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
Old Swedish (Swedish: "fornsvenska") is the term used for the medieval Swedish language. The start date is usually set to 1225 since this is the year that "Västgötalagen" ("the Västgöta Law") is believed to have been compiled for the first time. It is among the most important documents of the period written in Latin script and the oldest Swedish law codes. Old Swedish is divided into "äldre fornsvenska" (1225–1375) and "yngre fornsvenska" (1375–1526), "older" and "younger" Old Swedish. Important outside influences during this time came with the firm establishment of the Christian church and various monastic orders, introducing many Greek and Latin loanwords. With the rise of Hanseatic power in the late 13th and early 14th century, Middle Low German became very influential. The Hanseatic league provided Swedish commerce and administration with a large number of Low German-speaking immigrants. Many became quite influential members of Swedish medieval society, and brought terms from their native languages into the vocabulary. Besides a great number of loanwords for such areas as warfare, trade and administration, general grammatical suffixes and even conjunctions were imported. The League also brought a certain measure of influence from Danish (at the time much more similar than today's language).
