the slow-motion demolition that turned soft rodents into wood's eternal enemy

means To bite at something persistently and gradually, wearing it down little by little — or, figuratively, to nag at the mind the same relentless way.

from From Old English gnagan, to bite or eat away. It belongs to a wider Germanic family — related to Old Norse gnaga and German nagen — and the cluster of words begins with that throat-catching 'gn-' sound, the kind of mouthy, grinding noise these words seem to imitate. English long ago let the 'g' fall silent, but it still sits there on the page like a tooth marks left behind in the wood.
