Reseña del libro "Lenition and Fortition (en Inglés)"
There are books on tone, coronals, the internal structure of segments, vowel harmony, and a couple of other topics in phonology. This book aims to fill the gap for Lenition and Fortition, which is one of the first phenomena that was addressed by phonologists in the 19th century, and ever since contributed to phonological thinking. It is certainly one of the core phenomena that is found in the phonology of natural language: together with assimilations, the other important family of phenomena, Lenition and Fortition constitute the heart of what phonology can do to sound.The book aims to provide an overall treatment of the question in its many aspects: historical, typological, synchronic, diachronic, empirical and theoretical. Various current approaches to phonology are represented.The book is structured into three parts: 1) properties and behaviour of Lenition/Fortition, 2) lenition patterns in particular languages and language families, 3) how Lenition/Fortition work. Part 1 describes the properties of lenition and fortition: what counts as such? What kind of behaviour is observed? Which factors bear on it (positional, stress-related)? Which role has it played in phonology since (and even before) the 19th century? The everything-you-always-wanted-to-know-about-lenition-and-fortition philosophy that guides the conception of the book supposes a descriptive, generalisation-oriented style of writing that relies on a kind of phonological lingua franca, rather than on theory-laden vocabulary. Also, no prior knowledge other than about general phonological categories should be required when reading through Part 1. The goal is to provide a broad picture of what lenition is, how it behaves, which factors it is conditioned by and what generalisations it obeys. This record may then be used as a yardstick for competing theories.Part 2 presents a number of case stud
