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.
Livonian language
Livonian has for centuries been thoroughly influenced by Latvian in terms of grammar, phonology and word derivation etc. The dative case in Livonian, for example, is very unusual in a Finnic language. There are about 2,000 Latvian and 200 German loanwords in Livonian and most of the German words were adopted through Latvian. Latvian, however, was influenced by Livonian as well. Its regular syllable stress based on Livonian is very unusual in a Baltic language. In both languages the letter "h" is silent, unlike other Finnic and Baltic languages. Especially as of the end of the nineteenth century there was a great deal of contact with Estonians, namely between (Kurzeme) Livonian fishers or mariners and the Estonians from Saaremaa or other islands. Many inhabitants of the islands of Western Estonia worked in the summer in Kurzeme Livonian villages. As a result, a knowledge of Estonian spread among those Livonians and words of Estonian origin also came into Livonian. There are about 800 Estonian loanwords in Livonian, most of which were borrowed from the Saaremaa dialect.1st Article of the Universal Declaration of Human Rights
