V is for Verdigris
Verdigris is the blue-green patina formed on copper, brass or bronze when it is exposed to air or water for a long time.
The word derives from the Old French phrase verte grez, meaning green of Greece. Why Greece? Actually, that's not clear. It could be because verdigris was used as a pigment by artists and so would presumably have been employed by Greek painters in antiquity. Or perhaps not.
Still, it's a nice word. Hard to imagine a gothic novel without it ...
