'''Luxembourg''' ( ;  ; ; ), officially the '''Grand Duchy of Luxembourg''', is a landlocked country in Western Europe. It is bordered by Belgium to the west and north, Germany to the east, and France to the south. Its capital, Luxembourg City, is one of the four official capitals of the European Union (together with Brussels, Frankfurt, and Strasbourg) and the seat of the Court of Justice of the European Union, the highest judicial authority in the EU. Its culture, people, and languages are highly intertwined with its neighbors, making it a mixture of French and German cultures. Luxembourgish is the only national language of the Luxembourgish people, as defined by law. In addition to Luxembourgish, French and German are used in administrative and judicial matters; the three languages are jointly considered administrative languages of Luxembourg.
