BARTOC.org: Glottolog Classification (original) (raw)

"Languages are classified (...) into 243 families and 189 isolates, i.e., one-member families. This classification is the best guess by the Glottolog editors and the classification principles are described (...). Users should be aware that for many groups of languages, there is little available historical-comparative research, so the classifications are subject to change as scholarship and interest in those languages increase."
