TED-Ed: What do all languages have in common? | Cameron Morin

The video explores Noam Chomsky's theory of universal grammar, which suggests that all languages share innate grammatical rules. It discusses the development of generative syntax and the challenges in identifying universal grammar rules due to language variability. Chomsky's revised theory of principles and parameters is introduced, highlighting shared grammatical principles with varying applications. The concept of recursion as a universal principle is examined, along with the debate on whether language faculty is innate. The video concludes with the impact of these theories on linguistics and cognitive science.

How did Chomsky's hypothesis of principles and parameters attempt to accommodate language variation?
