Complex sentences in Norwegian grammar consist of a main clause and one or more dependent clauses. Sometimes, dependent clauses are introduced by subjunctions such as fordi (because), men (but), and hvis (if). Conjunctions like og (and), or (or), and så (so) are also used to connect simple sentences into complex sentences. Here, it is important to understand the grammatical structure of each clause and how the clauses relate to one another to form a comprehensive sentence.
