I'm not exactly sure what I've put together here, but let's give it a go
Boast that you know me, I look a bit like a ball
From the end of a wall, I take the greatest of falls
Horses may try, scrape me into a lazy pile
But it takes more than a tail to piece together my wile
So with a sigh, the men they concede, "may as well make the most"
They'll pair me with spice or mix a nice garlic loaf
Not Humpty Dumpty
(I thought it would be cute to model it after Humpty Dumpty but the answer's more abstract)
The second line is the best place to look for the answer, tho the rest (except the 2nd last) hint at it.
The answer is a word but not a thing. Small like an egg but big in spirit. It's carefully hidden in the clues (Except the first line where it's sloppily hidden (really not happy with that line) and the 2nd last line where I just didn't bother).
