Dyslexia is concerned with spelling and reading the written word, not misunderstanding the spoken word.

Hmmmm. Dyslexia as she is described medically is about the difficulty of ordering the letters in a word. Though letter substitutions would be included. The way the eye moves is implicated, as a symptom and a means of understanding.

BUT

the dictionary definition doesn't define what comes with dyslexia. Those things are unique to each individual but they are there. My ex-wife had the textual problem, she also found it difficult to pronounce Knarsborough, and Dursley. They represented bogey combination for her. She also was ambidextrous (a clue) and her speech was pretty low on voiced phonemes, probably due to being brought-up with a night-worker dad sleeping in the day, she had to whisper while learning to speak. She misunderstood the connection between reading and speaking, even if she heard it dozens of times. She never reported synaesthesia which is put on the same spectrum by researchers into these things.

Now what caused what and what was inherent is a mystery but like I said - the real problem is a syndrome, each person presents with a subset.

Now how do I e-mail the Dyslexia Society?
