This book offers the first comparative discussion of variation in selected areas of structure in the dialects of Kurdish. The contributions draw on data collected as part of the project on Structural and Typological Variation in Kurdish and stored in the Manchester Database of Kurdish Dialects online resource, as well as on additional data sources. The chapters address issues in lexicon, phonology, and morpho-syntax including nominal case, tense and aspect categories, pronominal clitics, adpositions, word order (with special reference to post-predicate constituents) and connectivity and complex clauses. The materials that inform the analysis consist of a systematic questionnaire-based elicitation covering key features of variation in lexicon
