From its founding, the Centre for Research and Documentation on World Language Problems (CED) has worked for the advancement of scholarly research on Esperanto and its diverse contributions to international communication and global connections among people. To that end, CED is responsible for compiling and elaborating factual documentation and analysis of Esperanto and other constructed languages, as well as of the broader cultural and political context in which such languages develop and function. On this basis, we support the dissemination and development of scholarship on interlinguistics, language planning and language policy, including its application to thework of international organizations, public institutions, and civil society.

Epistemic communities

“Esperanto kaj Internaciismo, 1880-1920”, a collaborative project in the School of History at the University of St Andrews. Prof. Struck. and his students research about experts in the Esperanto movement as 'epistemic communities', e.g. doctors, architects, and urban planners.

Linguistic Justice

Language policy affects the level of inequality between languages. Large inequalities are often seen as a source of conflict. Evidence of linguistic justice would make it possible to define such distributional effects across time and space, and to control their development, thus leading to activities to control them.

CED offers

mentorships and hosts associated researchers

CED builds networks and supports the work of early career researchers, aiming to strengthen collaboration among those working on language policies and interlinguistics.
