In many English classes, students are expected to use English only, even when they already know and use other languages. This study examines what happens when learners draw on their full linguistic repertoires (often called translanguaging) while learning English, and how this relates to their motivation. We surveyed 386 multilingual university students in an intensive English program in Türkiye and analyzed how frequently they used multilingual strategies (e.g., multilingual note-taking, planning, researching, and peer collaboration) and how motivated they felt about learning English. Overall, students who reported more translanguaging practices also reported more positive English learning experiences and stronger visions of themselves as future English users (e.g., imagining using English confidently in social/professional life). In contrast, translanguaging was not meaningfully related to motivation driven by external pressures and expectations (e.g., learning English to meet others’ demands).
