This article proposes translingual dispositions as a way to move beyond the NES/NNES dichotomy in understanding language teacher identity. Recent scholarship in TESOL and Applied Linguistics has problematized the NES/NNES binary from a poststructuralist perspective, highlighting how NES/NNES subjectivities are discursively and performatively (co-)constructed and negotiated. Despite the efforts to empower NNESs, the very binary reifies monolingual ideologies. This article argues that translingual dispositions can help move beyond the binary and complicate theorization of teachers' identities and practice. To illustrate, we report an ethnographic case study of a "NES" teacher, Daphne, and examine how Daphne's translingual dispositions shape her teaching and facilitate her students' creative negotiation of monolingual norms in a writing course. We conclude by discussing future research directions and the implications for language teacher education in fostering translingual dispositions.
