Thank you very much...it is a lot of info. Sorry if I bothered with this curiosity, but the more I study the language the more I get curious about the story of some words. I already know I will end up buying some book about classic Japanese
The most I had got about ます was that it meant to give and that in time it changed from まらするー＞まるするー＞まっするー＞まっす・まする ー＞ます So as you can see you got more info than I was able to
You rock as always.
