Literally: wordlessness

The story of the word

Nineteenth-century neurology called it word blindness before reaching for Greek. In 1892 Déjerine described a patient who could still write fluently and then could not read back what he had just written, which located the damage in the pathway rather than the intelligence. The girl's name Alexia is unconnected: it comes from ἀλέξειν, to defend, the same root as Alexander.
