Etymology

Origin of dyslexia

First recorded in 1885–90; from New Latin, from Greek dys- dys- + léx(is) “speech, text, word” ( lexis ) + -ia -ia

Explanation

Dyslexia is a reading disorder. People who have dyslexia have trouble matching the sounds in words with the letters and letter combinations that make those sounds. Dyslexia is from the Greek roots dys, "difficult," and lexis, "word." Although dyslexia literally means "difficulty with words," someone who has dyslexia may also have trouble in other areas like math, telling time, or even telling left and right. However, there's no lack of intelligence associated with dyslexia: famous dyslexics include Thomas Edison, John Lennon, and Whoopi Goldberg.
