Giving voice to space: the grammar of Northern Alta spatial roots

Recent cross-linguistic studies on spatial language reveal a great diversity in the way languages encode spatial information. Yet, given that there are not many spatial studies that have systematically targeted languages with a Philippine-type voice system, it is not clear how spatial expression is structured in such languages. The aim of this study is to address this knowledge gap through an in-depth investigation of Northern Alta, a language presenting such a voice system. The study combines data from stimulus-based tasks with a modern documentation corpus of the language and elicited data to examine the linguistic strategies deployed in four different spatial subdomains: location, disposition, orientation, and routes. The results show that each subdomain favors a distinct set of derivational affixes and a particular set of lexical roots. It is argued that the morphological system of the language plays a crucial role in the structuring of spatial expression. It allows roots with spatial meanings such as ‘front’, ‘side’, ‘top’, and ‘back’ to derive a variety of spatial verbs that are key in several spatial domains. The study also shows that Philippine-type languages have important information to contribute to cross-linguistic studies of spatial language.
