The Dutch Language Union (Dutch: Nederlandse Taalunie^ⓘ, NTU) is an international regulatory institution that governs issues regarding the Dutch language. It is best known for its spelling reforms which are promulgated by member states, grammar books, the Green Booklet and its support of Dutch language courses and studies worldwide. It was founded on a treaty concluded between the Netherlands and Belgium (in respect of the Flemish Community) on 9 September 1980. Suriname has been an associate member of the Taalunie since 2004.
