Barngala is a member of the Thura-Yura L63 sub-group of Pama-Nyungan. Other members include Kaurna L3; Ngadjuri L5; Nukunu L4; Narangga L1; Adnyamathanha L10; Kuyani L9; Nauo L2 and Wirangu C1, which exhibits some differences with the Thura-Yura languages. One particular cultural-linguistic feature uniquely Thura-Yura is the use of ten birth-order names. Another are the regular pronoun forms unique to the sub-group (Simpson & Hercus 2004:179).
