Outside of Sweden, where the Swedish language has been required by law to be used and developed by all government agencies since 2009, Swedish is also recognised as an official language in Finland. Conversely, however, Swedish is the sole official language in Sweden. One interesting fact about the Swedish language concerns the term "Svorsk". The Norwegian colloquial language is so interspersed with words and idioms taken from Swedish that Swedes and Norwegians can converse with each other without any problems.
