This book is the result of an investigation carried out with two Uruguayan students on a degree course in Portuguese/Spanish Languages. Based on the assumption that the construction of identity is a process that involves language, this research was carried out in order to find out how the process of constructing the teaching identity of these students takes place. According to De Nardi (2005, p.6), when "we talk about identity and subject, we are therefore talking about language and subjects, since we are entering the space of the symbolic, of a symbolic mediation that allows the production-understanding of a language". Language is therefore conceived as a symbolic dimension that allows the subject to identify itself. In other words, in this work it will be possible to visualize how each of the informants sees and feels in both languages and what these languages mean to each of them, thus elucidating the processes these students go through to assume and construct their teaching identity.
