conditioning : phonological and morphological

Morphologically conditioned phonology is the phenomenon in which a particular phonological pattern is imposed on a proper subset of morphological constructions (affixation, reduplication, compounding) and thus is not fully general in the word‑internal phonological patterning of the language. This chapter focuses on the types of morphological information that can condition phonological patterns and the types of phonological patterns that can be conditioned by morphology. The chapter addresses conditioning by lexical classes, part of speech, and individual morphological constructions. Also covered are several of the most influential theories of morphologically conditioned phonology, which aim to capture language‑specific as well as cross‑linguistic generalizations about the phenomenon. The range of variation that a given language can exhibit in its phonological patterns is discussed.
