The present volume On Words and Sounds is a collection of selected papers from PLM 2009. The Poznan Linguistic Meeting (PLM) is an annual international general linguistics conference. The book consists of fifteen articles, each of which can be read separately or in relation to others. The book will definitely appeal to the academic readership interested in linguistic disciplines such as: phonetics and phonology, morphology, syntax, sociolinguistics, pragmatics and clinical linguistics. Collectively, the contributions investigate the interrelationships among those disciplines as well as between language and music. The central aim for the scholars was to explore the PLM 2009 leitmotif Variants, Variability, Variation and show that the complete study of language involves diversified frameworks often rooted in interdisciplinary approaches.
