William Rozycki's Mongol Elements in Manchu is a masterful work on the subject of Manchu and Mongolian linguistics. It identifies, analyzes, and categorizes occurrences of Mongol loan words in Manchu written documents in order to better understand the relationship between these two languages. In all, it examines 1,381 individual word correspondences and places them into eight individual categories: recent loans from Mongol to Manchu, early loans from Mongol to Manchu/Jurchen, ancient loans from Mongol to Tungus, pre-loan correspondences, loans from Manchu to Mongol, problematic cases, loans from Chinese to Mongol and Manchu, and dismissible cases. Both the linguistic analysis and comprehensive lexicon provide by this book make it an indispensable source for anyone studying or interested in the relationship between the Mongol and Manchu languages.
