Papua New Guinea (PNG) is the most linguistically complex nation in the world with over 800 languages among multiple language families and language isolates. SIL has been carrying out linguistic research in cooperation with the PNG Department of Education since 1956. Check out the research results of SIL PNG here at the PNG Languages Website. New resources are always being added, including unpublished hard-to-find print materials from as far back as the 1960s.
The maps on this site illustrate the great language diversity in Papua New Guinea shown against a very basic topographic color pattern.
