Languages of Denmark
A large majority (86%) of Danes also speak English as a second language; it is mandatory for Danish students to learn from the first grade in the public elementary schools (), by far the most popular option in the country. In the 1st (or 3rd, depends on the school) grade of folkeskole, a third language option is given, usually German or French. The vast majority pick German (47% of Danes report being able to speak conversational German). The third most widely understood foreign language is Swedish, with 13% of Danes reporting to be able to speak it.
Danish language
Danish is largely mutually intelligible with Norwegian and Swedish. Proficient speakers of any of the three languages can often understand the others fairly well, though studies have shown that speakers of Norwegian generally understand both Danish and Swedish far better than Swedes or Danes understand each other. Both Swedes and Danes also understand Norwegian better than they understand each other's languages. The reason Norwegian occupies a middle position in terms of intelligibility is because of its shared border with Sweden resulting in a similarity in pronunciation, combined with the long tradition of having Danish as a written language which has led to similarities in vocabulary. Among younger Danes, Copenhageners are worse at understanding Swedish than Danes from the provinces, and in general, younger Danes are not as good at understanding the neighboring languages as are Norwegian and Swedish youths.
