So control of the country’s finances required control of its main trading centres. To that end, in 1550 Gustav Vasa founded a new harbour city on the northern shore of the Gulf of Finland, at Vanda fors (stream) in the parish of Helsinge. It was called Helsingfors, still its Swedish name, known in Finnish as Helsinki. (bolds by me)
A history of Finland by Henrik Meinander
In the bolded sentence, author says that "Gustav Vasa founded a city at Vanda fors" and translator (who translated the book from Swedish) added the word "stream" in the brackets. The original version of the text didn't have the word "stream". When I google it I have found Vandaforsen in wikipedia. But this wikipedia page has no English version so I can not come to a conclusion about the geographical category of this place (Vandaforsen). I don't know if it is the name of a stream, a city, or what?
Is there any special meaning in the separation of the "Vanda" and "fors"? In the original text also these words are separated.
When I translated the word "fors" form Swedish I have found that one of its meanings is "stream". But I am not sure whether or not a city can be founded at a stream? It that possible?
Ultimately my question is what does separated "Vanda fors" mean and is its meaning any different from "Vandaforsen"? And what is the geographical category of the place called "Vandaforsen"?
