What is the languish of Denmark?

The language of Denmark is danish. Danish is a language unique to Denmark, however other Nordic countries (Sweden, Norway) have languages that are so similar to danish, that it is possible to have a conversation without having actually learned the other language.
Danish has a Teutonic heritage and has influenced english language, mostly regarding to place names in england, but also regarding to some words like brother (broder), sister (søster), wind (vind), and so on.

Though danish is the national language almost every Dane can speak english as well, and all children are taught german, french or spanish in school.
