With all the open air ice skating going on at the moment, I am reminded of the Swedish expression ‘Det är ingen ko på isen’ or ’there’s no cow on the ice’. This expression is used to mean there is ‘ no need for worry’ or ‘don’t be concerned’. So, where does the expression originate?
Well, like many Swedish expressions, this one also has a rural origin. In the old days, farmers that had no running water would take their cows down to the lake to drink. As long as the cows stayed on land, and didn’t venture onto the frozen waters, there was no risk of them falling through the ice and drowning. In fact, the expression is an abbreviation of the longer saying ‘there’s no cow on the ice as long as their rear end is on land’. (Det är ingen ko på isen så länge stjärten är i land.) As long as they had a firm footing, they could rescue themselves if the ice broke around the periphery of the lake.
So it would seem that the original meaning of the saying might have been ‘there is no need for worry as long as you take precautions.’
