Thanks Matti
Yes my wife has already tried to explain some of the more interesting aspects of the Finnish language to me, such as your odd endings. One aspect of this is the creation of very long words which seems to make at least me run out of breath halfway!

Guess I am either too old or too stupid to catch on to such intricacies since they seem to enter one ear and disappear out of the other....

Anyway, I wonder why neither Prien et all and Mombeek has noticed this one.
Maybe it is in an update somewhere, I never checked that (too many books...)
Cheers
Stig
