Fantastic that Norwegian finally is here! As a native speaker I've been looking forward to go through the course. Good luck to all of you who want to try out Norwegian! You will not regret it, I promise. I believe it's easy to learn for german and english speakers. I'll be glad to help anyone, please send me a message if there is anything! :)
I would learn Norwegian personally. (as long as you have no previous specific reasons to learning a specific one, e.g. ancestry from Sweden.) Norwegian is considered "in-between" Danish and Swedish. Norwegian speakers generally understand Swedish and Danish better than the Danes can understand Swedish or vice-versa. Norwegian's grammar is quite close to Danish, and so is it's written form. However, spoken Norwegian sounds much closer to spoken Swedish, which makes it easy to understand. I'm not fluent in Norwegian, but I can already understand some Swedish speakers. :) Hope that helped!
Masculine: en mann (a man) Feminine: ei jente (a girl) Neutral: et menneske (a human) En ei et
Masculine: mannen (the man) Feminine: jenta (the girl) Neutral: mennesket (the human) -en -a -et
Masculine form is taking over feminine in newer language, watering down the grammar. But in general genders reflect real life genders, unlike german.
