2002, I have Su published a book 'From the Linguistic Law to the International language' ISBN 0-9581464-0-3. I found that the current international language such as Esperanto, Ido, Eurolang etc. didn't give their speakers any benefit. For instance Esperanto has created as much compound word and derivatives as possible. Indeed, it made the language easy to learn but on the other hand, this process makes the words longer than normal English words, in the average. Supposing it take just 0.2 second longer than English in average, it means to say 1/5 life of the speakers was wasted in oral action, without any information exchange. Beside this, as our thinking process is a sort of speaking in mind. That is to say our thinking process is cohered with speaking in some way. Once our speaking speed is slow down, our thinking speed would be slow down too.
Now, the Auxlang should refer a projecting language or a goal language. It is not invented by a single person but by the people of the world. The project divided by two steps. First step: Any language that wants to share the future IAL (International Auxiliary Language) should take a reform. Second step: After this reform, these languages could be learnt in a short time, so some governments (for instance German and France) may require their students learn both language then the jargon lead a new language (we may call it Gerench). Repeat this process; the world language will be united.
First step:
As very language has its unique property, so we can't suggest any thing to any single language. Linguists of that language should response the reform. They have to design the plan and maybe found their own school to achieve the reform. For the moment, we can only recommend the target as:
1. Reducing the basic words under 4,000. 2. Any other word could be substituted by a compound word from these 4,000 words. 3. The speaking speed should not slower than current language. 4. Every learner could pronounce any words properly when facing a writing material. 5. The ability of drawing information from other cultures and languages should be better than any other languages.
In other words, after learn the basic letters; any learner could pronounce any words exactly when facing the writing material. After learnt the 4,000 basic words, a learner should understand all the vocabulary no matter how many words it will have (for instance their compound words could substitute the current one million English words). This step is in fact helps the language attract more people to learn it and let its speaker enjoy more information during life time.
