Languages of Sweden
The Kingdom of Sweden is a nation-state for the Swedish people, and as such, their national language is held in very high regard. Of Sweden's roughly ten million people, almost all speak Swedish as at least a second language, and the majority as a first language (7,825,000, according to SIL's Ethnologue). Swedish is also an official language in Finland where it is spoken by a large number of Swedish-speaking Finns. The language is also spoken to some degree by ethnic Swedes living outside Sweden, for example, just over half a million people of Swedish descent in the United States speak the language, according to Ethnologue.
Swedish as a foreign language
Swedish belongs to the North Germanic branch of the Germanic sub-family of the Indo-European languages. As such, it is mutually intelligible with Norwegian and Danish. Because most of the loanwords present in Swedish come from English and German (originally Middle Low German, closely related to Dutch), and also because of similarities in grammar, native speakers of Germanic languages usually have an advantage over speakers of other, less related languages.
