Languages of Sweden
In 2009, the Riksdag passed the Language Law recognizing Swedish as the "main" and "common" language of society as well as being the official language in "international contexts", the five national minority languages, and Swedish sign language .
Swedish language
In the 8th century, the common Germanic language of Scandinavia, Proto-Norse, evolved into Old Norse. This language underwent more changes that did not spread to all of Scandinavia, which resulted in the appearance of two similar dialects: "Old West Norse" (Norway, the Faroe Islands and Iceland) and "Old East Norse" (Denmark and Sweden). The dialects of Old East Norse spoken in Sweden are called "Runic Swedish", while the dialects of Denmark are referred to as "Runic Danish". The dialects are described as "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 had only 16 letters. Because the number of runes was limited, 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", also used for "e".
