An ongoing debate in the field of linguistics is whether language is controlled by thought, or thought by language. Edward Sapir and Benjamin Whorf proposed a hypothesis claiming that a person's native language will control their thoughts and that if a concept is not expressed in one's native language, they will not understand this concept. The case of the Hopi tribe is used to back this theory up. Unlike in western languages, Sapir-Whorf suggested that the Hopi tribe have no concept of time, and therefore, couldn't understand the idea of time. Similar cases have been raised such as the case of the Inuit people who have been documented as having a large number of words for different snow, and as we have no words to describe the different types of snow, we cannot physically understand the distinctions or see the distinctions until they are described to us and given a name. However, Noam Chomsky suggests that all people are born with language rules in their brain and that this is universal. Do we think in words? Can we understand concepts for which we have no name? Does our language control our thought?
