In order to maintain the tradition of the solemn occasions used the name of the Capital City of Poznan [10] . Poznan as a center of political life is one of the first Polish cities, recorded in history. Because at that time Latin was the language used by the educated part of society, these are the records in the form of Latinized. The first known record is the chronicle of Thietmar the year 970 in the form of Episcopus Posnaniensis (Bishop of Poznań). At the same Chronicle under the year 1005 we find the definition of ab urbe Pošná (from the city of Poznan) [27] . The city in the form of Poznan noted Gall Anonim in his Polish Chronicle written in the years 1112-1116 [28] .

As nominativus Poznan appears in 1236 as Posnania and 1247 as Poznan . In addition, there are records from 1146 and 1244. In the form in Poznan , which allow the conclusion that the name of Poznan has not changed over the centuries.

Today, linguists agree that the name of Poznan is derived from the name of Poznan . It was created by adding a name to Poznan suffix j , which in times preliterate merged with the preceding it with the letter n softening it to the contemporary s .

While the explanation of the name does not pose a problem scientists, the very name of Poznan is not entirely clear. Historical sources do not provide information about the person whose name was given to the town on the Warta. It is also not clear whether this Slavic name derived from the verb " to know " belongs to the so-called. participial group names, such as Miłowan and runs , or is a shortened name dwuczłonowego example. Poznamir [29] .
