The linguistic and cultural values of migrants, as well as their attitudes and behaviour, differ from those of the host society. All resources and values can be characterised as linguistic and cultural capital, which can provide migrants with certain advantages in their new country of settlement. A heritage language (HL) and knowledge about another culture are important components of this linguistic cultural capital. It is crucial for multi-generational families to maintain their HL and transmit the culture of their heritage to help individuals gain a better understanding of their own identity. This study aims to investigate the views, attitudes, and beliefs of second-generation migrants in Cyprus and Sweden in relation to their HL, linguistic and cultural capital, factors affecting HL use, maintenance, and development, as well as their future plans and aspirations regarding HL transmission. Narrative analysis of the semi-structured interviews revealed certain differences and similarities between the countries under investigation regarding the personal reflections of the participants and their perceptions regarding the role of family language policies, home literacy environments, child and parental agency, socio-emotional well-being, local context, and other internal and external factors influencing HL use, maintenance, and transmission. Storytelling proved to be an effective method of narrative inquiry, providing a deeper insight into the complex process of HL development and support. In addition, it offered participants an opportunity to reflect on their personality, language, and culture.
