The 'backbone' is the main support structure of the human body, also known as the spine or vertebral column 🦴. It's a column of bones that runs from the skull to the pelvis, protecting the spinal cord and supporting the body's weight. Metaphorically, 'backbone' refers to strength of character or resolve. Someone with backbone is courageous and determined. It's both a literal and figurative term. Without it, you'd crumble.
