In today's world, globalisation and transnational migratory flows are growing, thus leading authorities to develop and implement new icies oriented to migrants' social, cultural and linguistic inclusion (PérezIzaguirre & Cenoz, 2021). This is essential, given that the ethnocultural capital that migrants possess is often steeped in elements associated with ethnic or national identity that can result in social exclusion or ghettoisation of the migrant population (Bowman, 1997; Hage, 2016L Language can become an element of exclusion, but sometimes it can work as an element of social and cultural inclusion because it facilitates communication with local speakers, and in the context of this chapter, local Basque speakers (Roman Etxebarrieta et al., 2018). Therefore, learning the language(s) of the host society can be an important step towards inclusion. However, the complexity of the challenge increases when the host society has more than one official language, as is the case in the Basque Autonomous Community (henceforth BAC). Here, Spanish and Basque are the two co-official languages, Basque being the minoritised language.
