the.com/rib
a curved bone playing bodyguard to your most important organs.
means One of the curved bones that arc from your spine around your chest, forming a protective cage for your heart and lungs.
from From Old English 'ribb,' tracing back to a Proto-Germanic root (compare German 'Rippe' and Dutch 'rib'), all likely springing from a Proto-Indo-European root meaning something like 'cover' or 'roof' — fitting, since ribs roof over your vital organs. The same root may be a cousin of words for arching and covering across the language family.
