Hi, Rusty!
I have found the Grammarist site.....yes, it does look intriguing......
I have added it to my Favourites to explore at leisure.
Now "Manon"......
That is interesting about its being a nickname for Madame Roland.
I thought that she was born "Marie -Jeanne"?
Now, do you remember when I was researching "Manon" for Manon Lloyd?
I came across a reference saying that "Manon" was a nickname for "Marie"?
That would follow here, would it not?
That Marie- Jeanne Roland (nee Philippon) should be called "Manon"?
Just a thought.......?
And wasn't it of a somewhat strange coincidence that Marie - Jeanne (Philippon) should marry Jean- Marie (Roland)?
What has happened to your "snowy" clouds?
