How are Russian, Ukrainian, and Belarusian related?

Russian, Ukrainian, and Belarusian constitute the East Slavic language group, a branch of the Indo-European family. These languages are closely related, sharing historical roots and linguistic features that reflect their shared development.123

Belarusian serves as a linguistic link between Russian and Ukrainian. Its dialects shade gradually into those of its neighbors, with some features transitioning toward Russian and others toward Ukrainian. While each language has developed its own literary standard—often based on specific regional dialects, such as those of Moscow, Kyiv, or Minsk—they all utilize the Cyrillic alphabet.431

Historically, these languages have been shaped by varying degrees of contact with other cultures, such as the influence of Polish on Belarusian, and the administrative use of older forms of Belarusian in the Grand Duchy of Lithuania. Despite their close relationship, each has evolved into a distinct language that serves as a central component of national identity for its respective speakers.435
