The official or standard form of Dutch is known as Algemeen Beschaafd Nederlands (ABN), 'general civilized Dutch'. It is taught in schools and used by authorities in the Netherlands, Flanders (Belgium), Suriname and the Netherlands Antilles. An association known as the Taalunie (Language Union) set up by governments of the Netherlands and Flanders regulates the orthography and spelling of ABN. Alternative names for ABN are Algemeen Nederlands (AN), general Dutch, and Standaardnederlands, standard Dutch.

The Dutch dialects spoken in Belgium are collectively know as Flemish (Vlaams). They differ to some extent from the Dutch spoken in the Netherlands in terms of intonation and pronunciation, and there are minor differences in vocabulary, including loanwords from French and English not found in Standard Dutch.
