Phonology

Phonology studies the sound systems of languages — how speech sounds are organized, patterned, and function to distinguish meaning.

Scope

It covers phonemes and features, phonological rules and processes, syllable and prosodic structure, and theoretical frameworks from structuralist to generative and autosegmental phonology.

Core questions

• How are sounds organized into a system?
• What distinguishes one sound from another functionally?
• What rules govern sound patterns and alternations?
• How is phonological structure best represented?

Key concepts

• Phoneme
• Distinctive features
• Phonological rules
• Syllable structure
• Tone and prosody
• Autosegmental tiers

Key theories

The phoneme and oppositions

Trubetzkoy systematized the phoneme and the analysis of distinctive oppositions.

Generative phonology

Chomsky and Halle recast phonology as a rule system operating on distinctive features.

Autosegmental phonology

Goldsmith introduced multi-tiered representations to handle tone and other suprasegmentals.

History

Phonology developed from the Prague School's phoneme theory (Trubetzkoy) through generative phonology (Chomsky & Halle) and autosegmental and, later, Optimality-Theoretic frameworks.

Debates

Rules versus constraints

Whether phonological patterns are best captured by ordered rules or by ranked constraints (Optimality Theory).

Frequently asked questions

What is a phoneme?

The smallest unit of sound that can distinguish meaning in a language (e.g., /p/ vs /b/ in 'pat' vs 'bat').
