Definition
Copper is a reddish-brown metal that is used to make wires, pipes, coins, and many other objects. It conducts electricity and heat very well.
Usage & Nuances
Usually an uncountable noun when talking about the metal: 'made of copper', not 'a copper' for the material. Common collocations: 'copper wire', 'copper pipe', 'copper coin'. In some informal varieties of English, 'copper' can also mean a police officer, but that meaning is separate and context-dependent.
