Danko Šipka: Lexical layers of identity: words, meaning, and culture in the Slavic languages. Cambridge University Press, New York 2019, ISBN 978-953-313-086-6, S.166, doi:10.1017/9781108685795: „Lexical differences between the ethnic variants are extremely limited, even when compared with those between closely related Slavic languages (such as standard Czech and Slovak, Bulgarian and Macedonian), and grammatical differences are even less pronounced. More importantly, complete understanding between the ethnic variants of the standard language makes translation and second language teaching impossible.“
