This monograph provides a unified account of French Prosodic Morphology (PM) (comprising abbreviations, acronyms, language games, hypocoristics, echo-words, and reduplications). It is argued that the output of each of these processes conforms to a well-formedness template: a Prosodic Word consisting of no more than two metrical feet. Crucially, this template is defined with reference to the iambic foot and relies on the moraic status of French coda consonants. Evidence from stress and vowel quantity/quality indicate that French coda consonants are invariably moraic which leads to a unified analysis of final consonant deletion, liaison, and vowel nasalization. The mora is also central in defining the Prosodic Word template, crucially operating as a well-formedness constraint and not a mapping target. Finally, French PM is shown to be lexical, accounting for its interaction with morphological processes and the unpredictability of the precise phonemic content of a given PM-form. In addition, this book includes extensive appendices of abbreviations, reduplication, hypocoristics, and echo-words.
