Sapir-Whorf Hypothesis

The principle of linguistic relativity holds that the structure of a language affects the ways in which its respective speakers conceptualize their world, i.e. their world view, or otherwise influences their cognitive processes. Popularly known as the Sapir–Whorf hypothesis, or Whorfianism, the principle is often defined to include two versions:

Strong version: that language determines thought and that linguistic categories limit and determine cognitive categories
Weak version: that linguistic categories and usage influence thought and certain kinds of non-linguistic behaviour.
