 Nominal morphology is significantly less complex than that of the verb.There are a number of case suffixes, denoting ergative, absolutive, dative, allative, locative, ablative, semblative, temporal, instrumental and so on.Apart from the grammatical cases, ergative and absolutive, which are necessary to construct meaningful sentences, an entire range of semantic cases occur with very high frequency, even when their meaning can be expressed without using case.
