Suffixaufnahme (ˈzʊfɪksˌaʊfˌnaːmə, "suffix resumption"), also known as case stacking, is a linguistic phenomenon used in forming a genitive construction, whereby prototypically a genitive noun agrees with its head noun. The term Suffixaufnahme itself is literally translated as "taking up of suffixes", which can be interpreted as the identical case marking of different but referentially-related phrases, with the presumption that nominal phrases possess a flat or non-configurational syntax. Across syntactic theories, case is seen as a bundle of features, and case agreement as the identity of case features. It was first recognized in Old Georgian and some other Caucasian and ancient Middle Eastern languages as well as many Australian languages, and almost invariably coincides with agglutinativity. The usage of case stacking is not limited to genitive constructions, although the genitive case is involved in the majority of occurrences across languages. Cross-linguistic variations in case stacking representation and functions can be found. In general, case-stacking describes the phenomenon whereby a single word may bear multiple cases reflecting its relation to a number of different syntactic elements. It is important in the development of theories of inflectional morphology and the establishment of the relation between morphology and syntax. In Kayardild, the combination of adnominal cases (ablative and genitive) in possessor-like functions, and various relational and adverbial (e.g., spatial) cases is common. Case functions may be combined where ablative functions similar to a genitive adnominal case, and the instrumental case is applied to the entire NP, as seen in the following example : From this example, all words of the relevant phrase share the case marking which is assigned to the phrase as a whole, namely, the instrumental case. This follows Evans’s (1995) total concord principle, which states that case inflections are distributed over all sub-constituents regardless of the level they are originated from (i.
