According to Vygotsky, how is language viewed?

Vygotsky's theory views language as a critical component of cognitive development and not merely as a tool or instinct. He posited that language is intertwined with thought and plays a pivotal role in the development of higher mental functions. Language is seen as a dynamic and evolving phenomenon that reflects and shapes human thought processes. It is through social interactions that individuals develop language skills, which in turn enhances cognitive development. This perspective highlights the importance of social context and cultural influences in the formation and evolution of both language and thought, making it a developing aspect rather than a static tool or something solely instinctual.
