The article deals with several urbanonyms existing in the urban Polish language of Poznań and connected with Adam Mickiewicz Square and the two monuments located there: of Adam Mickiewicz and of the Poznań 1956 Protests. The material has been collected by means of a survey which was conducted among 100 Polish language students and 120 older persons (at the age of 35–85 years). The results of studies enabled scholars to observe a great onymic inventiveness of Poznań residents, constantly creating new, distinctly motivated urbanonyms, as well as a significant liveliness and an important role of those names in everyday linguistic communication of the city’s residents, and, consequently – in the regional variety of the Polish language.The article deals with several urbanonyms existing in the urban Polish language of Poznań and connected with Adam Mickiewicz Square and the two monuments located there: of Adam Mickiewicz and of the Poznań 1956 Protests.
