Copper

Hound dog's name

Copper is a reddish-brown metal, soft and highly conductive, used in wiring, plumbing, and coinage.

The color copper describes this distinctive brownish-red hue: copper hair.

A copper is a large metal vessel for boiling, historically made of this metal.

In British and dated American slang, a copper is a police officer—probably from the verb cop meaning to catch.

The coppers are coming.
