What are the levels of the prosodic hierarchy?

Commonly cited levels, from smallest to largest, are the syllable, the foot, the prosodic word, the phonological phrase, the intonational phrase, and the utterance, each serving as a domain for certain phonological processes.

Why is prosodic structure distinct from syntax?

Prosodic phrasing often does not match syntactic structure exactly; for instance, the way a sentence is grouped for phonological purposes can differ from its syntactic bracketing, which motivates an independent prosodic hierarchy.

The Prosodic Hierarchy

The prosodic hierarchy is a layered set of phonological constituents—from the syllable up to the utterance—that organizes speech and conditions phonological processes.

Definition

The hierarchically organized set of prosodic constituents that structures the phonological representation of utterances and defines domains for phonological processes.

Scope

This topic covers the theory that speech is organized into a hierarchy of prosodic units: the syllable, foot, prosodic word, phonological phrase, intonational phrase, and utterance. It treats the principles governing this layering, such as the strict layer hypothesis, and the role prosodic constituents play as domains for phonological rules and for phrasing. It also covers the relation between prosodic structure and syntactic structure, which influence but do not strictly determine one another. The treatment is descriptive and analytic.

Core questions

What are the levels of the prosodic hierarchy?
What principles govern how prosodic constituents are layered?
How do prosodic constituents serve as domains for phonological rules?
How does prosodic structure relate to syntactic structure?

Key theories

The prosodic hierarchy and the strict layer hypothesis: Nespor and Vogel's and Selkirk's proposal that phonological structure consists of nested prosodic constituents, ideally with each level immediately dominated by the next higher one, defining the domains in which phonological rules apply.

History

Prosodic phonology developed in the early 1980s through the work of Selkirk and of Nespor and Vogel, who argued that phonological rules apply within constituents that form a hierarchy distinct from syntax. The framework became central to the study of the phonology-syntax interface.

Debates

Strictness of layering and mapping from syntax: Scholars debate whether prosodic structure must obey strict layering and how prosodic constituents are derived from syntactic structure, since observed phrasing sometimes violates strict layering or diverges from syntactic bracketing.
