Other forms: cemented, cementing, cements
Cement is the grey powder that binds sand and stone together. Add water and it sets hard.
It is not the same as concrete, which is the finished material made by mixing cement with sand, gravel and water, and confusing the two irritates builders. Mortar is the version used between bricks. The verb has a strong figurative use, since cementing a relationship or cementing your place in a team means making it permanent. The industry is one of the largest sources of carbon dioxide in the world.
Cement was rubble first. Latin caementum meant the chips of stone hewn from a block, from caedō, to cut, which is the same verb standing behind decide. The name moved from the broken bits to the stuff that binds them.
