... somewhere between Hermit Hill and Port Keats (Capell 1963 as quoted in Tryon). Between Daly and Moyle Rivers, Knuckey's Lagoon, Bulkanj, Wudi Gapil Diyerr (Green 1989).

Marrithiyel traditional country occupies a large central part of the hinterland between the lower Daly & Moyle Rivers. To the west, on the coast, are Marrithiyel’s sister dialects Marri Tjevin and Marri Ammu, with the Marri Dan dialect to the south. Also to the south are Marri Ngarr, Ngan'gikurunggurr N8 and Marramaninjsji, which is closely related to Marrithiyel. Matngele is then to the east, with the Merranj dialects to the north. The Marrithiyel community have a homelands base in their traditional country at ‘Woodykapildiya’ (Wudi Gapil Diyerr), but also live at Nauiyu and across the greater Darwin region. Only a few fully fluent, elderly speakers of Marrithiyel remain. However, Marrithiyel appears to have once been something of a lingua franca in the Daly, perhaps due to its central location, and there are many part speakers of it to be found across the region (Green & Nordlinger, viewed November 2020).
