Sapir-Whorf Hypothesis is a hypothesis concerning the role of the language we speak, in which we determine the form and character of the world we inhabit.
Most people accept that the world is just here, apart from the language and other systems of representation we use. Edward Sapir and Benjamin Wharf tested this position by pointing out that the world we inhabit exists largely because of the language we use. The world is not just here, but always through the symbolization of language is subjected to learning and determination with the help of other culturally inherited systems of representation.
