The typological, contrastive, and descriptive studies in this volume investigate the strategies employed by the world's languages to create complex denotations by combining two noun-like elements, together with the kinds of semantic relation they involve, and their acquisition by children. The term 'binominal lexeme' is employed to cover both noun-noun compounds and a range of other naming strategies, including prepositional compounds, relational compounds, construct forms, genitival constructions, and more. Overall, the volume suggests a new, cross-linguistic approach to the study of complex lexeme formation that cuts across the traditional boundaries between syntax, morphology, and lexicon.
