Definition
The 'spine' is the row of bones down the middle of your back, supporting your body. It can also mean something resembling this shape, like the backbone of a book or a hard, pointed part of a plant or animal.
Usage & Nuances
Usually refers to the body part in medical or everyday contexts, but also commonly used for the edge of a book ('the spine of the book') and sharp plant/animal parts. Informal use may mean courage ('has spine'). Be careful not to confuse with just 'bone' or 'vertebra'.
