【正确答案】正确答案：The creativity of language means that users can understand and produce sentences they have never heard before. Creativity is a property unique to human language. It is one of design features that only human language has. Human language is resourceful because of its duality and its recursiveness. The speaker is able to combine the basic linguistic units to form all infinite sets of sentences, most of which are never before produced or heard. The fact that human language is recursive could be shown in that words can be used in new ways to mean new things, and can be instantly understood by people who have never come across that word before. For example, I could make a sentence like The old lady who is waiting for the girl who is talking to the boy who is playing with a basketball is my grandma. Recursiveness also includes coordination and subordination, conjoining and embedding, hypotactic and paratactic. recursiveness, together with openness, is generally regarded as the core of creativity of language.
