is a problem with language (with speech sounds being normal).
Wernicke and broca's areas are regions of the brain where damage results in aphasia. Wernicke's aphasia, described as 'word salad', many words not making sense, while broca's aphasia is described as 'telegraphic', few words only. Aphasia can be 'expressive' for language output, or receptive. Google the names for brain maps.
