Language and language tools

The Nederlandse Taalunie works in the interest of everyone using or learning Dutch. It ensures that the Dutch language is well described and that the grammar rules are easily accessible. This is a prerequisite for good education and linguistic advice.

Language advice

The Taalunie ensures that the grammar rules are easily accessible for the language user and provides reliable Taaladvies (linguistic advice) via its website Taalunieversum. A commission of language experts meets regularly to formulate answers to frequently occurring questions.


The Taalunie is responsible for the official Dutch spelling. This is laid down in the Woordenlijst Nederlandse Taal (Dutch Language Wordlist). Every ten years the Woordenlijst is updated with new words.


The Taalunie looks after Dutch words past and present. The Instituut voor de Nederlandse Lexicologie (Institute for Dutch Lexicology) in Leiden is the major partner in this. Its website contains all kinds of information on Dutch words, including pre-mediaeval words. The most important work of reference is the Woordenboek der Nederlandse Taal (The Dictionary of the Dutch Language), the largest dictionary in the world;it contains over 430,000 entries for Dutch words from 1500 to 1921.


The official grammar of the Dutch language is set out in the Algemene Nederlandse Spraakkunst (ANS) (General Dutch Grammar), a handbook produced with the support of the Taalunie. The electronic version is available free of charge at
