Africa is said to be a treasury of language, in which, though the number varies depending on the classification, more than two or three thousand of languages are spoken. Among them, we see Swahili in this work, which is one of the Bantu languages and the most spoken mainly in East Africa as a common language. The Swahili sentence structure is very different from the European languages, which reflects the different view of the world and way of thinking. The world is not classified in two; male and female, but in eight classes. What they think important is not always the same as in European languages. Nevertheless, there must be the universal sentence structure based on the space-time cognition, while it is a human language. We intend to verify the hypothesis that all language is based on the universal sentence structure restricted by the space-time cognition no matter how the grammar is various.
