【正确答案】正确答案： Arbitrariness refers to the fact that the forms of linguistic signs bear no natural relationship to their meaning. Onomatopoeic words are the words that sound like the sounds they describe. Only when people know the meaning can they infer that the linguistic sign is appropriate for the exact sound. Arbitrariness of language makes it potentially creative, and conventionality of language makes a language be passed from generation to generation.
