The Polish the name of a county, in the administrative sense, consists of the word "powiat" followed by a masculine-gender adjective (because "powiat" is a masculine noun). In most cases, this is the adjective formed from the name of the town or city where the county has its seat. Thus the county with its seat at the town of Kutno is named "powiat kutnowski" (Kutno County). (In modern Polish both parts of the name are written in lower case; however, names of powiats in the Grand Duchy of Poznań were written in upper case.) If the name of the seat comprises a noun followed by an adjective, as in Maków Mazowiecki ("Mazovian Maków"), the adjective will generally be formed from the noun only ("powiat makowski"). There are also a few counties whose names are derived from the names of two towns (such as "powiat czarnkowsko-trzcianecki", Czarnków-Trzcianka County), from the name of a city and a geographical adjective ("powiat łódzki wschodni", Łódź East County), or a mountain range ("powiat tatrzański", Tatra County).
