Aphasia is an inability to comprehend and formulate language because of dysfunction in specific brain regions. Most often caused by a cerebral vascular accident (CVA), which is also known as a stroke, aphasia can cause impairments in speech and language modalities. To be diagnosed with aphasia, a person's speech or language must be significantly impaired in one (or several) of the four communication modalities following acquired brain injury or have significant decline over a short time period (progressive aphasia). The four communication modalities are auditory comprehension, verbal expression, reading and writing, and functional communication.
The difficulties of people with aphasia can range from occasional trouble finding words to losing the ability to speak, read, or write; intelligence, however, is unaffected. Aphasia also affects visual language such as sign language. In contrast, the use of formulaic expressions in everyday communication is often preserved. One prevalent deficit in the aphasias is anomia, which is a deficit in word finding ability.
The term "aphasia" implies that one or more communication modalities have been damaged and are therefore functioning incorrectly. Aphasia does not refer to damage to the brain that results in motor or sensory deficits, as it is not related to speech (which is the verbal aspect of communicating) but rather the individual's language. An individual's "language" is the socially shared set of rules as well as the thought processes that go behind verbalized speech. It is not a result of a more peripheral motor or sensory difficulty, such as paralysis affecting the speech muscles or a general hearing impairment.
Aphasia is from Greek a- ("without") + phásis (φάσις, "speech"). The word aphasia comes from the word ἀφασία aphasia, in Ancient Greek, which means "speechlessness", derived from ἄφατος aphatos, "speechless" from ἀ- a-, "not, un" and φημί phemi, "I speak".

Douglas Harper's Etymology Dictionary
"loss of ability to speak," especially as result of brain injury or disorder, 1867, from Modern Latin aphasia, from Greek aphasia "speechlessness," from a- "without" (see a- (3)) + phasis "utterance," from phanai "to speak," related to pheme "voice, report, rumor" (see fame (n.)).\n\nAPHASIA is the term which has recently been given to the loss of the faculty of articulate language, the organs of phonation and of articulation, as well as the intelligence, being unimpaired. The pathology of this affection is at the present time the subject of much discussion in the scientific world; the French Academy devoted several of their séances during the year 1865 to its special elucidation, and the Medical Journals of France and of our own country have lately contained a good deal of original matter bearing upon this obscure feature in cerebral pathology.
