Historical Sources as the Material for Carrying out Regional Dialеct Research (on the Material of the Ardennes and Champagne Regional Dialects)
The article deals with the problem of the use of historical works to study the Ardennes and Champagne variants of the French language. It pays particular attention to a variety of periodic historiographic publications that serve as a source for collecting linguistic facts, clarifying the areal characteristics of the regionalisms, describing the anthroponymic system of marked ususes, and conducting a field experiment. The data of the analyzed sources can be used to recreate regional dialect receptive concepts and to define the specifics of the regional dialect as an «intangible cultural heritage».
