dyslexia

Learned borrowing from French dyslexie and/or German Dyslexie, coined by German ophthalmologist Rudolf Berlin in 1887, from dys- +‎ lexis +‎ -ia, from Ancient Greek δυσ- (dus-) + λέξις (léxis, “diction”, “word”), from Ancient Greek λέγω (légō, “to speak”), ultimately from Proto-Indo-European *leg- (“to collect, gather; to speak”). The term was coined with λέξις (léxis) being taken to mean "reading," likely due to semantic conflation of Greek λέγω (légō, “to speak”) and Latin legō (“to read”). By surface analysis, dys +‎ lex(is) +‎ -ia.
