If students studying in European Schools are not able first to develop their national identity through the use of their mother tongue and culture, I believe that they will not have a strong basis to build their European identity.
Si los estudiantes de las Escuelas Europeas no son capaces, primero, de desarrollar su identidad nacional a través del uso de su lengua materna y cultura, pienso que no tendrán una buena base para crear su identidad europea.
