Another problem with beginning an IAL development at the second “grammatical” level is that the linguistic foundation has been laid in different ways in different cultures. Thus there is a great difference between analytic grammar which relies heavily on word order and synthetic grammar which uses inflections, especially when there are different orderings of subject, verb and object within the sentence. By returning to linguistic universals at the verbal rather than the grammatical level there is more of a common foundation for progress. For example, speech sounds uttered by infants around the world are much more similar than the advanced languages of the various nations. Thus it can readily be seen that a start at the very beginning would provide a more realistic common foundation for linguistic progress.
