In Korean, the ordering of NP constituents is known to be quite flexible, but few attempts have been made to provide their precise syntactic structures. This chapter reviews the distributional properties of Korean prenominal expressions as well as relevant ordering constraints, and then offers a surface-oriented analysis of Korean NP structures. This surface-oriented, construction-based analysis, tightly interacting with lexical information, can not only capture the flexible orderings of prenominal expressions in a simple manner but also generate proper and precise NP structures.
