Flexione

In 1903 Peano announced his work on an international auxiliary language called Latino sine flexione (" Latin without inflexion," later called Interlingua, and the precursor of the Interlingua of the IALA ).

Interestingly, the Interlingua presented by the IALA is very close to Peano’s Interlingua (Latino sine flexione), both in its grammar and especially in its vocabulary.

Several other languages such as Latino sine Flexione and Idiom Neutral had also been put forward.

The comments and examples were written in Latino sine flexione.
