“It Can't be Translated Into a Conventional English Phrase”: Crafting Academic Identities Through Translingual Writing

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This qualitative multiple case study explores multilingual postgraduate students’ academic identities through writing at an EMI university in Hong Kong, with a focus on how they gain legitimacy in knowledge‑making with their multilingual repertoires. Grounded in a poststructuralist understanding of identities as fluid and negotiated, the study
