If the characters from Frozen were real historical figures in 2026, they would primarily speak Norwegian. The fictional kingdom of Arendelle is heavily inspired by 19th-century Norway, specifically the city of Bergen. In a real-world context, they would likely speak a dialect of Norwegian known as Bokmål or its predecessor, and as members of the royalty, they would also be fluent in French, which was the international language of diplomacy and European courts during that era. Interestingly, the film's intro uses Old Norse-inspired chanting, suggesting that their cultural and religious ceremonies might involve Old Norse, the ancient language of the Vikings that laid the foundation for modern Scandinavian tongues.
