I didn't want to believe it when I first saw it. For the first time ever a word which is the same as Italian!
Skriva is a very old loan from Latin, so that explains it.
There are more, but I guess most of them for the same reason Lundgren8 mentions. The only one that springs to mind right now is kosta for costa (as in Quanto costa?)
Is there a way to know when a verb will end in er or ar?
