According to a study at an English University, it doesn't matter in what order the letters in a word are, the only important thing is that the first and last letter be at the right place. The rest can be a total mess and you can still read it without problem. This is because the human mind does not read every letter by itself but the word as a whole.
Spelling and the letters in a word: What our brain does, while we are reading, is already amazingly, even if the statement of the freely invented study is generally wrong (although with a pellet of truth), according to the analysis of a scientist (Matt Davis, of the center for language, speech, and brain MRC Cognition and Brain Sciences Unit - Cambridge University). There there is also the text in approximately 15 further languages.
