Old
West Norse vs. Old East Norse
vFrom the start of the
Viking Age (ca. 800 A.D.) there began to be noticeable differences in pronunciation between Norway and the
Norse colonies in the North Atlantic
vs. Sweden, Denmark, and colonies in the Baltic. These differences are enough that scholars recognize two dialects of Old
Norse, Old West Norse (Norway, Iceland,
Greenland, etc.) and Old East Norse (Sweden, Denmark). There still wasn't a lot of difference, it was more like the difference
between British English vs. American
English.
Continental
Languages Cause Changes in Old East Norse
vOver time, Sweden and
Denmark had a lot of direct trade and influence from the Continent, particularly from Germany, and these
influences led to changes in pronunciation.
Norway saw some changes in its language, but Icelandic (far away in the Atlantic) changed very little. By 1250 A.D. or so,
the Scandinavian languages had diverged
enough that one can term them from this point Old Icelandic, Old Norwegian, Old Swedish, and Old Danish.
