Book excerpt: "Aspect is widely present in most Quechuan languages, but it has been summarily treated or even overlooked in most of the existing descriptive grammars. This book changes that situation completely. It contains detailed discussions of the semantics and the use of aspect in its relation to tense, modality, evidentiality, etc., and opens up a wealth of unexpected data. ...The historical chapters are a most welcome addition to the grammatical analysis because they are highly relevant for our understanding of the development of aspect in other Quechuan languages and in the Quechuan family as a whole." - Willem Adelaar, Leiden University "This book addresses what is perhaps the most challenging area in the study of Quechuan languages: the scores of suffixes that occur between the verb root and person-marking inflection. It not only sheds light on one of these languages, South Conchucos Quechua, but it shows us new ways to investigate such complexities. This book will stand as a landmark in the study of Quechua." - David Weber, SIL International
