The research is a quantitative study that investigates the effectiveness of translanguaging on proficiency in English language by the undergraduate students who speak Saraiki language in Pakistan. The study employed a cross-sectional survey design to sample 198 participants to provide self-reported measures of translanguaging frequency using a well-validated scale and conduct a series of measures of English proficiency. The results indicated a small but statistically significant and positive relationship between both variables, translanguaging frequency and proficiency in English. Demographical factors such as gender and urban-rural residency showed no significant moderating effect, suggesting that translanguaging benefits are consistent across learner groups. The study further presents the pedagogical significance of the incorporation of translanguaging in the teaching of English to students with multilingual backgrounds, which preaches that, the teaching process should make use of all the linguistic paradigms to assist the students in learning the second language.
