Swedish is closest to its fellow Scandinavian languages, Danish and Norwegian. All three languages are part of the North Germanic language group and are somewhat mutually intelligible. - Norwegian is considered the most similar language to Swedish in terms of vocabulary and grammar, and spoken forms of Norwegian, especially the Bokmål variety, are quite easily understood by Swedes. - Danish is more closely related to Swedish in writing, but the pronunciation can be trickier for Swedish speakers to understand, though they can still generally communicate.
