Indo-European Nominal Morphology:The Decads and the Caland System
Rau, Jeremy. 2009. Indo-European Nominal Morphology:The Decads and the Caland System. Innsbruck: Innsbrucker Beitr. zur Sprachwiss. Publisher's VersionAbstract

The following book presents two self-standing studies on IE nominal morphology that seek to expand the results of what we have learned in the last forty years and to map out new directions for future research. The first study tackles a long-standing crux in the system of the IE numerals, the original inflection behavior and derivational interrelations of the IE decad formulations. The second study focuses on a broader question in IE nominal morphology and investigates a phenomenon that has taxed the imagination of scholars for more than a century, the Caland system.
