1.- YIDDISH:
Yiddish was the international language of Ashkenazic Jews (the Jews of Central and Eastern Europe and their descendants). A hybrid of Hebrew and medieval German, Yiddish takes about three-quarters of its vocabulary from German, but borrows words liberally from Hebrew and many other languages from the many lands where Ashkenazic Jews have lived. It has a grammatical structure all its own, and is written in an alphabet based on Hebrew characters. Scholars and universities classify Yiddish as a Germanic language, though some have questioned that classification.
Actually there are 3.000.000 people who speak yiddish.
2.-MAORI:
The Māori are the indigenous Polynesian people of New Zealand. There are about 700.000 people who speak maori.
