Crowley uses the dialect name Uradhi as a language and a dialect name in his description of Uradhi (Y184), Yadhaykenu Y8, Angkamuthi Y7 and Atampaya Y183 dialects (1983:308). Other local groups he identifies (using a practical orthography based on Crowley's phonetic script) are Wuthathi Y10, Mutyanthi Y187, Yaraytyana Y231, Yumukuntyi Y190 and Utyangikwathiya Y194, Yatay Y232 and Uradhi.
Injinoo Ikya Y238 (Injinoo Speak) is the language name used to describe three language varieties Angkamuthi Y7, Atambaya Y183 and Yadhaykanu Y8 by the community, and their language revitalisation project is Injinoo Ikya - Angkamuthi //pamalanguagecentre.org.au/injinoo-ikya-angkamuthi/>.
Crowely's map of Uradhi dialect locates it east of the coast strip to the north of Port Musgrove (Angkamuthi country) incorporating the mouth of the Ducie River, the lower reaches of the Dulhunty River and the upper reaches of the Skardon River in the north; on the western side of Cape York Peninsula (1983:306, 308, 311).
Speaker numbers were measured differently across the censuses and various other sources listed in AUSTLANG. You are encouraged to refer to the sources.
Speaker numbers for ‘NILS 2004’ and ‘2005 estimate’ come from 'Table F.3: Numbers of speakers of Australian Indigenous languages (various surveys)' in 'Appendix F NILS endangerment and absolute number results' in McConvell, Marmion and McNicol 2005, pages 198-230 (PDF, 2.5MB).
