This paper sets out to develop a finer-grained understanding of the 'plurilingual social actor' within an Anglophone higher educational setting. Drawing on data collected as part of The Multilingual University project, I examine how a group of plurilingual postgraduate students taking modules in applied linguistics at a university in London viewed their linguistic repertoires as a resource for the taught curriculum and what their experiences can tell us about the plurilingual social actor. The study opened an institutional space for making linguistic diversity visible and for considering how it was a resource for the curriculum. The findings indicate that multilingual resources play an important role in supporting learning at postgraduate level and reveal ways in which familiarity with English medium education shapes how postgraduate students mobilise their multilingual resources in relation to the taught curriculum. Importantly, the study shows how the plurilingual social actor offers a dynamic, powerful and affirmative identity position that is well aligned with the teaching and learning agenda in higher education. It is my contention that a better understanding of this alignment will allow us to raise awareness of language-as-resource and advance plurilingual pedagogies in the sector.
