The Yilba language (and variant names as per the people) is extinct as of 2020[update], with no speakers recorded since before 1975. It is regarded as a dialect of Biri.[2]
Social organisation
The Yilba were composed of kin groups of which six at least are known:[3][2]
While stating that there are six "hordes", Tindale gave the names of only three, two of which differ from the list in one of his primary sources on the six, namely:
