Introduction: The JLE editors explore multilingual perspectives in language learning, education, and society, as compared with mono- and bilingual perspectives. The notion of a separate language system turned out to be far from today’s multilingual communications. The approaches to multiple language learning have dramatically changed towards multilingualism. The editorial review aims to consider the potential of the field for the JLE. Basic Terminology and Definitions: the JLE editors dwell upon the key terms applicable to the field of multilingualism, including multilingualism on its own, plurilingualism, bilingualism, multilinguality, polylingualism, metrolingualism, heteroglossia, and linguistic repertoire. Research on Multilingualism and Beyond: in this section, the JLE readers can find a short review of the research publications on multilingualism, bilingualism, plurilingualism, and linguistic repertoire indexed in the Scopus database. Conclusion: multilingualism as a research field has a perspective for the Journal of Language and Education. Multilingualism is a many-faceted field, developing rather fast. Research on multilingualism may enrich the scope of the JLE and attract new readers.
