Insular Danish
Insular Danish (Danish: "Ømål") are the traditional Danish dialects spoken on the islands of Zealand, Langeland, Funen, Falster, Lolland and Møn. They are recorded in the Dictionary of Danish Insular Danish ("Ømålsordbogen") which has been collected since the 1920s, and published in biannual volumes since 1992. There are significant differences between the different insular varieties, but they also share a number of features. A major difference is between Modern Danish and the traditional insular dialects are that some of them lack the stød but kept the tonal accent. Also, they kept three noun genders.
