This study aims to instil a sense of awareness particularly to English practitioners to realize the importance of vocabulary teaching in assisting learners to acquire vocabulary. Their awareness is important as they are the ones who deal with learners and the curriculum. Hence, besides knowing the strategies to teach literacy skills, they should also know and use the strategies in teaching vocabulary. One of the strategies is using languaging which in a way encourages learners to work cooperatively. The main objective of this study is to find out the ESL learners’ perceptions about languaging as a process of acquiring vocabulary; to find out the ESL practitioners’ perceptions about using languaging in the classroom; the specific research questions explored in this study are: What are the ESL learners’ perceptions about acquiring vocabulary through languaging? What are the ESL practitioners’ perceptions about using languaging in the classroom?
