 The grammatical cases are ergative and absolutive, and the semantic cases include instrumental (using), allative (towards), ablative (from), locative (at), comitative (with, having), privative (without, lacking), temporal (at the time of) and semblative (resembling).The dative case can be either grammatical or semantic, depending on the syntactic requirements of the verb.Demonstratives are similarly considered nominals in Wagiman, and take the same case suffixes depending on their semantic and syntactic roles; their function within the sentence.
