Both groups equally comprised 30 female third-grade junior high school learners. statistical analyses GJT Translation tests group suggested different levels cross-linguistic influence, hence partially supporting FT/FA hypothesis, transfer hypothesis CEM for each form case. Moreover, findings indicated a possible association between group’s poor performance their incomplete L1 acquisition due intense contact majority language as L2). Consequently, teaching through learners’ background can improve preserve languages.
