"correct accpted spelling"
Spell check accepts "didgeridoo" but not the other one. (rejected "accpted" too) Just having some fun with you, Muttley.
Keep in mind that the Australian Aboriginals had not evolved much past the "Stone Age" prior to their exposure to modern society. That is not meant as a put down. There was just little need for further evolution given their lifestyle, climate and available food supply.
As such, I would imagine that they are in a constant state of flux, right now and this will lead to many instances of mispronunciations, misspellings and so on. More importantly, many of the traditions which have been lost or have lost their meanings will be gone for eternity. I wouldn't get too hung up on spelling when you consider that they didn't have this alphabet.
Having said all that: It is always good to see someone take a real interest in the indigenous traditions. We owe them much on many continents.
