Word History

Etymology

borrowed from French aphasie, from a- a- entry 2 + Greek phásis "utterance, statement" (from pha-, variant stem of phēmí, phánai "to say, speak" + -sis -sis) + French -ie -ia entry 1 — more at ban entry 1

Note: French aphasie was introduced by the physician Armand Trousseau (1801-67) in "De l'aphasie, maladie décrite récemment sous le nom impropre de l'aphémie," Gazette des hôpitaux civils et militaires, tome 37, issue of January 12, 1864, pp. 13-14. As is evident from the title, Trousseau preferred aphasie to the term aphémie, introduced earlier by physician and anthropologist Pierre Paul Broca (1824-80). Broca replied in defense of his coinage in a letter published in the same periodical on January 23. The controversy, with translated extracts from Gazette des hôpitaux, is summarized by John Ryalls in "Where does the term 'aphasia' come from?," Brain and Language, vol. 21 (1984), pp. 358-63. Though Trousseau's arguments are linguistically not at all sound, his choice has nonetheless prevailed.
