Why is Cyprus called Cyprus?

There are various explanations for that, but, the more possible one is that it took the name out of Kuprum, which meant Copper in the ancient era of Cyprus. And as the island was popular for the wealth amounts of Copper (which keeps until today), they used to call it the copper land, otherwise Kuprum. Through the ages the name had been alternated to several other between which Kubrus, and, ended to Cyprus (in Greek is Kypros).
