Guwar is the language spoken by the Ngugi (E26) people of Moreton Island. It was previously understood to be an isolate; in 1888 Watkin compared it to the Yagara dialects of North Stradbroke Island and the Moreton Bay coastline, describing Gowar (E26) as 'very distinct'. Jefferies says that Guwar is a language of the Bandjalang E12 sub-group which has been heavily influenced by Yagara, due to the demographic relationships between the Ngugi and their Yagara speaking neighbours, the Guwanpul E19 and the Nunukul E21. The approximate percentages of Guwar lexicon that can be linked to Bundjalung and Yagara are 45% and 25% respectively (Jefferies, p.c. August 2020).
