Interlinguistics, also known as cosmoglottics, is the subfield of linguistics that studies planned languages with practical and theoretical perspectives. Formalised by Otto Jespersen in 1931 as the science of interlanguages, in more recent times, the field has been more focused with language planning, the collection of strategies to deliberately influence the structure and function of a living language. In this framework, interlanguages become a subset of planned languages, i.e. extreme cases of language planning. Interlinguistics first appeared as a branch of studies devoted to the establishment of norms for auxiliary languages, but over its century-long history it has been understood by different authors more and more broadly as an interdisciplinary branch of science which includes various aspects of communication, language planning and standardization, multilingualism and globalisation, language policy, translation, sociolinguistics, intercultural communication, the history of language creation and literature written in constructed languages (international auxiliary languages (auxlangs) as well as constructed languages : conlangs), fictional artistic languages (artlangs), lingua francas, pidgins, creoles and constructed languages in the internet and other topics were added.
Etymology and history
The hybrid term was first coined in French (as Interlinguistique) by the Belgian Esperantist Jules Meysmans. The main historical periods of interlinguistics are:
first, the pioneer era (1879–1911), when its basis was put forth; secondly, the foundational era (1911–1951), when the interlinguistics wars took place to decide the most appropriate form of an auxiliary language; thirdly, the school era (1951–1990), when independent Interlinguistics schools formed in different countries, mainly Germany, Hungary, Italy, the Netherlands, and Poland, each with particular attention to Esperanto; lastly, the current era of language policy (1990–today), during which interlinguistics is more tightly integrated with other disciplines, mainly linguistics and various social and political sciences, particularly via the topics of globalism, linguistic justice, management of multilingualism, and new forms of mobility. At the Institute of Linguistics of Adam Mickiewicz University (Poznań) there is the extramural Interlinguistic studies program. "Over the course of three years these studies provide the students with a basic knowledge of general linguistics, interlinguistics, international and intercultural communication with a focus on the linguistics, culture and movement of the internationally dispersed and naturally functioning planned language Esperanto." As of 2017, every third year the Interlinguistic Studies program was also organizing an international interlinguistic symposium. The University of Amsterdam also has a chair of interlinguistics and Esperanto.
Field of studies The field of interlinguistics is concerned with international planned languages [also called 'constructed languages', 'auxiliary languages', or 'artificial languages'] as Esperanto, and with the relationship between planned languages and language planning. Increasingly, undergraduate courses in planned languages are expanding to embrace not only the history of languages planned for international use, but also the field of imaginary and fictional languages. Interlinguistics is also concerned with investigating how ethnic and international planned languages work as lingua franca and with the possibilities of optimizing interlinguistic communication. The term Interlinguistics can be interpreted in at least two ways:
