Wagaya belongs to the
Warluwarric (Ngarna) subgroup of the
Pama–Nyungan family of
Australian languages. It is most related to
Yindjilandji,
Bularnu, and
Warluwarra. Gavan Breen groups Wagaya together with Yindjilandji into the "Ngarru" group, while Bularnu and Warluwarra form the "Thawa" group (each respectively after the common word for 'man, Aboriginal person'). These two groups together form the southern branch of Ngarna/Warluwarric, to which the discontinuous
Yanyuwa is related at the uppermost level of the whole subgroup. Work on proto-Warluwarric has been done by Catherine Koch (1989), Daniel Brammall (1991), Margaret Carew (1993), and Gavan Breen (2004). ==Sounds==
