Baltic-Finnic refers to a group of languages within the Uralic language family, primarily spoken in the Baltic Sea region. This group includes languages such as Finnish, Estonian, and Karelian. These languages share common linguistic features and have historical connections, reflecting the cultural interactions among the peoples in this area. The Baltic-Finnic languages are characterized by their agglutinative structure, meaning they form words by stringing together various morphemes. They also exhibit vowel harmony, where vowels within a word harmonize to be either front or back vowels. This unique linguistic structure distinguishes them from the neighboring Indo-European languages.
