This book investigates the properties of determiners in Skwxwu7mesh (Squamish) Salish. Determiners in Skwxwu7mesh are shown to behave significantly differently from the definite determiner the in English, as Skwxwu7mesh lacks a definite/indefiniteness distinction. All Skwxwu7mesh DPs can be used in both familiar and novel contexts, and are not required to refer to a unique entity. Instead, Skwxwu7mesh determiners are split along deictic/non-deicticlines. Determiners can therefore vary in terms of their semantics. However, determiners are argued to universally encode contextual sensitivity (domain restriction). A strict correlation between the syntax and semantics of determiners is proposed: if an article occupies D, it is context sensitive. Conversely, articles that do not occupy D are not context sensitive. This book also explores determiner systems in other Salish languages. Deixis is a part of most of the Salish determiner systems, but the systems vary quite a bit from one another. Other languages discussed include Inuttut (Labrador Inuktitut), Lithuanian and Maori.
