Norwegian is the easiest language for English speakers to learn as a second language. Norwegian is a member of the Germanic family of languages — just like English. This means the languages share quite a bit of vocabulary, such as the seasons 'vinter' and 'sommer' (winter/summer).

Another part of learning Norwegian: the grammar is pretty straightforward, with only one form of each verb per tense. And the word order closely mimics English. For example, “Can you help me?” translates to 'Kan du hjelpe meg?' — the words are in the same order in both languages, so mastering sentence structure is rather simple.

Norwegian is a descendant of 'Old Norse', the common language of the Germanic peoples living in Scandinavia during the Viking Era. Today, there are two official forms of written Norwegian, 'Bokmål' (literally "book tongue" from Danish origins) and 'Nynorsk' ("new Norwegian"), each with its own variants.

There is a lot of leeway with pronunciation when learning Norwegian. That’s because there are a vast array of different accents in Norway and, therefore, more than one “correct way” to pronounce words.

Norwegian nouns belong to three noun classes (genders): masculine, feminine and neuter. In comparison, the use of all three genders (including the feminine) is mandatory in 'Nynorsk'.
