aphasia（n.）
在病理学中，"失去说话能力"，特别是由于脑部损伤或疾病，始于1867年，源自现代拉丁语 aphasia，来自希腊语 aphasia "无言"，这是一个抽象名词，来自 a- "无"（参见 a- (3)）+ phasis "发言"，来自 phanai "说话"，与 phēmē "声音，报告，谣言"有关（来自 PIE 词根 *bha- (2) "说话，告诉，说"）。
APHASIA 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.

失语症是最近给失去清晰语言能力的疾病命名的术语，而发音和发音的器官以及智力都没有受损。这种疾病的病理学目前在科学界引起了大量的讨论； 法国科学院在1865年的几次 séances 中专门阐述了这个问题，而法国和我们国家的医学期刊最近也包含了大量关于这个脑病理学中模糊特征的原创内容。[Frederic Bateman, M.D., "Aphasia," London, 1868]
