when did swedish become the official language of sweden
Languages of Sweden Swedish evolved from Old Norse around the 14th and 15th century, and historically, the Swedish dialects were generally much more different than today. Since the 20th century Standard Swedish prevails throughout the country. The Scandinavian languages constitute a dialectal continuum and some of the traditional Swedish dialects could equally be described as Danish (Scanian) or Norwegian (Jamtlandic).
English language English is a North Sea Germanic language that was first spoken in early medieval England and is now a global lingua franca.[4][5] Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea. It is closely related to the Frisian languages, but its vocabulary has been significantly influenced by other Germanic languages, particularly Norse (a North Germanic language), as well as by Latin and Romance languages, especially French.[6]
