This study aims to investigate refusal strategies used among Jordanian Arabic speakers and EFL learners of English in Jordan. Two Discourse Completion Tests (DCT), containing scenarios of refusal, were completed by 43 Jordanian Arabic speakers along with 37 EFL learners of English in Jordan. Data analysis reveals three main refusal categories used in the data: direct, indirect and adjuncts to refusals. Jordanian Arabic speakers used 7% direct refusals, 57% indirect refusals, and 36% adjuncts to refusals. In contrast, EFL learners used 13% direct refusals, 62% indirect refusals, and 25% adjuncts to refusals. Additionally, strategies such as insisting, insulting, praising the other, and invoking the name of God were observed. In conclusion, both groups preferred indirect refusal strategies over other types. It was also noted that EFL learners used more direct and indirect refusal strategies than Jordanian Arabic speakers but fewer adjuncts to refusals. Both groups produced similar strategies in response to the four types of situations, indicating that cultural background significantly influenced the way refusals were performed, despite the different languages used.
