Lagaw Ya had the highest number of 'unique' (that is, non-Pama-Nyungan) forms of any Australian language in their sample. Oral tradition and cultural evidence recorded by and , backed by archaeological evidence and linguistic evidence, shows that Austronesian trade and settlement in South-West Papua, Torres Strait and Cape York occurred; the languages have significant Austronesian vocabulary content, including items such as the following: Some of the Austronesian content is clearly South-East Papuan Austronesian: The linguistic history of the Torres Strait area is complex, and interaction of well over 2500 years has led to many layers of relationship between the local languages, including many words that are obviously common, such as the following 'trade' words in Torres Strait area languages. However, the question of external relationships of Kalaw Lagaw Ya is also complicated by resemblances between both the Paman (Pama-Nyungan, Australian languages) and the Trans-Fly (Papuan) languages. Though few, these may be significant, and include forms such as those noted below, not all of which appear in Kalaw Lagaw Ya. Such resemblances could point to a deep-level relationship dating back to before the flooding of Torres Strait at the end of the last age, as claimed by Mitchell , or they could point to genetic inheritance and subsequent language contact, as discussed by Alpher, Bowern, and O'Grady 2009. Personal pronouns A comparison of the Kalaw Lagaw Ya, Meriam Mìr, Kiwai and Uradhi personal pronouns show similarities and differences in typology. In comparison to Uradhi, Kalaw Lagaw Ya has an archaic typology — or, rather, Uradhi has innovated, having lost the Common Australian 1, 2 and 3 plurals. Kiwai does not have 1–2 pronouns, while Meriam Mìr does not have a dual and trial/paucal set of pronouns which correspond to its verb system. The Kalaw Lagaw Ya system, like that of Uradhi, is Australian: Note that except for Meriam Mìr, the Trans Fly languages also have two-gender masculine-feminine systems, though not marked on the pronouns themselves. However, even though the system has no real surprises for Australian linguistics, it is clear that Kalaw Lagaw Ya has innovated in the 1st and 2nd pronouns, which have the following CA origins: CA *ngali 'we, inclusive' > ngœy [stem: ngœlmu- (old style singing ngalimu-, ngalemu-), ngœimu-] 'we, exclusive'; and with stem extensions ngalpa 'you and I/we' (old-style singing ngalipa/ngalepa), ngalbai/ngalbe 'we (exclusive)', (old style singing ngalebai/ngalibai) CA *ngana+pulV 'we, exclusive dual' > ngœba 'you and
