spine's
Back bone's characteristic
Spine's is the possessive form of spine—the column of vertebrae running down the back, or the stiff strip forming a book's bound edge.
The word typically appears when attributing something to the spine: the spine's curvature, the spine's flexibility, the book's spine's lettering had faded.
Figuratively, spine means courage or resolve, so the spine's strength might refer to either physical structure or moral backbone.
