Don’t know if “Berber” is politically incorrect but… these are some resources on various Berber languges, which I came across by chance. Generally interesting blog as well 
Berber does offend some, apparently. I personally see no harm in it, the “berber” people have a great heritage to be proud of so they shouldn’t see the term as downgrading whatsoever, i think.
Thanks for the resources Jonquix, keep it up! :okay:
