The left hemisphere of the brain is most commonly associated with language functions due to its essential roles in processing language, speech production, and comprehension. This is supported by extensive research in neuroanatomy and psychology, which has shown that areas such as Broca’s area, involved in speech production, and Wernicke’s area, critical for language comprehension, are predominantly located in the left hemisphere.

While both hemispheres contribute to language and communication to some extent, especially in tasks that require a more holistic or emotional processing of language, the left hemisphere remains the primary area for these functions in most individuals, particularly those who are right-handed, where this lateralization is most pronounced.

Understanding this lateralization is crucial for approaches to language therapy and rehabilitation following brain injuries or strokes, emphasizing the dominance of the left hemisphere in facilitating effective communication.
