<DIV><DIV>This book broadens the scope of Eurasian language research, providing a cross-linguistic description and construction-based treatment of a neglected subtype of prenominal relative clause construction. Documenting these constructions contributes to a comprehensive taxonomy of relative clause types, while their particular properties present instructive challenges to linguistic theory. The authors develop a construction-based proposal using default multiple inheritance hierarchy architecture, arguing that these data contribute to the growing evidence for the need to posit constructions as explanatory concepts in grammatical theory.</DIV>
