This article explores university English as a Second Language (ESL) instructors' attitudes toward translanguaging in the classroom and possible reasons for instructors' resistance in moving translanguaging ideology into English language teaching pedagogy. Many researchers have forwarded translanguaging as a theoretical and pedagogical approach to language education because of its potential cognitive, social, and affective benefits. A translanguaging pedagogy calls for instructors to affirm the dynamic and diverse language practices that multilingual students utilize as part of their unitary language repertoire. However, because English-only pedagogies, policies, and practices still permeate the ESL classroom, it is critical to understand how ESL instructors' language ideologies and orientations play a role in shaping their pedagogical practices and classroom language policies. Using Ruíz's orientations in language planning and translanguaging theory, this study examined the language orientations of five ESL instructors at a major Canadian university based on qualitative data gathered through semi-structured interviews. The findings provide insights into instructors' attitudes toward translanguaging, the relationship between instructors' language learning experiences and their classroom language policy, and institutional opportunities and constraints.
