     No one knows how man learned to make words. Perhaps he began by making sounds like those made

by animals. Perhaps he made sounds like those he heard all round him--water splashing (溅落), bees

humming, a stone falling to the ground. Somehow he learned to make words. As the centuries went by, he

made more and more new words. This is what we mean by language. People living in different countries

made different kinds of words. Today there are about fifteen hundred different languages in the world. Each

contains four or five hundred thousand words, but we do not need all of these. Only a few thousand words

are used in everyday life.
