Adithinngithigh language

Adithinngithigh, or Adetingiti, is an extinct Australian aboriginal language once spoken in Cape York in Queensland.

There has been some confusion over the name:

Given that Aditinngithigh and ‘Arritinngithigh’ seem to have been identified with only one estate each and the names are so similar, it might be tempting to consider their distinct spellings a mere artifact of the recording process, but the names are indeed distinct and moreover the relevant estate are noncontiguous and owned by different people.

However, it is not clear how distinct the two varieties are.
