Abstract: The subject of the study is the characteristic of the morphemic composition of adverbs in the Russian dialects of the Amur region, characterized by secondary formation and localization in the territory of late settlement. In this work, the author analyzes the study of the structure of adverbs in the Russian literary language and refers to the experience of studying this part of speech in Russian dialectology. The novelty of this study lies in the fact that the adverbial lexeme in the studied group of dialects in the structural aspect has not been previously considered by scientists. For the first time, using the methods of continuous sampling, descriptive-analytical and comparative analysis, an attempt was made to classify the adverbs recorded in the second edition of the Dictionary of Russian Dialects of the Amur Region. The material allowed to distribute the selected adverbs into 10 groups. The observations have shown that the main problems in studying the structure of adverbs in this group of dialects are the ratio in their characteristics of all-Russian features and locally limited, the articulability of adverbs of individual groups, as well as the preservation of some relics that make it possible to trace the dynamics of the vernacular vocabulary. The relevance of the work is due to the fact that the study of this group of linguistic units is necessary to build a typology of dialects of the Amur Region, monograph their description, identify the features of the language in the aspect of its regional existence and recreate the structure of the Russian dialect space as a whole.
