The acquisition of Native American languages is an area of study in which there is still muchwork to be done, and this is especially true of Inuit languages. That alone makes ShanleyAllen's Aspects of argument structure acquisition in Inuktitut a welcomeaddition to the list of publications on first language learning. The book is not, however, strictlyintended for those who study Native American language acquisition. The extensive backgroundinformation provided, both theoretical and methodological, makes Allen's work accessibleto linguists with various interests. Furthermore, although her analysis is based largely onprinciples and parameters theory, she deliberately makes her research amenable to a variety oftheoretical frameworks.
