Since Cora is a language on the verge of extinction, this research monograph is undoubtedly the last chance of reading a thorough analysis of the emergence of its grammaticalized locative forms, coupled with a comprehensive account of the extensions from the locative domain to the domain of time. Having spent many years doing fieldwork among Cora speakers, E. Casad occupied the best possible position to undertake this endeavor and to complete it successfully. I know of nobody else who could have done it or would still be able to do it.Nicole Delbecque, Katholieke Univ
