Indo-European is the largest language family by number of speakers, comprising most of the languages of Europe together with a broad band running through Iran and South Asia. Its branches include Germanic, Romance, Slavic, Celtic, Indo-Iranian, Hellenic, Baltic, Armenian and Albanian, along with extinct branches such as Anatolian (Hittite) and Tocharian. The family was recognized in the late eighteenth century when Sanskrit, Greek and Latin were shown to share systematic correspondences too regular to be coincidence, founding the comparative method that historical linguistics still uses. Whether Anatolian split off before or alongside the rest of the family, the Indo-Hittite question, remains debated among specialists.

Proto-Indo-European is the reconstructed common ancestor of the Indo-European family, not a coordinate daughter classified alongside its member languages; recorded as associated rather than holds because this atlas has no dedicated ancestor-of relation type yet.
