The name of Sweden was originally a plural form of Swede and is a so-called "back-formation", from Old English Sweoðeod, which meant "people of the Swedes" (Old Norse Svíþjóð, Latin Suetidi). This word is derived from Sweon/Sweonas (Old Norse Sviar, Latin Suiones). As the name for the country itself, Sweden is borrowed from Dutch Zweden, which is probably the dative case of Zwede. It appeared in Scots during the 17th century in forms such as Swethin and Swadne. Before this, Sweden was called Swedeland, and in Old English it was called Sweoland (see Svealand) or Sweorice (Old Norse Sviariki, which is an older form of the modern Swedish name for the country, Sverige).
