the.com/backbone
thirty-three vertebrae stacked into a column that holds you up and signs your spinal cord's mail.
means The column of vertebrae running down the center of your back — and, by extension, the strength of character or essential supporting structure of any system.
from A plain English compound, old and unglamorous: 'back' (Old English bæc) plus 'bone' (Old English bān). The literal sense — the spine — came first; the figurative sense of moral firmness or 'having a backbone' is a later metaphor, leaning on the idea that the spine is what keeps a body upright and unbending. The same image of the spine as a structural keel shows up across languages, which is why we also speak of the 'backbone' of a network or an argument.
