This study investigates the impact of using Duolingo to enhance vocabulary acquisition among eighth-grade students at Taman Pendidikan Islam Junior High School in Medan. Ineffective teaching methods are the root cause of the issue of inadequate vocabulary mastering. The study employed a quantitative approach with a pre-experimental design, encompassing all pupils in the eighth grade. Both a pretest and a posttest were administered before and after a two-week period of using Duolingo in order to assess the level of improvement. The results demonstrated a substantial enhancement in students' vocabulary acquisition, as seen by the higher mean score (83.84) on the posttest compared to the pretest (52.80). The statistical study using a paired sample t-test revealed a significance value of 0.000, demonstrating a significant improvement in vocabulary learning as a result of using Duolingo. Ultimately, Duolingo proves to be efficacious in enhancing students' lexical acquisition, offering an enjoyable and engaging educational encounter, and fortifying students' retention through efficient repetition and utilisation of words in many contexts. Based on these findings, it is advised that students use the Duolingo application to increase their vocabulary.
