Ido Language

Ido is a constructed language that was derived from Reformed Esperanto. Indeed, the name Ido is derived from the Esperanto word "ido," meaning "offspring," since the language is a "descendant" of Esperanto.

It was designed with the goal of being a universal second language for people of diverse backgrounds. Ido has a regular grammar with no exceptions, making it one of the easiest languages to learn. It was created by a group of linguists and scientists including Louis Couturat, Otto Jespersen, and Louis de Beaufront, who were members of the Uniono por la Linguo Internaciona Progreso (Union for the International Language Progress).

Ido is a reformed and simplified version of Esperanto, which was developed in the late 19th century by L. L. Zamenhof. Esperanto was intended to be a universal second language, but it did not gain widespread adoption. Ido was created to address some of the perceived shortcomings of Esperanto, such as its irregularities and its use of diacritical marks. Ido was designed to be more intuitive and easier to learn than Esperanto, and it has been used by a small but dedicated community of speakers around the world.

History of Ido

Adoption and Evolution

Ido was presented at the Uniono por la Linguo Internaciona (Union for the International Language) in 1907, and it quickly gained popularity among Esperanto speakers. The language was also supported by the scientific community, with prominent scientists such as Wilhelm Ostwald endorsing its use.

In 1908, the Delegation for the Adoption of an International Auxiliary Language was established to promote the adoption of a universal second language. Ido was one of the languages considered by the delegation, and it was ultimately chosen as one of the six languages to be studied further.

Over the years, Ido has continued to evolve and develop, with changes made to its grammar and vocabulary. The language has also been used by various organizations and individuals for international communication, although it has never achieved the widespread adoption of Esperanto.

Despite its limited use, Ido remains an important part of the history of constructed languages, and its development has influenced the creation of many other constructed languages in the years since its creation.

Ido Linguistics

As mentioned, Ido is known for its simplified grammar, pronunciation, and vocabulary, which makes it easier to learn than ethnic languages. In this section, we will explore the linguistic features of Ido, including its grammar, pronunciation, and vocabulary.

The accusative is marked by the suffix "-n", which is added to the end of the word. Ido also uses adjectives to modify nouns, and the adjective always comes before the noun it modifies.


Ido pronunciation is based on the International Phonetic Alphabet (IPA). It has 25 consonants and 5 vowels. The consonants are pronounced similarly to those in English, while the vowels are pronounced similarly to those in Spanish. Ido does not use diacritics, which makes it easier to type and read.


Ido contains words from many different languages, including English, French, German, Italian, and Spanish. Ido also uses affixes to modify the meaning of words. For example, the prefix "dis-" means "not" or "opposite", while the suffix "-ist-" means "one who practices or believes in".

Comparison with Other Languages


Ido is a constructed language that was derived from Esperanto, and it is therefore no surprise that it shares many similarities with its predecessor. However, Ido was designed to be more regular and easier to learn than Esperanto. For example, Ido has a simpler grammar with fewer irregularities, and its vocabulary is more international, making it easier for people from diverse backgrounds to learn and use as a universal second language. Despite these differences, Esperanto and Ido are both constructed languages that aim to be auxiliary languages that are easy to learn and intelligible to speakers of different languages.


Novial is another constructed language that was created in the early 20th century as an auxiliary language. Like Ido, Novial was designed to be easier to learn and more regular than its predecessor, Esperanto. However, Novial's grammar and vocabulary are quite different from Ido's, and it is less widely spoken. Novial uses a simplified system of verb conjugation and noun declension, and its vocabulary is based on a combination of Germanic and Romance languages.


Interlingua is a constructed language that was developed in the mid-20th century as an auxiliary language. Unlike Ido and Novial, Interlingua is based on natural languages, particularly Romance languages, and it aims to be intelligible to speakers of these languages. Interlingua's grammar and vocabulary are therefore more similar to those of natural languages than to those of constructed languages like Ido.


Latin is a classical language that has had a great influence on the development of many modern languages, including English. Although Ido and other constructed languages were not directly influenced by Latin, they share some similarities with it, such as a highly regular grammar and a large number of international words. However, Latin is a dead language that is no longer spoken as a native language, whereas Ido and other constructed languages are designed to be spoken and used as auxiliary languages.


English is a global language that is widely spoken and used as a second language by people all over the world. Although English and Ido are quite different in many respects, they share some similarities, such as a large number of international words and a relatively simple grammar. However, English is a natural language that has evolved over many centuries, whereas Ido is a constructed language that was designed to be easy to learn and use as a universal second language.

Criticism and Controversy

Ido language has faced criticism and controversy since its inception. Although Ido was created to be an improvement over Esperanto, some critics argue that Ido did not go far enough in simplifying the language.

Another criticism of Ido is that it is not unique enough from Esperanto to justify its creation. Some people argue that Ido is simply an Esperanto clone with a few tweaks, and that it does not offer any significant advantages over Esperanto.

There has also been controversy surrounding the use of Ido in the international language community. Some people argue that Ido has not gained the same level of popularity as Esperanto because of a lack of promotion and awareness. Others argue that Ido has not gained popularity because it is not as easy to learn as Esperanto.

Despite these criticisms and controversies, Ido continues to have a dedicated following of speakers and enthusiasts. Many people appreciate the efforts of Ido's creators to improve upon Esperanto and create a more streamlined and efficient international language.
