Предыстория древнерусского термина «бо(л)ярин»
In the article the author analyses the semantics of the word bo(l)jarin in the texts in Old Slavonic and Church Slavonic dating back to the 10-11th centuries. The author concludes that the word denoted a noble person who owed his upper status not to moral authority or local (tribal) background but to possession of political power and offices. This conclusion gives a context to understand the meanings of the word in the Old Russian sources of the 11th century. There are no obstacles to think that the main meaning was the same as in the Old and Church Slavonic texts.
