Radical Non-Configurationality without Shuffle Operators: An Analysis of Wambaya

The word order facts of radically non-configurational languages pose a challenge to HPSG approaches which assume both that the surface order of words is the yield of the (tectogrammatical) tree and standard HPSG-style cancellation of valence lists. These languages allow discontinuous noun phrases, in which modifiers appear separated from their head nouns by ar-bitrarily many other words from the same clause. In this paper, I explore an analysis which preserves tectogrammatical-phenogrammatical equivalence, and accounts for the word order facts of Wambaya with an analysis based on non-cancellation. This analysis is contrasted with other approaches to discontinuous constituents and analyses of other phenomena based on non-cancellation. Finally, I explore the implications for current models of seman-tic compositionality.
