Let me tell you a little of the swedish alphabet:
In English the alphabet starts with ABCDEF and ends with XYZ.
In Swedish it starts with ABCDEF but ends with XYZÅÄÖ.
Å is considered being a letter of its own, not just an A with a ring, and is pronounced differently.
I think Å is most famous for abroaders for the Swedish scientist Ångsröm. The unit of a tenth of a billionth meter (?) is named after him.
Also the Swedish word 'smörgåsbord' has been knowed by the foreign culinaric audience.
So, yes, Åtta (eight) is the last one figured number in the Swedish word list.
