The Chalcolithic (English: /ˌkælkəˈlɪθɪk/),[1] a name derived from the Greek: χαλκός khalkós, "copper" and from λίθος líthos, "stone"[1] or Copper Age,[1] also known as the Eneolithic[1] or Aeneolithic[2] (from Latin  aeneus "of copper") is an  archaeological period which researchers usually regard as part of the broader Neolithic (although scholars originally defined it as a transition between the Neolithic and the Bronze Age). In the context of Eastern Europe, archaeologists often prefer the term "Eneolithic" to "Chalcolithic" or other alternatives.
