Instituut voor de Nederlandse Taal: The Scientific Authority on Dutch

The Instituut voor de Nederlandse Taal (INT) in Leiden is the central scientific institute for the Dutch language. It builds and maintains the corpora, dictionaries, and language databases that underpin much of Dutch language education and research.

What the INT Offers

The INT at https://ivdnt.org manages essential reference works including the Algemene Nederlandse Spraakkunst (ANS), the standard grammar of Dutch, and the Corpus Hedendaags Nederlands, a massive searchable collection of modern Dutch texts. It also runs the official Dutch word list for spell-checking and contributes to taaladvies (language advice) together with Onze Taal and the Taalunie.

For advanced learners, the INT's online resources let you search real Dutch usage across millions of texts — newspapers, subtitles, legal documents, and social media. This is invaluable for understanding how words and constructions are actually used, not just how textbooks say they should be.

Good Fit For

Teachers, researchers, and advanced learners (B2+) who want to go deep into Dutch linguistics. If you are preparing academic work in Dutch, writing professionally, or simply curious about why Dutch works the way it does, the INT's resources are authoritative. The institute also publishes scholarly works on Dutch linguistics.

Limitations

The INT is not a teaching institution. You cannot take Dutch lessons there. Most resources are in Dutch and aimed at linguists, educators, and native speakers. Beginner and intermediate learners will find Onze Taal or taaladvies.net more immediately useful. The corpora require some technical skill to query effectively.
