Well, your sincere interest didn`t make it through then.
Viewing the remarks, you`ve made within this thread, your interest in the subject has had the dictinct mark of your main interest being how all this relates to your kids.
Seems to me your interest is just that  

(Note : I have  negative experiences about `moms  ` being oh so fascinated  by something ` -  they never really are .
They soon  reveal  themselves as chattering  `NT pain in the ***`  - worse than anything you can imagine among your `NT peers `
Be aware  :  What`s in  this  bracket is  based on my personal live encounter with the fiercely presenting themselves as moms segment - and not pointing directly at you.  )
  
  
As to your other remark.
The point  I  was making about hyperlexia and spelling  would narrow the list of relevant languages , as obviously only  languages  written in phonetic  alphabets would be of interest  here.    

And of course the languages matching that criteria  can be rated according  to the advantages they may or may not  present to people who are  hyperlexic
It would be immense fun to do  the list,  by the way.

Without having to do much research, I would register French as a language  marked by the  crucial  discrepance between pronounciation and spelling, and thereby  making hyperlexics the natural born winners .
