original meaning (e.g. Eora)" is discussed at length by the Aboriginal Heritage Office: There is a move away from using words like Eora, Dharug, Guringai among some of those involved but still a sense by others that these words now represent a part of Aboriginal culture in the 21st century. It seems clear that with each new piece of research the issue remains confusing with layer upon layer of interpretation based on the same lack of original information. This is exacerbated where writers make up names for their own problem-solving convenience. In the absence of factual evidence, it seems the temptation to fill the void with something else becomes very strong and this does not appear to be done in consultation with Aboriginal people who then inherit the problem. Language The language spoken by the Eora has, since the time of R. H. Mathews, been called Dharug, which generally refers to what is known as the inland variety, as opposed to the coastal form Iyora (or Eora). It was described as "extremely grateful to the ear, being in many instances expressive and sonorous", by David Collins. It became extinct after the first two generations, and has been partially reconstructed in some general outlines from the many notes made of it by the original colonists, in particular from the notebooks of William Dawes, who picked up the languages spoken by the Eora from his companion Patyegarang. Some of the words of Aboriginal language still in use today are from the Darug (also possibly Tharawal) language and include: dingo=dingu; woomera=wamara; boomerang=combining wamarang and bumarit, two sword-like fighting sticks; corroboree=garabara; wallaby, wombat, waratah, and boobook (owl). The Australian bush term bogey (to bathe) comes from a Port Jackson Dharuk root buugi-.

(son) Country Eora territory, composed of sandstone coastal outcrops and ridges, coves, mangrove swamps, creeks and tidal lagoons, was estimated by Norman Tindale to extend over some , from Port Jackson's northern shores up to the Hawkesbury River plateau's margins, around Pittwater. Its southern borders were as far as Botany Bay and the Georges River. Westwards it extended to Parramatta. In terms of tribal boundaries, the Kuringgai lay to the north: on the Western edges were the
