codaposities

Codaposities are a theoretical construct used in phonology and phonotactics to model the relationship between coda segments and their permissible positions within syllable structures. The term blends coda, the consonant or consonant cluster at the end of a syllable, with posity, indicating position. A codaposity thus encodes which codas may occupy which coda slots in a given language’s syllabic template.

Formally, a codaposity is a relation between a coda type C and a positional index P within a syllable, such that the pair (C, P) is licensed if codas of type C may occur in position P. A language or dialect is described by a set of codaposities, representing all allowed C–P combinations. Constraints in a linguistic theory then determine which pairs are permitted, deleted, or ordered, enabling predictions about coda distribution across syllables and words.

Examples help illustrate the idea. In a language with only simple final codas, the codaposities might include pairs like (simple coda, final position). In a language with both final codas and restricted clusters, additional pairs such as (consonant cluster, final position) may be licensed but with specific constraints on cluster size or internal structure. Languages with limited coda licensing would show smaller codapositions sets, while those with rich coda systems would exhibit larger ones.

Applications of codaposities include cross-language typology, computational modeling of syllable structure, and the formal comparison of coda licensing rules. Limitations include the abstract nature of the construct and the need to integrate it with broader phonological theories. See also coda, syllable, phonotactics, and constraint-based phonology.
