While it is known that heritage speakers diverge from the homeland baseline, there is still no consensus on the mechanisms triggering this divergence. We investigate the impact of two potential factors shaping adult heritage language (HL) grammars: (1) cross-linguistic influence (CLI), originally proposed for second language acquisition (SLA), and…

In the context of German linguistic policies, Heritage Language (HL) education ranges from formal and informal to non-formal offers. Families with migratory backgrounds seeking acquisition and maintenance of the HL frequently resort to educational or maintenance opportunities that are not institutionalized. In the region of Bavaria (Germany), the…

Heritage languages (HLs) are acquired in contexts of unbalanced input, or situations in which children receive primary exposure to the family/HL and experience an abrupt shift after the child begins formal schooling. As a consequence, HL speakers normally become more dominant in the environmental language, while the development of the HL is…

This study addresses the question of how the main factors related to input--including the environment in which children are exposed to both languages, the relative timing of the onset of the exposure to them and the amount of input--affect bilingual language acquisition at primary-school age. We examined the data of 42 German Polish bilinguals who…

This longitudinal study examined the development of narrative micro- and macrostructure in Japanese-English bilingual returnee children. Returnees are children of immigrant families who move to a foreign country, spending a significant portion of their formative developmental years in the foreign majority language context before returning to their…

Immersion programs have long been considered the gold standard for school-based language revitalization, but surprisingly little attention has been paid to the quantity and quality of the input that they provide to young language learners. Drawing on new data from three such programs (Kaqchikel, Western Subanon, and Maori), each with its own…

This study explores the language use of Southeast Asian marriage-migrant mothers in South Korea with their mixed-heritage children, and the challenges related to heritage language (HL) transmission. Drawing on interviews with nine women, the study finds that they encountered multiple obstacles to teaching the HL to their children. Their Korean…

Drawing on theories of family language policy and literacy environment, this inquiry explores and describes how family language policy is managed through literacy resources and literacy related activities in transnational families in the UK. A total of 66 families, each with at least one child between the age of 2 and 8, participated in this…

Heritage grammars, linguistic varieties emerging in the context of intergenerational language loss, are known to diverge from the corresponding full-fledged baseline varieties in principled and systematic ways, as typically illustrated by errors made by heritage speakers in production. This dissertation examines "covert" restructuring of aspect in…
