Paradigm structure influences syntactic behaviour

In this chapter, Belyaev analyses several challenging facts of Ossetic nominal inflection that seem to challenge the traditional understanding of Lexical Sharing in LFG. In particular, case markers in Ossetic may attach to the final adjunct of coordinate phrases, even though the structure of the paradigm precludes their analyses as clitics. Moreover, the syntactic behaviour of Ossetic case forms seems to be influenced by paradigm structure: words where the genitive is suppletive and acts as an oblique stem use the genitive instead of the nominative in non-final conjuncts. Belyaev argues that these difficulties can be resolved if the architecture of LFG is extended by Lexical Sharing, which allows one word to occupy two or more syntactic heads. He proposes a formal mechanism of integrating Lexical Sharing with the morphology2013syntax interface of LFG, with Paradigm Function Morphology as the basis for the morphological component.

Copy constructions and their interaction with the copula in Korean

We argue here for a lexicalist analysis of the Korean copula (following Kim, Sells and Wescoat (2004)), on the basis of different properties of sequences of noun-plus-copula, which shows word-like behavior, in contrast to noun and negative copula, which are independent syntactic units. The interactions of these items with various copy constructions brings out their clear differences. The analysis is formalized in HPSG using Lexical Sharing, from Wescoat (2002).

Tongan noun incorporation: Lexical sharing or argument inheritance

As has been shown in other Polynesian languages, in Tongan, adnominal elements can modify incorporated nouns in the noun incorporation construction. Two analysis are considered in this paper for understanding this construction within HPSG. The first, lexical sharing (Kim and Sells, this volume), views the verbs that include incorporated nouns as being single words corresponding to two syntactic atoms. However, this analysis makes incorrect predictions on the transitivity of incorporation clauses. A second analysis, extending Malouf (1999), views these words as verbs, but with some of the combinatorial properties of nouns. This offers both a better account of the data, and preserves the more restrictive theory of the morphology-syntax interface.
