Indo-European is the most recent common ancestor to the largest group of modern languages. From India to Britain and the Americas, the descendants of this mother tongue are still spoken and evolving. In ancient times, the Indo-European languages were similarly diverse, being composed of several branches that spanned over Asia and Europe. These were the Anatolian, Indo-Iranian, Greek, Italic, Celtic, Germanic, and Armenian branches. The Tocharian, Balto-Slavic, and Albanian branches are only attested too recently to be considered ancient language groups.
