Toponymy and names

Warsaw's name in the Polish language is Warszawa. Other previous spellings of the name may have included: Warszewa, Warszowa, Worszewa or Werszewa. The exact origin and meaning of the name is uncertain and has not been fully determined. Originally, Warszawa was the name of a small fishing settlement on the banks of the Vistula river. One theory states that Warszawa means "belonging to Warsz", Warsz being a shortened form of the masculine Old Polish name Warcisław, which etymologically is linked with Wrocław. However the ending -awa is unusual for a large city; the names of Polish cities derived from personal names usually end in -ów/owo/ew/ewo (e.g. Piotrków, Adamów).

Folk etymology attributes the city name to Wars and Sawa. There are several versions of the legend with their appearance. According to one version, Sawa was a mermaid living in the Vistula with whom fisherman Wars fell in love. The official city name in full is miasto stołeczne Warszawa ("The Capital City of Warsaw").

A native or resident of Warsaw is known as a Varsovian – in Polish warszawiak, warszawianin (male), warszawianka (female), warszawiacy, and warszawianie (plural).
