Warsaw is one of Europe's most dynamic metropolitan cities. In 2012 the Economist Intelligence Unit ranked Warsaw as the 32nd most liveable city in the world. In 2017 the city came 4th in the "Business-friendly" category and 8th in "Human capital and life style". It was also ranked as one of the most liveable cities in Central and Eastern Europe.
Warsaw's name in the Polish language is Warszawa (also formerly spelled Warszewa and Warszowa). Other previous spellings of the name may have included Worszewa and Werszewa. According to some sources, the origin of the name is unknown. In Pre-Slavic toponomastic layer of Northern Mazovia: corrections and addenda (the Narew drainage), it is stated that the toponymy of northern Mazovia tends to have unclear etymology (p. 30). Originally, Warszawa was the name of a fishing village. According to one theory Warszawa means "belonging to Warsz", Warsz being a shortened form of the masculine name of Slavic origin Warcisław; see also etymology of Wrocław. However the ending -awa is unusual for a big city; the names of Polish cities derived from personal names usually ending in -ów/owo/ew/ewo (e.g. Piotrków, Adamów) while the -av- in the early name of Wrocław is part of a personal name. Folk etymology attributes the city name to a fisherman, Wars, and his wife, Sawa. According to legend, Sawa was a mermaid living in the Vistula River with whom Wars fell in love. In actuality, Warsz was a 12th/13th-century nobleman who owned a village located at the modern-day site of the Mariensztat neighbourhood. See also the Vršovci family which had escaped to Poland. 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).
