I usually use the word Dutch, when I talk to you about my language. But I only recently found out that isn't the official term. It's actually Netherlandic. So I'll try to use that in future. Strange that I never knew this.
"Dutch language, the Netherlandic (Netherlandish) language as spoken in The Netherlands, together with the same language in northern Belgium, which is popularly called Flemish. In the European Middle Ages, the language was called Dietsc, or Duutsc, historically equivalent to German Deutsch and meaning simply "language of the people," as contrasted with Latin, which was the language of religion and learning. The official name of the language is Nederlands, or Netherlandic."
