|Abstract:||Alignment and Adjacency in Optimality Theory:
Evidence from Warlpiri and Arrernte
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.
