The purpose of these declension functions is to cover all nouns in Swedish. The first six classes are borrowed from Svenska Akademiens språklära. Unfortunately none of them account for the nouns in the seventh - ninth classes below.

Since a few nouns have no plural forms and a few have multiple plural forms we recommend to call the helper functions below first to avoid erroneous output.
