How did Polish literary language change during the Renaissance?

During the Renaissance, the Polish language underwent a significant transformation, evolving from a secondary medium into a sophisticated tool for literary expression. While early Polish literature was dominated by Latin, the 16th century marked the emergence of a modern literary language based on dialects from the region around Poznań.2

Key developments during this period included:

• Shift to the Vernacular: Although initial Renaissance writers in Poland primarily used Latin, influential figures began championing the native tongue. Mikołaj Rej, often called the father of Polish literature, was the first to demonstrate the potential of idiomatic Polish in his prose and satirical works.1
• Standardization and Innovation: The humanist poet Jan Kochanowski played a pivotal role by devising new poetic syntax and patterns of versification. By modeling his work on classical traditions, he elevated the elegance and precision of the Polish language.2
• Expansion of Literary Forms: The period saw the production of diverse works, including political treatises, didactic dialogues, and translations of the Bible, such as the notable version by Jakub Wujek.3

By the end of the Renaissance, these efforts successfully established Polish as a national literary language.3
