There is no single Aboriginal language as there are many different indigenous languages spoken across Australia. Some examples of greetings in different Aboriginal languages are "Kaya" in Noongar, "Yamma" in Gamilaraay, and "Ngeya ngeya" in Warlpiri.
In various Aboriginal languages, greetings can differ significantly. For example, in Yolŋu Matha, you might say "Ninuku, nganana Luke" which translates to "Hello, my name is Luke." It's important to note that there are many Aboriginal languages across Australia, so the exact translation can vary based on the specific language group or region.
