Translanguaging, defined as "the deployment of a speaker's full linguistic repertoire without regard for watchful adherence to the socially and politically defined boundaries of named (and usually national and state) languages" (Otheguy et al., 2015, p. 281), has great potential to play a key role in English as a Second Language (ESL) classrooms and institutions. This article first explores the origins and historical development of the concept of translanguaging before examining more general recent developments and applications of this concept internationally and in Australia. The final section provides suggestions for how to apply some of the principles of translanguaging in the adult ESL classroom, with a particular focus on specific translanguaging practices that have been used with Direct Entry English for Academic Purposes students.
