Unlike Boas, who had only suggested language as a measure of culture, Sapir proposed a mutual relationship between culture and language.
    When Sapir was teaching at Yale; Benjamin Lee Whorl enrolled in his class. A chemical engineers, Whorf neither sought nor obtained a higher degree in linguistics. His contribution to the science of language is nonetheless significant.
    Whorf was recognized for his investigations of the Hopi language, including his authorship of a grammar and a dictionary. Even in his early publications, it is clear that he was developing the theory that the very different grammar of Hopi might indicate a different manner of conceiving and perceiving the word on the part of the native speaker of Hopi.
    In 1936, he wrote his monumental work "An American Indian Model of the Universe," which explored the implications of the Hopi verb system with regard to the Hopi conception of space and time.
    Whorf is probably best known for his article, "The Relation of Habitual Thought and Behavior to Language," and for the throe articles which appeared in 1941 in the Technology Review.
    In these articles, he proposed what he called the principle of "linguistic relativity," which states, at least as a hypothesis, that the grammar of a man’s language influences the manner in which he understands reality and behaves with respect to it.     Since the theory did not emerge until after Whorf had begun to study with Sapir, and since Sapir had most certainly shared in the development of the idea, it came to be called the Sapir-Whorf Hypothesis.
