Morphophonological asymmetries in affixation concern systematic correlations between morphological properties of affixes (e.g. combination with bound versus free stems, position relative to stem (suffixes versus prefixes)) and their phonological properties (e.g. stress behaviour). The arguably most insightful approach to capturing relevant asymmetries invokes a notion of affix coherence, first introduced by Dixon in connection with his work on Yidiɲ, a nearly extinct language spoken in Northern Australia. This notion is based on a categorical division of affixes into ones that integrate into the phonological word of the stem and ones that do not. The integration of affixes is envisioned as being fully determined by phonological and morphological structure in a given language and verifiable by diagnostics relevant to phonological word domains (primarily the syllable and the foot structure). The assumption of two types of prosodic domains characterized by integrated versus non-integrated affixes is manifest in consistent asymmetries that pertain to morphophonological, phonological, and phonetic rules. This consistency constitutes compelling evidence for the structure-based analysis of the impact of various affixes on derived words, as opposed to alternative approaches to capturing these effects by associating affixes with diacritics (morpheme versus word boundary, class 1 versus class 2, stratum 1 versus stratum 2). The present entry aims to demonstrate, mostly on the basis of data from Germanic languages, the breadth of the empirical evidence in support of a fundamental role of affix coherence. Moreover, it aims to draw attention to the various implications of affix coherence for modeling relevant generalizations, in particular the necessary reference to a level of phonological representation characterized by a specific degree of abstractness (‘phonemic’).
Notions such as “corpus-driven” versus “theory-driven” bring into focus the specific role of corpora in linguistic research. As for phonology with its intrinsic focus on abstract categorical representation, there is a question of how a strictly corpus-driven approach can yield insight into relevant structures. Here we argue for a more theory-driven approach to phonology based on the concept of a phonological grammar in terms of interacting constraints. Empirical validation of such grammars comes from the potential convergence of the evidence from various sources including typological data, neutralization patterns, and in particular patterns observed in the creative use of language such as acronym formation, loanword adaptation, poetry, and speech errors. Further empirical validation concerns specific predictions regarding phonetic differences among opposition members, paradigm uniformity effects, and phonetic implementation in given segmental and prosodic contexts. Corpora in the narrowest sense (i.e. “raw” data consisting of spontaneous speech produced in natural settings) are useful for testing these predictions, but even here, special purpose-built corpora are often necessary.
