köken: From Proto-Finnic *visa (“hard?”). Cognate with Estonian visa, Karelian visa and Livonian vizā. The original adjective "hard, difficult, demanding" is now exclusively found in dialects (and some derivations, like visakoivu); the modern sense "quiz" is a backformation of visailla, itself derived from that adjective.
