 However both languages have a very low cognacy rate (shared vocabulary) of about 10%.Wagiman is also superficially similar to the neighbouring Gunwinyguan languages phonologically (both share a fortis/lenis stop contrast and a phonemic glottal stop) and to the Mirndi language Jaminjung-Ngaliwurru in the use of coverbs.Mark Harvey notes similarities in the verbal inflectional systems between Wagiman and the neighbouring Eastern Daly languages.
