Word-blindness (8)
I believe the answer is:
dyslexia
'word-blindness' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for dyslexia that I've seen before include "Reading disorder" , "Sexy lad I find with abnormal spelling difficulty" , "Word-blindness" , "Reading complaint" , "Reading impairment" .)
