The goal of this thesis is to explore alignment and adjacency of constituents in the framework of Optimality Theory. Under the notion of alignment, certain categories, prosodic and morphological, are required to correspond to certain other categories, prosodic or morphological. The alignment of categories is achieved through the operation of constraints which evaluate the wellformedness of outputs. The constraints on the alignment of categories and the ranking of these constraints are examined with emphasis on two Australian languages, Warlpiri and Arrernte. The aim is to provide an adequate account in the theory of Optimality of the processes of stress, reduplication and vowel harmony evident in the data. The thesis expands on the range of edges for the alignment of feet. Foot alignment is developed to account for the fact that the edges of intonational phrases, morphemes, and specific morphemes, as well as phonologically specific syllables, play an active role in determining the location of feet. An additional finding is that the location of feet can also be determined by adjacency, resolving conflict between morphological alignment, and ensuring rhythmic harmony. Requirements on adjacency are further supported to account for segmental harmony, where harmony provides evidence for the simultaneous action of segmental and prosodic processes. The analysis provides a unified account of binary and ternary rhythm recommending modifications to alignment of certain categories, thereby laying the groundwork to deal with variation. The account of variation involves relaxing certain constraints. In addition, the notion of rhythm is expanded to account for onset sensitivity to stress, with evidence of this sensitivity found in reduplication and allomorphy. The interaction of prosodic categories with each other and with morphological categories can be directly captured in OT, providing a unified and coherent account of phenomena, some of which were previously seen as exceptions and, therefore unrelated and arbitrary.
