Linguistic determinism is the idea that language and its structures limit and determine human knowledge or thought, as well as thought processes such as categorization, memory, and perception. The term implies that people who speak different languages as their mother tongues have different thought processes. Linguistic determinism is the strong form of linguistic relativity (popularly known as the Sapir-Whorf hypothesis), which argues that individuals experience the world based on the structure of the language they habitually use. Though it played a considerable role historically, linguistic determinism is now discredited among mainstream linguists.
