Proper names are a relatively stable part of the cultural landscape and cultural traditions that were shaped for decades and centuries. They reflect cultural and social development, the development of spiritual culture, ethnic conditions and relations, language and dialects. This study addresses proper names as psycholinguistic and sociolinguistic elements whose formation and behavior are connected to the onymic space as well as its users. The author presents some circumstances affecting the common cultural values of proper names from the developmental aspect. The cultural and historical value of proper names is evaluated in relation to the objects motivating the names, and their significance to the name-givers. The language competencies of the society, and the modus operandi of proper names are also taken into account in the evaluation. Such values are reflected even in the current use of proper names and the relations of the community to them. The proper name represents the human connection to the place where an individual lives, it is an expression of this relationship and thus presents a peculiar anthropological phenomenon. It is important from the bottom-up perspective of users of the proper name within a regional onymic system. This study addresses the types of changes in oykonyms influenced by political and social changes and their impact on the social value of a proper name, its functions, motivational and communication potential of unofficial historical names. The author understands the proper name as part of tradition, culture and universal human heritage.
