This paper documents English teachers' and advanced English students' perspectives on the use of Spanish in the English classroom in Puerto Rico. Using qualitative data collection methods such as interviews and focus group data, the researchers document the ways that many English teachers on the island justify their use of Spanish in the English classroom as they work to make their teaching more comprehensible. Nevertheless, the advanced students from both public and private schools who participated in this study offer a note of caution regarding the use of too much Spanish in the English classroom. Ultimately, findings suggest that many English teachers consciously or unconsciously adopt a translanguaging approach that needs to be assessed critically depending on the language proficiency and confidence of the students in their classrooms.
