The oldest runestones in Sweden are written in a language that was called Old Scandinavian (or Proto Norse). In that time the language was understtod throughout Scandinavia.
I visited one of the runestones in Järsberg, Sweden, in the summer. And I encountered a verbform that is still easily read today: ᚹᚫᚱᛁᛏᚢ writu (write). So despite the almost 1500 years there is still something very common with the language.
