structurephonology

Structurephonology is an interdisciplinary framework in linguistics that studies how linguistic structure interacts with phonology. It treats phonological form as determined not only by segmental inventories and phonotactics but also by higher-level structural representations such as syntactic trees, prosodic hierarchies, and morphosyntactic boundaries. The central aim is to model how structure guides the realization of phonological contrasts, segmental sequences, rhythm, and prosody.

In structurephonology, phonological phenomena are analyzed as mappings from structural representations to phonological form. This includes the placement of stress and tone, the tuning of syllable structure, phonotactic patterns, and discourse-driven prosody, all constrained by the underlying syntax and morphology. The approach often employs interface constraints between levels, alignment and containment relations, and typological comparisons to understand universals and variation.

Common topics include how syntactic boundaries influence intonational phrasing; how word formation and affixal morphology affect phonological forms; and how long-distance dependencies, focus, and information structure interact with prosodic patterns. The methodology combines formal modeling, cross-linguistic typology, corpus studies, and experimental work to test predictions.

Structurephonology sits at the intersection of phonology, syntax-phonology interface research, and morphophonology, offering tools for explaining morphophonological alternations and prosodic organization that correlate with structural units. While not universally adopted as a separate field, it functions as a distinct perspective within theoretical and experimental linguistics to clarify the role of structure in phonology.
