But the amount of Norse words which entered in to English is substantial (even if the meaning has shifted slightly) - and the cultural hangovers of the Viking raids in northern England are quite a lot. The main shopping street in Leeds is "Briggate" - using the old Norse word "gata" for street. Home / heim. Loft (IS for sky) / aloft (EN meaning above). The classic ones of berzerk, saga, jul/yule (Christmas), the days of the weeks being mostly after Norse gods (so are very similar), etc etc. Traditionally, up north, it was common to leave kids to sleep outside in the prams, even when it was bloody cold - it was thought to be good for the lungs, which is the same in Nordic countries. I've never seen anyone doing that or even having heard of doing it in southern England.
