Languages of Sweden
Swedish is the official language of Sweden and is spoken by the vast majority of the 10 million inhabitants of the country. It is a North Germanic language and quite similar to its sister Scandinavian languages, Danish and Norwegian, with which it maintains partial mutual intelligibility and forming a dialect continuum. Five "national minority languages" are also recognized by Swedish law: Finnish, Yiddish, Meänkieli, Romani and Sami.
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.
