Eugene Casad’s posthumous monograph is an in-depth study of the TIME IS SPACE metaphor in Cora – an Uto-Aztecan language spoken in the state of Nayarit, Mexico – within the framework of Ronald Langacker’s Cognitive Grammar. The author provides an introduction to Cora speakers and their history, and traces the evolution of Cora locative expressions, comparing them with cognate or corresponding expressions in other Uto-Aztecan languages, e.g. Huichol, to reconstruct the development of Cora temporal meanings. Based on a meticulous analysis of synchronic and diachronic data, Casad postulates distinct Cora models of time, grammatical aspect, and event structure, among which the topographically based model of time is especially prominent.
