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.
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.
