The article offers a survey of works of Ukrainian linguists in the field of Church Slavonic, in particular its Ukrainian recension. While applying the historiographic approach, the author focuses on various publications and the study of the language of some records and their authors, and the reconstruction of orthoepy. The article also discusses some controversial questions of the interrelation between the Ukrainian (southern) and the Great Russian (northern) redaction of the Church Slavonic language from the second half of the 17th century onward. The author also highlights changes in the methodological principles and argues that, despite the use of sociolinguistic and cognitive methods along with the traditional structural and functional approach, the current discourse in Ukrainian linguistics appears to be incomplete.
