Punic, as a noun, was the Phoenician dialect of ancient Carthage.
As
an adjective, Punic refers to anything of, or relating to, Carthage or
the Carthaginians. If, for example, there was a pub owned or
predominantly frequented by
Carthaginians, you would refer to it as a Punic pub.
This also helps to understand who was involved in the
Punic
Wars.
In AD 439, the
Vandals
made Carthage their headquarters.
