Receptive aphasia, also known as Wernicke’s aphasia, fluent aphasia, or sensory aphasia, is a type of aphasia in which an individual is unable to understand language in its written or spoken form. Even though they can speak using grammar, syntax, rate, and intonation, they typically have difficulty expressing themselves meaningfully through speech. Receptive aphasia was named after Carl Wernicke who recognized this condition. People with receptive aphasia are typically unaware of how they are speaking and do not realize their speech may lack meaning. This is due to the fact that they have poor comprehension skills and do not understand their own speech. They typically remain unaware of even their most profound language deficits. When experienced with Broca's aphasia the patient displays global aphasia.
