On “historical unity” of Russian and Ukrainian: A linguistic perspective on language conflict and change

Abstract

This paper focuses on Putin’s (2021) misguided claim regarding “historical [linguistic] unity” of Russian and Ukrainian. Their being two distinct languages is not in question, as opposed (for example) to Serbian and Croatian. However, it is important to substantiate the objective reality of those differences, taking a strong stand against unjustified claims about linguistic [unity] where there are no grounds for them. Implementing a Python-coded algorithm, like those described in Nerbonne & Kretzschmar 2013, we calculate Levenshtein distance between frequency-based word lists, in a manner sensitive to both organic and contact-induced change, to fully reveal Ukrainian’s complex relationship with both Russian and Polish.
