Svenska Starka Verb

This wheel would have come in very handy when I was trying to learn Swedish. I bought this in Stockholm, so it's brand new. It's 8 inches in diameter. "Starka Verb" means, I believe, strong verb. I don't know what most of these mean, but I know how to pronounce most of them. I'm afraid that won't get me very far. Good thing most people in Sweden speak Engelska.
