Ido is the International and Neutral Auxiliary Idiom selected by «The Delegation for the Adoption of an Auxiliary International Language». The Delegation was appointed in 1901 and in 1907 it had received the adherence of 310 Societies of all Countries, and was approved by 1,250 members of Academies and Universities. It elected an International Committee of Scholars (savants) and linguists, who, after having examined all ancient and modern attempts to compile a satisfactory International Language, in October, 1907, adopted a reform and simplification of Esperanto, submitted under the pseudonym of « IDO ». Therefore the System is the result of collective labour, and not the product of an individual inventor.

Ido appeals to the greatest number of peoples by the maximum internationality of its word roots, and by its extreme simplicity. Ido has a flowing and harmonious pronunciation, which may be compared to that of Italian. Ido employs the characters of the International Alphabet (Anglo-Latin) only. It can therefore be printed, typewritten or telegraphed throughout the world without undergoing any alterations or modifications. Ido offends no national prejudice, its roots being essentially international. Unlike other systems it does not favour the educated Latinist at the expense of the general mass of people interested. Ido, better than any other System, can be used by the scientist in his researches and correspondence, by the merchant, by the collector and the tourist, each one for his particular needs. Ido can easily be learnt in a few weeks without a master (adopted from the Introduction); reprint of the original edition, London, 1918).
