Noun Phrase or Compound Noun? An Investigation of N + A and N + N Boundary Cases in Persian

Abstract

The present study seeks to investigate the demarcation between noun phrases (NPs) and compound nouns (CNs) in Persian at the syntax-morphology interface. This objective is accomplished through the examination of two most complex nominal patterns, viz. N + A, N + N, with special focus on boundary cases, i.e. the intermediate constructs which possess some properties of both NPs and CNs simultaneously and thus demonstrate contradictory reactions to the various NP-CN demarcation criteria. The results indicate that boundary cases ensue from partial syntactic erosion of NPs through pure lexicalization, whereby NPs turn into CNs without center-switching or category change. This study also shows that almost all boundary cases have no potential for syntactic modification of their elements. It is further demonstrated that N + A and N + N boundary cases are endocentric, head-initial constructs with optional or obligatory internal inflection as well as Ezafe. Syntactic modifiability is also introduced as the most efficient NP-CN demarcation criterion in Persian since it is the first property lost in NP lexicalization process.
