This paper discusses the notion of linguodidactic competence within the framework of foreign language teachers' professional development, underlining its dynamic and multicomponential character. In the context of modern education, linguodidactic competence integrates language proficiency with interdisciplinary knowledge, methodological skills, and cultural awareness. The research singles out the following subcompetencies: instructional design competence, cross-cultural competence, meta-communicative competence, reflective practice competence, and lifelong development competence. These sub-competencies answer the professional standards and constitute the necessary conditions to build an effective, inclusive, and adaptive practice of teaching in a turbulent educational world. The paper develops an argument on continuous development in linguodidactic competence in view of integrating digital technologies into education and making it open. By developing these competencies, the teacher will be more capable of promoting linguistic and cultural development in students for the purpose of global communication and preparing them for life in a global society.
