In Australia it is quite common to talk about Aboriginal people as they feature quite often when talking about sports, Olympics or politics.
The word that is used to describe Aboriginal people by native Chinese speakers is 土著人. I have had someone tell me (and I can't remember if it was a native Chinese person or not) that the word wasn't very flattering.
What does 土著 mean, why was it chosen to mean an Aboriginal person and does it have negative connotations?
