Contemporary Advances in Theoretical and Applied Spanish Linguistic Variationampampnbspby Juan J. ColominaAlmiana reframes the understanding of language variation and change as an intimate interplay between both linguistic features and social factors always occurring in unison in the same historical process.ampampnbspIts ten chapters divided into four parts provide both a synchronic and a diachronic view of Hispanic sociolinguistics focusing not only on the historical development of Spanish as a Romance language but also analyzing certain idiosyncratic elements of nonstandard Spanish varieties across multiple regions nations and diasporas. In addition the volume offers an enchronic perspective of this phenomenon by analyzing how certain sustained cultural practices may drive concrete linguistic developments. ampampnbsp This volume makes three major contributions to Hispanic sociolinguistics. First it covers variation in less commonly studied varieties which are new areas of interest in a broader world where certain minorities and their languages are crucial. Second it offers recent and innovative approaches to variation coming from formal theories in order to spark a debate about methodology that is more comprehensive of the diverse approaches to variation currently practiced in the field. Finally it includes chapters that combine quantitative and qualitative analysis of different linguistic variables. ampampnbsp
