No one knows how man learned to make words.perhaps he began by imitating animals. Perhaps he imitated sounds he heard all around him: the crashing of ocean waves, bees buzzing, or a stone falling to the ground. In some way he learned to make words. As the centuries went by, he made more words. This is what we mean by language. The words we know are our vocabulary. We should try to expand our vocabulary Whenever possible. We should read as many books as we can, too. Of course, we most likely come across words we didn't know before. When we find a new word, we should look it up in the dictionary. The dictionary is our most useful book of all.
