【正确答案】正确答案：Linguistic relativity is one of the two points in Sapir-Whorf hypothesis, which states that distinctions encoded in one language are unique to that language alone, and "there is no limit to the structural diversity of language". Therefore, similarity between languages is relative, the greater their structural differentiation is, the more diverse their conceptualization of the world will be. For example, in English, the boundaries among the color spectrum are made in this way: red, orange, violet, blue, and yellow. In fact, these discriminations are arbitrary, and in other language the boundaries are indeed different. In neither Spanish, Italian nor Russian is there is a word that corresponds to the English meaning of "blue". Linguistic relativity is important in linguistic studies because it recognizes the fact of linguistic diversity, which stands as the base which descriptive linguistics lies on. Linguistic diversity also triggers out the study of the linguistic similarity. The study of the linguistic relativity has shed light on two important insights: there is nowadays recognition that language, as a code, reflects cultural and preoccupations and constrains the way people think.
