This book takes Korean as a basis to provide a detailed universal Determiner Phrase (DP) structure. Adnominal adjectival expressions are apparently optional noun dependents but their syntax and semantics have been shown to provide an important window on the internal structure of DP. By carefully examining data from Korean, an understudied language, as well as from other unrelated languages, the book provides a broad perspective on the phenomenon of noun modification and its cross-linguistic variations. Furthermore, it offers not only a thorough syntactic analysis but also a formal semantic analysis of noun modifiers that extends beyond a single language. This book will be of great interest to researchers interested in theoretical syntax, its interfaces with semantics, pragmatics, linguistic typology, and language variation.
