Language is a defining characteristic of humans, playing a crucial role in both species evolution and individual development. While traditional views, such as Chomsky's, emphasize language's dual functions in sensorimotor externalization and conceptual-intentional thought, its broader role as a modulator of cognitive and neurological systems remains underexplored. Here, we propose that language, due to its profound, accessible, and widespread neurological activation, serves as a pivotal modulator of these systems. This perspective provides new insights into the interconnection between language, cognition, and brain function, and points to novel therapeutic pathways that leverage the modulating capabilities of language for cognitive enhancement and neurological rehabilitation.
