Kalaw Lagaw Ya is thus a mixed language in that a significant part of its lexicon, phonology and grammar is not Australian in origin. The core nominal, pronominal and verb morphology is Australian in both form and grammar — though a certain amount of the grammar is common to Trans-Fly and Paman languages in the first place. Some semantic categories, verb number morphology, and some other morphology are non-Australian in origin. Potentially 80% of its vocabulary is non-Australian. The interplay of the above within the subsystems of Kalaw Lagaw Ya lexicon, phonology and grammar points more to mixing through shift and borrowing rather than pidginisation and creolisation.
