Agreement by Correspondence (ABC) is a theory of similarity-based surface phonological interaction, originally introduced to account for the behavior of long distance consonant assimilation patterns (Walker 2000; Hansson 2001; Rose & Walker 2004; et seq.). Recent years have seen an upsurge in work that extends ABC beyond its originally intended empirical and formal parameters. This growing body of work positions ABC as a potentially powerful framework that can account for vowel harmony, dissimilation patterns, and local segmental interactions. Investigations have reached a point where essential issues about the development of ABC need to be addressed:
- the developing architecture of surface correspondence theory;
- the extensibility of surface correspondence beyond long distance consonant assimilation;
- the relationship between ABC and alternative frameworks based on licensing or autosegmentalism; and
- the functional bases, in phonetics or psycholinguistics, underlying surface correspondence and phonological similarity.
