Final answer:
The Sapir-Whorf hypothesis originally proposed that language determines thought, but research suggests that language influences rather than completely controls thinking; the dynamic nature of language supports this view of influence.
Step-by-step explanation:
The question addresses the concept of linguistic relativity or the Sapir-Whorf hypothesis, which posits that the language a person speaks influences their perception of reality and cognition. The statement 'Language dynamism disproves tight control of language on thinking' appears to reference the debate over linguistic determinism versus linguistic influence. While the original strong version of the Sapir-Whorf hypothesis suggested that language determines thought, this has been challenged by subsequent research indicating that language influences rather than strictly determines thinking. Hence, the dynamic nature of language and its evolving quality do suggest that it shapes thought, but does not exert absolute control over it, aligning with the findings of later researchers who have pointed out a lack of empiricism in the strongest claims of linguistic determinism.
