What is the Indo-European roots?

Indo-European roots are an imaginative language created by comparative linguistics. The group of languages spoken in west Ireland, the area from eastern Ireland to India and the area from north Scandinavia to southern Italy are called Indo-Eurorean. Comparative linguists have investigated the similar features of languages in this group. Those languages were found to come from a common ancestry from the investigation, and are called Proto-Indo-European. The language is roughly divided into the 12 groups: Anatolian, Indo-Iranian, Greek(Hellenic), Italic, Celtic, Germanic, Armenian, Tocharian, Balto-Slavic, Albanian, and other branches [see Figure 1]. Indo-European roots is an imaginative language which divides the roots of these languages into several patterns.[2]
