In Czechia, over the span of two decades, we have witnessed an activity of creating new regions, regional institutions, and regional organization. This process has brought many new names to Czech toponymy.
The designation of a region is a unique symbol that fulfils a number of functions, including the identifying one, as the individual organizations can accept the identity of the region as their own via adopting its name. In this chapter, the attention will be paid to this aspect of the regional naming system.
The core of the research is to find out what phenomena serve as sources for names of new regional organizations. The chapter is also focused on the word-formation characteristics of the names and on the productivity of the -sko suffix.
