Swedish is a North Germanic language, spoken by more than nine million people, predominantly in Sweden and parts of Finland, especially along the coast and on the Åland islands. It is to a considerable extent mutually intelligible with Norwegian and to a lesser extent with Danish. Along with the other North Germanic languages, Swedish is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era.
The Swedish alphabet is a 29-letter alphabet, using the basic 26-letter Latin alphabet plus the three additional letters Å / å, Ä / ä, and Ö / ö constructed in modern time from the habit of writing the later letter of ao, ae and oe on top of the former. Though these combinations are historically modified versions of A and O according to the English range of usage for the word diacritic, these 3 characters are not considered as diacritics within the narrower Swedish application since they are sorted in that order following z as independent letters. Before the release of the 13th edition of Svenska Akademiens Ordlista in April 2006, w was treated as merely a variant of v used only in names (such as "Wallenberg") and foreign words ("bowling"), and so was both sorted and pronounced as a v. Other diacritics (to use the broader English word usage referenced here) are unusual in Swedish; é is sometimes used to indicate that the stress falls on a terminal syllable containing e, especially when the stress changes the meaning (ide vs. idé); occasionally other acute accents and, less often, grave accents can be seen in names and some foreign words. The letter à is used to refer to unit cost, equivalent to the at sign (@) in English.
