A piece of metal that flies off an explosive device and injures a soldier is an example of shrapnel.
The dog did not eat my sandwich. It was in a bag. If he had eaten my sandwich, there'd be shrapnel all over the place from him tearing open the bag.
Origin of shrapnel
- After Henry Shrapnel (1761–1842), British army officer
From American Heritage Dictionary of the English Language, 5th Edition
- From Henry Shrapnel, British army officer who invented an anti-personnel shell that transported a large number of bullets to the target before releasing them, at a far greater distance than rifles could fire the bullets individually. The surname is likely a metathesised form of Charbonnel, a diminutive of Old French "charbon" (charcoal) in reference to hair colour, complexion, or the like.
