Obliques: Some that are, and some that aren’t
This study first provides a general survey of formal and semantic properties of elements expressing location, direction, means, instrument, manner, accompaniment, benefactee and association, etc. realized in Cora, an Uto-Aztecan language, as free postpositional forms or, less prototypically, as locative verbal prefixes or a combination of both types. A detailed analysis is then given of the various meanings of six specific free form postpositions and of their extended variants. For each of these highly polysemous postpositions, a schematic network structure is provided which accommodates the variety of meanings they are able to convey. Each schematic network is further shown to be related to one, two or three prototypes, to which the non-prototypical variants are related through elaboration or extension.
