The present volume, edited by Patricia Salazar-Campillo and Victòria Codina-Espurz, is a timely contribution to the field of interlanguage pragmatics. The nine chapters presented here expand the scope of research to date by including different contexts (i.e., formal instruction, stay-abroad, and online) and age groups which have received less attention (for example, young learners and adolescents). Whereas the speech act of requesting is the one that has been most explored in the field of interlanguage pragmatics, as attested by several chapters in the present volume, disagreements and directives are also tackled. This book embraces research addressing both elicited and naturally-occurring data in studies which deal with pragmatic use, development, and awareness.
