Correspondence Theory. Correspondence Theory is based on the definition of a relation and a set of constraints that by applying them to different elements of the phonological representation yield different phonological effects. Correspondence is generally defined as a “special relation between two structures.” The authors say: Here I will assume that the structural elements in question are just (tokens of) segments but it is a straightforward matter to generalize the approach to higher order units of prosodic structure such as moras, syllables, feet, heads of feet, as well as tones and even distinctive features or feature nodes [emphasis added], in support of theories of quantitative transfer, compensatory lengthening, and the effects of floating features (XxXxxxxx & Prince 1995:14). Much work has been done in Correspondence Theory, such as in its application to other domains such as transderivational identity (Benua 1997), feature nodes (Akinlabi 19961), and reduplication (Inkelas 2008), as well as on the analysis of some specific formal properties of correspondence constraints and relations (Xxxxxx 1997, Xxxxx & Xxxxxx 2002, Xxxxx et al. 2017). In all cases, correspondence relate elements of the same “nature,” but with some different “properties”2 (e.g., input–output or base–reduplicant segments, tone–TBUs, etc.). For this reason, a crucial axiom of correspondence relations is heterogeneity. In this 1 The suggested relations refer to correspondence between feature nodes and root nodes as opposed to φ- Correspondence, which instead acts on feature node heads and dependents.
