Danish is the official language in Denmark. However, about 86 percent of Danes also speak English, which is taught in schools. In Greenland and the Faroe Islands, Danish is the second official language alongside the respective national language and is recognised as a minority language. In Schleswig-Holstein, in Germany, Danish is also protected by the constitution of the country and in Glücksburg and Flensburg there have been bilingual place signs for several years.
