In dutch you have beside natuurkunde (physics) and scheikunde (chemistry) also for example bestuurskunde (government) and bedrijskunde (business) so it in a lot of scientific disciplines, but putely the -kunde part better translates to knowledge of a skill (wij kunnen = we can), than science in general. I don't know Latin or ancient Greek but I guess it's the germanic counterpart of -logy in psychology and technology. In that case it could be like knowlogy, which sounds cool, but I am no expert.
