Sweden
The official language of Sweden is Swedish, a North Germanic language, related and very similar to Danish and Norwegian, but differing in pronunciation and orthography. Norwegians have little difficulty understanding Swedish, and Danes can also understand it, with slightly more difficulty than Norwegians. The same goes for standard Swedish speakers, who find it far easier to understand Norwegian than Danish. The dialects spoken in Scania, the southernmost part of the country, are influenced by Danish because the region traditionally was a part of Denmark and is nowadays situated closely to it. Sweden Finns are Sweden's largest linguistic minority, comprising about 5% of Sweden's population, and Finnish is recognised as a minority language. Owing to a recent influx of native speakers of Arabic in latter years, the use of Arabic is likely more widespread in the country than that of Finnish. However, no official statistics are kept on language use.
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".
