A Minimalist Account of Null Arguments in Maybrat

This dissertation presents a minimalist account of null arguments in Maybrat. Different generative theories have been put forward for conditions that trigger the appearance of null subjects in a number of languages. There have been two general lines of position since Perlmutter's initial identification of null subjects in some European languages. The first posits that null subjects (pro) appear in languages with a rich agreement paradigm, known as the rich agreement hypothesis. The second argues that rich agreement is not attested in other languages. It suggests that discourse context triggers the appearance of null pronouns. This study was based on the descriptive analysis of 18 stories gathered from the fieldwork and corpus of Maybrat spoken texts. It claims that the two approaches may not fully explain the appearance of null arguments in Maybrat for three respects. First, the null subjects appear in the clauses that both have agreement and no agreement. Second, not all verbs with agreement markers are fully specified in person, number, or gender features (φ-features). Third, objects are also dropped freely in many contexts despite the lack of agreement. Building on the minimalist framework of Agree, the dissertation proposes the derivation of pro in two ways. First, the Tense (T) head is strong in φ-features and pro is a Determiner Phrase (DP). They participate in a local Agree relation. Second, pro is weak in definite feature (D-feature) and the functional head T is deficient for lacking φ-features. The Agree relation can operate if T inherits the features from the Complementizer (C) head. Thus, a long-distance Agree between C and pro is assumed. This dissertation concludes that the appearance of null arguments in Maybrat is licensed either by the agreement head, the discourse context, or a combination of the two conditions. However, among the three conditions, discourse context plays a significant role in promoting the null arguments since pro appears regardless of the verbal agreement inflections. For this reason, this dissertation also proposes that Maybrat may be classified as a radical pro-drop language.
