The Waigali language is a member of the Papuan languages, primarily spoken in the Sandaun Province of Papua New Guinea. It is used by the Waigali people, who reside in the region's mountainous areas. The language is part of the diverse linguistic landscape of Papua New Guinea, which is home to over 800 languages. Waigali is primarily an oral language, with limited written resources. Efforts are being made to document and preserve it, as many indigenous languages face the threat of extinction due to globalization and cultural shifts. The preservation of Waigali is important for maintaining the cultural identity of its speakers.
