The nature of configurationality in LFG

The central issue in this thesis is configurationality, which has broadly been defined in terms of a division of the world's languages based on their core syntactic structure. Specifically, languages are traditionally divided into so-called configurational and non-configurational languages. Configurational languages are assumed to be languages with many restrictions on word order, and non-configurational languages are assumed to be languages with very few or no word order restrictions. Many linguists posit a strict division between the two different types of languages. In this thesis I propose a non-derivational approach to configurationality, and I discuss in detail three posited characteristics of non-configurational languages (in comparison to configurational languages): free word order, discontinuous expressions and subject-object asymmetries in binding. I propose a four-way classification of languages instead of a two-way one, based on constraints on annotations on phrase structure nodes, both for argument functions and for information structural roles (such as topic and focus). I propose that this four-way distinction is what underlies configurationality. I show that discontinuous expressions and potentially subject-object symmetries follow from the nature of languages that have traditionally been classified as non-configurational. For my analysis I employ Lexical Functional Grammar (LFG), a non-derivational framework which is particularly well-suited to account for languages in which grammatical functions are not tied to specific phrase structural positions, due to its parallel architecture. This characteristic of LFG enables me to provide a straightforward classification of languages, by the ability to separate the influence of grammatical functions and information structural roles on word order and phrase structural configuration.
