and the Semigallian variety. The Vidzeme variety and the Semigallian variety are closer to each other than to the Curonian variety, which is more archaic than the other two. There are three intonations in the Middle dialect. In the Semigallian variety, "ŗ" is still used. Standard Latvian is based on the middle dialect.
Baltic states
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.
