Dominant Language Constellation approach, as a new research field, calls for new conceptual tools, for reviewing established theoretical stances, and for methodological innovations. In this introductory chapter, we relate Dominant Language Constellations to the concepts of Language(s) Awareness and (multilingual) Identity, and we explain how it contributes to the visual and material turn in applied language studies. We claim that the Dominant Language Constellation framework brings new lenses to analyse language(s) awareness and identity, particularly in the fields of foreign language learning and teaching.
