I love how "rakastevagen" => "rakaste vägen" is Swedish for "the shortest path", but also sounds a bit Finnish to me, a non-Finnish speaker. Reminiscent of "rakastan", which a Swede would know from "minä rakastan sinua", or "I love you".
Because it's slightly surprising... Despite being neighbors, Swedish and Finnish are only distantly related. Finnish is closer to Hungarian, and Swedish is similar to the other Scandinavian languages and Germanic languages.
Rakaste vägen is the aggregation of the Finnish word Rakaste and the Swedish word vägen. There are quite a few words in Finnish that are borrowed from Swedish.
“Rakaste" is the superlative of the Swedish rak, meaning straight. It is not a Finnish word.
