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.
Latvian language
Latvian belongs to the Baltic branch of the Indo-European language family. It is one of two living Baltic languages with an official status (the other being Lithuanian). The Latvian and Lithuanian languages have retained many features of the nominal morphology of the proto-language, though in matters of phonology and verbal morphology, they show many innovations, with Latvian being considerably more innovative than Lithuanian.
