noun
pellet
PEL-it/ˈpelɪt/
A small rounded or compressed piece of material.
Each wood pellet compresses loose sawdust into a small rounded piece.

Etymology
Pelote meant “small ball,” and English used pellet for little balls of medicine, food, or metal. The modern sense retains that rounded shape while allowing many kinds of compressed material.
