The present issue consists of articles in various areas of SLA and also research in multilingualism. The thematic spread starts with the text related to the sociolinguistic variable of age: "The Age Factor in the Foreign Language Class: What Do Learners Think?" by Simone E. Pfenninger and David Singleton, followed by a study of non-native speaker e-mail communication (Jan Pikhart) and another paper addressing a sociolinguistic variable: "Do Girls Have All the Fun? Anxiety and Enjoyment in the Foreign Language Classroom by Jean-Marc Dewaele et al. The second group of articles begins with the text addressing the issues of multilingualism: "Multilingual Processing Phenomena in Learners of Portuguese as a Third or Additional Language" by Teresa M. Włosowicz, followed by a study of code-switching practices among immigrants in the UK by Katarzyna Ożańska-Ponikwia. The final paper by Beata Grymska represents a more theoretically-oriented perspective delving into the theoretical conceptualizations of language aptitude.
