The word Dyslexia comes from two Greek words dys meaning impaired and lexis which means language or spelling. But on the contrary people with Dyslexia arent stupid or lazy most actually have a normal or above average mind. Most people think that Dyslexia reverses letters and numbers but really that is just a normal part of growing and are actually seen in many kids until 1st or 2nd grade.
