While it is reasonable to use indigenous words that had/have meaning in the speech of the people who used them, it is ridiculous to apply words for things that did not exist for those people. As an example, would the concept of "stairway" ever have existed until stairways had been introduced by people who made them? I believe that when the first overland explorers reached northern Australia, near the ocean, the local indigines saw the rifles of the explorers and immediately called them 'musquit' or similar. The reason? They had seen the muskets of the Dutch and Malays who came to fish in the area before the British explorers arrived from the South. The explorers would have been carrying rifles.
