In Copenhagen, the mother tongue is Danish, which is closely related to both Swedish and Norwegian. In general Danes speak English extremely well, and some even German and French.

In the Danish schools, English is taught from a very early age alongside German and to some extent French. Music and mass media have made their impact too. Films and TV programmes are always broadcasted in the original language with Danish subtitles.

The older generation who went to school during WW1 ususally know German better than they know English.
