Indo-European: Celtic Branch

The Celtic branch of Indo-European divides into Insular Celtic, today surviving as Irish, Scottish Gaelic and Welsh and further split into the Goidelic and Brittonic sub-branches, and the entirely extinct Continental Celtic languages once spoken across much of pre-Roman Europe. This child group, under Indo-European Branches, holds every Eurasian Language Families member whose sourced description identifies it as Celtic, Goidelic, Brittonic, Insular Celtic or Continental Celtic.
