This chapter presents a collaboration between a sociologist and a translation scholar. Reflecting on the transdisciplinarity of translation and interpreting studies, the authors highlight differences, similarities and connections between this ‘interdiscipline’ and sociology. It starts with a record of the relationships between sociology and translation studies, moving to a reflection on the relationship between research and practice, then it focuses on social constructivism as a potential bridge. In particular, it analyses the contributions of actor-network theory and social systems theory. The chapter culminates with the question of the combinability of social theories.
