While the Armenian language is classified as an Indo-European language, its placement within the broader Indo-European language family is a matter of debate. Until fairly recently, scholars believed Armenian to be most closely related to Greek and Ancient Macedonian. Eric P. Hamp placed Armenian in the "Pontic Indo-European" (also called Graeco-Armenian or Helleno-Armenian) subgroup of Indo-European languages in his 2012 Indo-European family tree. There are two possible explanations, not mutually exclusive, for a common origin of the Armenian and Greek languages.
