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.
History of Swedish
Old East Norse is in Sweden called "Runic Swedish" and in Denmark "Runic Danish", but until the 12th century, the dialect was the same in the two countries. The dialects are called "runic" because the main body of text appears in the runic alphabet. Unlike Proto-Norse, which was written with the Elder Futhark alphabet, Old Norse was written with the Younger Futhark alphabet, which only had 16 letters. Due to the limited number of runes, some runes were used for a range of phonemes, such as the rune for the vowel "u" which was also used for the vowels "o", "ø" and "y", and the rune for "i" which was also used for "e".
