Thanks, AKS. I'm interested in languages, and Finnish is so different from English. It's intriguing.

Morwen, I'm not a drinker, and to me all booze tastes rather bad, some worse than others. I think vodka smells rather like paint stripper. There are people who imagine that other people won't realize they have been drinking if they stick to vodka. While it's true vodka doesn't have the strong 'dark' flavors of whiskey, I know someone's been drinking it because their breath smells, as I say, like paint stripper.

Some distiller used to advertise their vodka with "It leaves you breathless." Ha!

The possibility that the name 'Kullervo' is linked to gold might be a good one to exploit in your retelling. Perhaps he will be denied the chance to become a blacksmith and will become a magical goldsmith instead.
