Heritage language is the language spoken by immigrant families in the countries in which they reside. In this case, the heritage language is the Spanish that Spanish-speaking families residing in Sweden use at home.
Children of immigrants have the advantage of knowing both the language and culture of the country in which we reside as well as the Spanish language we use at home. This linguistic and cultural duality provides a more flexible way of thinking and greater job opportunities, as well as allowing cultural exchange.
The advantages become more evident when the language is cared for and transmitted thoughtfully. Being a minority language, Spanish runs the risk of being relegated to the domestic arena and as such, not being learned in depth by acquiring great fluency in reading, writing and/or language in different contexts.
