interlinguistic

Interlinguistics, or interlinguistic studies, is the interdisciplinary field that examines language relations and cross-linguistic communication. It analyzes how languages influence one another, how people translate and interpret across linguistic boundaries, and how policies, technologies, and educational practices shape multilingual interaction.

Core topics include language contact phenomena (borrowings, calques, code-switching), mutual intelligibility and translation equivalence, interpretation, localization, terminology management, and the design and evaluation of constructed or auxiliary languages intended to facilitate international communication. The field also considers language planning and policy, intercultural communication, and the social, cognitive, and technological factors that affect interlingual understanding.

Interlinguistics draws on linguistics, translation studies, sociolinguistics, typology, and computer science to study both natural languages and artificial languages. It addresses how multilingual societies function, how information is conveyed across language boundaries, and how tools and practices can be improved to support accurate communication.

Methods commonly employed include descriptive analysis of multilingual corpora, studies on comprehension and translation performance, and computational modeling for machine translation and localization. The overarching aim is to enhance cross-language understanding, improve translation quality, and inform language policy and planning in multilingual contexts. The term interlinguistic is used to describe concepts, practices, and research that relate to the broader aims of interlinguistics and cross-linguistic communication.
