What does "all the more" mean in the following? I cannot find its definition in the dictionary.
How does one go out on top and, all the more, do it with grace?
Here, the context is about a person who is leaving a position.
You could paraphrase it with furthermore or moreover. It is similar to what's more.
He left, and what's more, he left in style.
But to my ear it's a little odd. I haven't really ever heard all the more used in that manner, and cannot recall any book where it was used that way.
When I've heard it used, it was used like this:
When a cool kid at school has such a widget, most kids will want one all the more.
He loved her all the more for her fiery temper.
and there it could be glossed as "even more" or "that much more". Lurking in this locution the more is an ossified instrumental-case comparative that has survived from a time when English was a declined language like its Germanic cousins.
First, the essential meaning of the sentence (if the parenthetical information is removed) is:
How does one go out on top and do it with grace?
In this context, the phrase all the more could be replaced with the following phrases:
How does one go out on top and, furthermore, do it with grace?
How does one to out on top and, more than that, do it with grace?
To rephrase the sentence, it's saying this:
How does one not only go out on top but also do it with grace?
Update: In response to a comment left here, I conducted my own Google search and came up with many references to the expression.
