Tutonish based on Germanic
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, and he reformed it multiple times, in 1906 under the name nu teutonish, in 1911 under the name altutonish and in 1915 under the name alteutonik. It is known to be the first Pan-Germanic language.
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.
