TL;DR
- The Nederlandse Taalunie is the official Dutch-Flemish policy body for the Dutch language.
- It sets the official spelling (the Green Booklet), provides free language advice, and supports Dutch language education.
- Not a course or learning platform. Useful as a reference and authority for advanced learners, teachers, and anyone who needs definitive answers about Dutch.
What is the Taalunie?
The Nederlandse Taalunie (Dutch Language Union) is a treaty organization between the Netherlands, Belgium (Flanders), and Suriname. Founded in 1980, it is responsible for everything related to the official standards of the Dutch language.
This includes the official spelling, published as the Woordenlijst Nederlandse Taal (the Green Booklet), as well as grammar descriptions, language advice, and international promotion of Dutch.
What the Taalunie offers learners
Official spelling reference
The Woordenlijst Nederlandse Taal (woordenlijst.org) is the free, searchable online version of the official Dutch spelling list. If you ever need to know the correct spelling of a Dutch word, including hyphenation rules and plural forms, this is the definitive source.
Language advice
Through the Taaladvies service (also accessible via taaladvies.net), the Taalunie answers practical questions about Dutch. You can look up whether a word takes de or het, how to use grammar rules in edge cases, or whether a phrase is considered correct in standard Dutch.
Grammar portal
The Taalunie maintains a digital grammar of Dutch, available at e-ans.ivdnt.org. This is the online version of the Algemene Nederlandse Spraakkunst (ANS), the most complete descriptive grammar of the Dutch language. It is detailed and technical, more suited to teachers and advanced learners than beginners.
International Dutch studies
The Taalunie supports Dutch language programs at universities around the world through funding, materials, and teacher training. If you study Dutch at a university outside the Dutch-speaking area, the program may receive Taalunie support.
Who this is useful for
- Advanced learners (B2-C1) who need authoritative answers about spelling and grammar
- Dutch teachers and program coordinators
- Anyone taking official Dutch exams where correct spelling matters
- Translators, editors, and professionals working in Dutch
Who this is not for
- Beginners (A0-A2) who need structured lessons and practice
- Learners looking for interactive exercises or speaking practice
- Casual learners who want quick answers rather than detailed linguistic explanations
Limitations
The Taalunie is a policy and standards organization, not a learning platform. It sets the rules and provides references, but it does not offer courses, exercises, or feedback. The grammar portal (ANS) is linguistically detailed in a way that can be overwhelming for learners below B2.
The language advice pages are in Dutch, so you need a reasonable reading level to benefit from them.
How it fits into a learning plan
For most learners, the Taalunie is a reference tool rather than a learning resource:
- Use woordenlijst.org when you need to check the official spelling of a word
- Use taaladvies.net when you have a specific grammar or usage question
- Use the ANS grammar portal when you need deep, technical explanations
These tools complement courses and practice resources. They are most useful at B1 and above, when you can read the Dutch-language explanations and care about getting spelling and grammar exactly right.
Dutch Fluency perspective
The Taalunie is the backbone of formal Dutch. Dutch Fluency tools focus on practical speaking and listening, but knowing where to go for authoritative spelling and grammar is valuable at every level.
