Tutonish (also called Teutonish, Teutonik, Allteutonish, Altutonish, Alteutonik, Nu Teutonish, Niu Teutonish, or Neuteutonish) is a constructed language created by Elias Molee. He worked on it for several years before publishing it for the first time in 1901. He reformed it twice, first in 1906 and under the name N(i)u teutonish and then in 1915 under the name Alteutonik. It is known to be the first Pan-Germanic language.
In 1901 it first was proposed as an "Anglo-German unifying language", for English and Germanic languages speaking areas, not as an international language in the full sense of the word. Furthermore, Molee's work is only intended to be a zonal constructed language amongst English, Dutch, Scandinavian and German native speakers.
In creating it, Molee was clearly influenced by Giuseppe Peano but chose to create a language for people based on Germanic roots instead of Romance ones. However, he created an "inter-Romance" version of his language to be used among Romance-speaking people as well.
