Southern Daly is a distant and problematic relationship.
Murrinh-Patha was once thought to be an isolate, due to lexical data: It has, at most, an 11-percent shared vocabulary with any other language against which it has been compared.[1] However, Murrinh-patha and Ngan’gityemerri correspond closely in their verbal inflections. Green (2003) makes a case that the formal correspondences in core morphological sequences of their finite verbs are too similar (in their complexities and their irregularities) to have come about through anything other than a shared genetic legacy from a common parent language.[2] Nonetheless, lexically they have almost nothing in common, other than cognates in their words for 'thou' (nhinhi and nyinyi) and 'this' (kanhi and kinyi),[3] and it is not clear what could explain this discrepancy.

^Note that Ngan’gityemerri has no nh, and so one would expect it to have ny where its relatives have nh.
