Ninety undergraduate students enrolled in a public university in the UAE took part in the study. Data collection involved a background questionnaire, a vocabulary size task, and a vocabulary depth task. Using the background questionnaire, the participants were separated into the early, middle, and late learners - those exposed to EMI in elementary, secondary, and tertiary levels, respectively. The results revealed a significant multivariate main effect for the AO to vocabulary knowledge. The post hoc analysis confirmed a significant effect for vocabulary size only; no such effects were observed for vocabulary depth. Theocratical, methodological, and pedagogical implications are discussed.
