A Dolphin and an Astronomer The dolphin wanted Sagan to scratch his stomach again, as the astronomer had done twice before. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water and made a sound just like the word more. The astonished astronomer went to the director of the institute and told him about the incident. Oh, yes. Thats one of the words he knows, the director said, showing no surprise at all. A language is not just a collection of sounds, or even words. A language has a structure and what we call a grammar. The structure and grammar of a language help to give it meaning. For example, the two questions Who loves Mary? and Who does Mary love? mean very different things. If you stop to think about it, you will see that this difference doesnt come from the words in the question but from the difference in structure. That is why the question Can dolphins speak? cant be answered until we find out if dolphins not only make sounds but also arrange them in a grammatical order which affects their meaning.
