Phonology¶

8 domain-specific abstractions whose origin domain is Phonology.

Consonant cluster — A sequence of adjacent consonantal segments without an intervening vowel within a syllable, word, or declared phonological domain.
Distinctive feature — A minimal phonological property whose contrastive value distinguishes segments and defines natural classes, represented in feature systems as binary, privative, or geometry-organized specifications.
Paraphonemic sound — A speech-like sound conventionally used for expressive, mimetic or interactional purposes but excluded from a language's ordinary lexical phoneme inventory.
Phonological rule — A formal mapping from underlying sound representation to a context-conditioned surface realization.
Pitch-accent language — A contested prosodic type in which lexically contrastive pitch prominence is restricted to one position or pattern per word, intermediate in some analyses between stress and unrestricted tone systems.
Sonority sequencing principle — A phonotactic generalization that syllable sonority tends to rise toward the nucleus and fall toward the edges, subject to language-specific exceptions.
Ts–ch merger — A phonological merger in which voiceless alveolar and postalveolar affricates lose their contrast in a language or dialect.
Vowel reduction in Russian — The systematic change and merger of unstressed Russian vowel qualities according to stress position, consonantal context, dialect and speech style.
