Ido
In 1927, some serious disagreements divided the Idist movement. The appearance in 1922 of another auxiliary language, Occidental, and the reappearance of the argument between stability and change weakened Ido. For his part, Otto Jespersen, who broke away from the Idist movement, published his own linguistic project, Novial, in 1928. Novial, which contains many features of Ido while eliminating the more conspicuous elements of Esperanto (for example, noun endings in -o, adjectives in -a or conjugation, in -is, -as, -os) attracted some Idists like Ahlberg whose Idist newspaper Mondo became a Novialist magazine.
