The learner's native language(s) have an impact on second language acquisition. All speakers ‘ languages share the processes that enable their functioning and also their knowledge repertoires, such as the phonological repertoire (Flege, Bohn & Jang, 1997; Kartushina & Frauenfelder, 2014). The functioning of languages and their common repertoires can generate cross-linguistic interferences and transfers, which either hinder or facilitate second language acquisition.
