 | | The Indo-European language family is attested in twelve branches, some of them extinct, with a historical distribution over most of Europe, Anatolia, Iran, India and parts of Central Asia (East Turkistan). |
 | | The languages are traditionally separated into a Satem group in the east (Baltic, Slavic, Indo-Iranian, Armenian) and a Centum group in the west (Greek, Italic, Celtic, Germanic), according to their different treatment of PIE velar sounds. |
 | | The language group was briefly referred to as "Indo-Germanic", until it became apparent that the group included most of the other languages of Europe, as well. |
