Syllable and Segment in Latin offers new and detailed analyses of five long-standing problems in Latin historical phonology. In so doing, it clarifies the relative roles of synchronic phonological structure and phonetics in guiding sound change. While a reductionist view claims that demands of speech production and perception alone motivate and constrain phonological development in a listener-oriented model of diachronic phonology, the author shows that some developments were initiated by analogy and constrained by synchronic structure. Ranjan Sen considers examines clear and dark /l/; inverse compensatory lengthening; syllabification before stop + liquid in vowel reduction; vocalic epenthesis in stop + /l/; and consonantal assimilations. He ascertains the phonological conditions for each phenomenon, reconstructs the motivations for the changes, and develops a methodology for the appropriate use of evidence from non-current languages to evaluate theories of diachronic phonology. He evaluates the likely phonetic and phonological influences by investigating studies across languages, establishing a secure evidence base through detailed philological examination, and reconstructing the phonetics - through both general principles and pertinent experimental studies - and the relevant phonological structure of the language. The book will appeal to graduate students and researchers in historical linguistics, phonology, Classical philology, and Indo-European linguistics.
