In English, when we suspect something isn’t quite right we ‘smell a rat’. In Swedish, they suspect ‘owls in the moss’.
The expression – ‘att ana ugglor i mossen’ – has Danish origin. The original saying dates to the 1600’s and was ‘det är ulve i mosen’ which translates as ‘there’s a wolf in the moss’. The expression makes sense and was used when a dangerous situation was suspected.
So, how did a wolf turn into an owl? There are two theories. One theory is that it happened as a mistake. The sound of the Danish word for wolf ‘ulve’ was misheard as ‘uggla’ the word for owl – and the creature hiding in the moss became a wise bird rather than a viscous predator.
Another theory is that the saying was consciously changed when wolves disappeared from Denmark. The wolf was replaced by an owl because it hoots a warning at the presence of danger.
