Eastern Indo-European refers to a branch of the Indo-European language family that includes languages primarily spoken in Eastern Europe and parts of Asia. This group encompasses languages such as Slavic, Baltic, and Indo-Iranian, which have evolved from a common ancestral language. The Eastern Indo-European languages share certain linguistic features and vocabulary, reflecting their historical connections. They are distinct from Western Indo-European languages, such as Germanic and Romance languages, which developed in different regions and cultural contexts. Understanding these languages helps linguists trace the migration and evolution of ancient peoples.
