This chapter focuses on the topic of language teacher identity within a specific field of language learning and teaching. TILLT is the acronym of this field and it stands for Translation and Interpreting-oriented Language Learning and Teaching. In order to give an overview of this particular higher education context the chapter starts with a discussion of TILLT, followed by recent developments and major contributions. The main focus of this chapter, however, is to offer a conceptualization of TILLT teacher identity, while, at the same time, acknowledging the students' identity issues as future translators and interpreters. The chapter concludes with some recommendations for future research directions in this promising emerging academic field.
