“…The structure and content of the concept of "frontier" has also undergone transformation. The phenomenon of the frontier is described in the works of domestic and foreign authors as a cultural and historical category (Ivanova, 2008), as a theme and approach to interpretation in literary discourse (Domansky, 2017;Markov, 2017), in political discourse (Benoist, 2016), the network frontier (Dovbysh, 2016), in sociological discourse -ethnocultural frontier (Grigorichev & Guzei, 2017), in the field of psycho-and ethno-linguistics (Krasnykh, 2002). However, as noted by Basalaeva (2012), there is still no clear definition of the frontier, its main constituent features and identification criteria have not been identified, which is the basis for considering the frontier as a discursive universal and as a discourse.…”
