The Norwegian alphabet has 29 letters, 3 more vowels than in French: the « æ », « å » and « ø ».
The « o » are pronounced [o] in front of two consonants and [u] or [or] in front of one consonant, the « e » are pronounced [a], some « y » are pronounced [or] too.
Sometimes we don’t pronounce certain consonants in the middle or end of the word.
Well, some difficulties then!

There are 3 official languages: bokmål, nynorsk and sámi, and more than 100 different dialects.
In fact, there are ways of speaking and specific words in each region.
A dialect is not just an accent, they use different words and Norwegian is a tonal language.
Sometimes even native Norwegians find it difficult to understand each other because of dialects.
