The declension of Finnish nouns is more complicated that conjugating Finnish verbs. The reason is that the number of verbs is more limited in Finnish, and even loan words are formed to verbs with specific endings.
Nouns on the other hand can take (almost) any shape. And loan words can be used as such, with the Finnish noun endings of course. So you could take the English word ‘sting’, and apply inflectional endins to it.
