Wikipedia:
Hungarian is the official language of Hungary and one of the 24 official languages of the European Union. Outside Hungary it is also spoken by communities of Hungarian people in neighboring countries—especially in Romania, Slovakia, Serbia and Ukraine—and by Hungarian diaspora communities worldwide. Like Finnish and Estonian, it belongs to the Uralic language family, with its closest relatives being Mansi and Khanty. It is one of the few languages of Europe that are not part of the Indo-European family.

The Hungarian name for the language is magyar [ˈmɒɟɒr] or magyar nyelv (About this sound listen ). The word "Magyar" is also used as an English word to refer to Hungarian people as an ethnic group, or to the language.
