This volume includes a selection of contributions (fifty papers and six plenary lectures) presented during the Eleventh International Conference on Late and Vulgar Latin, held at the University of Oviedo (Asturias, Spain) on 1-5 September 2014. These studies cover a wide range of topics: phonetics, morphology, syntax, vocabulary, semantics, onomastics, pragmatics, sociolinguistics, and many others. The cast of authors is varied as well, regarding not only their nationality or age, but also their specialization: veteran and young experts in Latin, Romance languages or History from more than a dozen countries of Europe and America offer here an attractive overview of current research on late and vulgar Latin.
