Many researchers underscore the need to study bilinguals and multilinguals by unleashing different methods to fathom full range of its trajectories and complexities including their personal beliefs, policies, practices, values, norms, realities and expectations (García & Lin 2017). This study examines the multilanguage proficiency, practices, and attitudes among Bilingual Jordanians (N=22) predominantly residing in Jordan and trilingual Jordanians (N=26) living in Hungary. The participants answered to an online composite questionnaire that included a subjective overall language proficiency questionnaire, self-assessed language skills (Can-Do questionnaire), a Language Use and a language attitude Questionnaire. Results using the Spss software indicated that overall self-assessed proficiencies in each language positively correlated with the 4 language skills of that language for both participant groups. However, no statistically P significant differences in the scores of overall proficiencies between the two groups were found for Arabic (L1) and English (L2). Moreover, Language use and attitudes patterns revealed that Jordanian trilinguals exhibited greater linguistic flexibility and a more diverse multilanguage use compared to bilinguals, and they showcased a more positive outlook on multilingualism.
