This competence defines the ability to use different languages appropriately and effectively for communication. It broadly shares the main skill dimensions of communication of literacy: it is based on the ability to understand, express, and interpret concepts, thoughts, feelings, facts and opinions in both oral and written form (listening, speaking, reading and writing) in an appropriate range of societal and cultural contexts according to one’s wants or needs. As appropriate, it can include maintaining and further developing mother tongue competences. A learner’s level of proficiency will vary between the four dimensions and between the different languages.
