The Meertens Institute studies and documents language and culture in the Netherlands as well as Dutch language and culture throughout the world. We focus on the phenomena that shape everyday life in society. In the current political climate, language and culture are considered to be hallmark contributors to collective identity. The Meertens Institute, which researches the “Dutch case” from a comparative and international perspective, would also like to contribute to the social debate by clarifying and providing nuance to the role of language and culture in social processes. This research plan summarizes the research ambitions of the Meertens Institute for the years 2018-2023.
