Denmark
A large majority (86%) of Danes speak English as a second language, generally with a high level of proficiency. German is the second-most spoken foreign language, with 47% reporting a conversational level of proficiency. Denmark had 25,900 native speakers of German in 2007 (mostly in the South Jutland area).
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.
