The city was named after the Geats (Swedish: Götar varied: Geata,Gautar, Goths, Gotar, Gøtar, Götar), the inhabitants of Gothia, now southern Sweden—i.e., "Geat Castle". The river on which the city sits is the Göta älv or Gothia River. Göta borg "Gothia Fortress" is the fort on the Göta River, built to protect the port, which was intended to be Sweden's commercial window to the west.
In Dutch, Scots, and English, all being languages with a long history of being spoken in this trade and maritime-oriented city, the name Gothenburg is used for the city. The French form of the city name is Gothembourg but in the French texts, the Swedish name Göteborg is more frequent. Gottenburg can also be seen in some older English texts. These traditional forms are now sometimes replaced with the use of the Swedish Göteborg, for example by the Göteborgsoperan and the Göteborg Ballet.
Mangal Sen Jindal writes: ...The Southern portion of Sweden as 'Gotland' wherein the name of a city is 'Goteborg'. In Baltic Sea, there is a big island which used to be a trade centre of importance sometime back is named 'Gothland', The words are definitely connected with Jats or Goths.
