Official minority languages of Sweden
Finnish has been spoken in Sweden ever since the (then provincial) borders were drawn in the 13th century. Sweden has always had a significant migration to and from Finland. As the two languages belong to different language families it is easy to distinguish them, unlike the neighbouring languages Norwegian and Danish. The number of Finnish speakers in Sweden today has been estimated to over 460,000. Even though many current Swedes are of full or mixed Finnish descent, Swedish is the main language in practice for many bilinguals.
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".
