New reading vocabulary descriptions

The work on the multi-volume Dictionary of the Russian Language of the 11^th-17^th centuries and the preparation and publication of which lasts decades, inevitably entails a revision of the published material, the appearance of additions, as well as correction of errors and inaccuracies (addenda et corrigenda). The author considers the few words with the Slavic root твор- and on the basis of etymological and lexicological analysis comes to the conclusion about the need to clarify the 18^th meaning of the verb творити, which should be formulated differently: ‘to harm’. In the second study, the author establishes the origin and meaning of the lexeme опсимъ. The lack of information about it is evidenced by the question mark in this Dictionary. The word comes from the Greek ἀψίνθιον, ἀψίνθιος, ἄψινθος ‘wormwood (bitter) wine’, and discovered in the Slavic translation of the 13^th century shapes асфинфъ and ѥспинфъ still not been described yet neither in paleo- and media-Slavic, nor in Russian historical lexicography.
