Hi John,

many thanks for your reply.

Sorry for not having answered before, but your reply was Greek to me (no 
doubt, due to my own ignorance ;-)).

What I don't understand why polyglossia is problematic when hyphenating 
ancient Greek with LetterSpace.

Pure XeTeX is totally foreign to me and I would need to use LetterSpace 
in a number of documents.

Is there no way to solve this?

Thanks for your help,
