The native Japanese words constitute the largest category, followed by words originally borrowed from China in earlier history, and the smallest but a rapidly growing category of words borrowed in modern times from Western languages such as English. This third category also contains a small number of words that have come from other Asian languages. Studies by the National Language Institute show that the frequency of these three types of words varies according to the kinds of written material examined. In newspapers, the words of Chinese origin number greater than the Japanese native words. Unlike English, which has stress accent, Japanese has pitch accent, which means that after an accented syllable, the pitch falls.
Every language has a basic word order for the words in a sentence.
The rule of thumb in Japanese is that in a sentence, the verb comes at the end. These are called case markers, and a large number of the world's languages have them. If we go back in history, the older English of five hundred to one thousand years ago had an extensive case-marking system similar to modern Japanese. These case markers make it possible for the words in Japanese to appear in different orders and retain the same meaning. If we have a more complex sentence, it is still possible to change the order of all the words as long as the verb remains at the end.
