Stress and Metrical Structure

Stress is the relative prominence of syllables, analyzed in metrical phonology as a property of hierarchical rhythmic structure rather than of individual segments.

Definition

The relative prominence of syllables and its representation in hierarchical metrical structure built from feet and higher prosodic constituents.

Scope

This topic covers the analysis of stress and rhythm. It treats the metrical representation of prominence through feet built over syllables, the role of syllable weight in quantity-sensitive stress, and the parameters by which languages differ in foot type and the direction of foot construction. It also covers the relation of stress to rhythm and the alternation of strong and weak syllables. The treatment is descriptive and analytic, surveying the framework and typological variation rather than prescribing pronunciation.

Core questions

• What makes a syllable stressed relative to its neighbors?
• How does metrical structure represent stress?
• What role does syllable weight play in stress assignment?
• How do languages vary in their stress patterns?

Key theories

Metrical grid and tree representation

Liberman and Prince's proposal that linguistic rhythm and stress are represented by relational structures—metrical trees and grids—encoding relative prominence rather than absolute stress features.

History

Metrical phonology began with Liberman and Prince's 1977 analysis of stress and rhythm, replacing segmental stress features with relational structure. Hayes's parametric theory of foot inventories and his 1995 synthesis systematized cross-linguistic stress typology.

Debates

Foot inventory and quantity sensitivity

Theorists debate which foot types are universally available and how syllable weight should be defined, since different parameter settings predict different attested and unattested stress systems.

Frequently asked questions

What is a metrical foot?

A metrical foot is a rhythmic grouping of syllables, typically containing one strong (stressed) syllable and one or more weak syllables, used to represent stress patterns hierarchically.

What is quantity-sensitive stress?

Quantity-sensitive stress is stress assignment that depends on syllable weight, so that heavy syllables (for example those with long vowels or codas) attract stress more readily than light syllables.
