📙 It so happened that I had graduated from educational institutions in 1976 for the first time 1986 and in 2006.Accordingly, it is Leningrad Arctic school (specialty - technician-aerologist), Gorky state University named after N. Lobachevsky (philologist); Orthodox St. Tikhon theological Institute (now - University for the Humanities; an expert of theology).This book is written based on my thesis at the end of the GSU, where I majored in the Department of history of Russian language and comparative Slavic linguistics.
