Altaicization and De-Altaicization of Japonic and Koreanic

What is it about?

This study examines the grammar of Japanese, Korean, and their related languages in comparison to other Northeast Asian languages. Researchers used a computer tool to analyze both modern and older versions of these languages, finding that Japanese and Korean share a bunch of grammatical features (up to 26!) that make them different from other regional language groups. Interestingly, historical records suggest that Japanese and Korean became more similar to each other (and other regional languages that share features of the Altaic family) but later evolved to be more distinct. This research tells us about changing patterns of language contact and influence in Northeast Asia across time.

Why is it important?

This work is important because it traces the historical connections and divergences between Japanese, Korean, and other Northeast Asian languages. By examining the changes in grammar over time, researchers can understand the complex influences these languages have had on each other and the broader linguistic landscape of the region. This research gives us a clearer picture of the intricate relationships between languages, showing how historical contact and interaction leave lasting impacts on how languages evolve and change.
