Ido: a Simple, Logical & International Language


that make this language marvelous

No diacritics, facultative accusative, few exceptions. Pronunciation is coherent. One can learn all rules of Ido in just a few hours. Imagine!


In Ido, the core of the words are the roots. To precise the sense provided by a root, one uses universal prefixes and suffixes, just like LEGO® bricks!


The roots are based on the English, French, Italian, Russian and Spanish languages. Result: a language intelligible by millions in all continents!


Ido is unbiased. Words are by default neither masculine nor feminine. Are you small? Left-handed? Elderly? It is not “bad”!
