The affixal nature of the definite article in Hebrew Shuly Wintner Seminar fuer Sprachwissenschaft Universitaet Tuebingen Kl. Wilhelmstr. 113 72074 Tuebingen, Germany shuly@sfs.nphil.uni-tuebingen.de This paper provides evidence for the affixal nature of the Hebrew definite article, `ha'. Usually considered a stand-alone word or a clitic, the rules that govern the combination of the article with nominals are viewed as part of the syntax. This paper suggests an alternative analysis by which it is attached to its host nominals through a morphological process. Several arguments, from all levels of linguistic representation, are provided. First, accepted criteria for wordhood reveal the clear dependent behavior of the definite article. Then, its affixal characteristics are discussed: phonological, morphological, syntactic and semantic considerations support such a view. Furthermore, it is shown that treatment of the definite article as an affix facilitates the construction of both syntactic and semantic theories for Hebrew. In the framework of Head-Driven Phrase Structure Grammar, a single lexical rule accounts for the combination of the article with various types of nominals. An HPSG grammar for a fragment of Hebrew, focusing on noun phrases, is presented, in which the affixal view of the definite article is integrated.
