Dutch orthography

Dutch orthography uses the Latin alphabet. The spelling system is issued by government decree and is compulsory for all government documentation and educational establishments.

Legal basis

In the Netherlands, the official spelling is regulated by the Spelling Act of 15 September 2005. This came into force on 22 February 2006, replacing the Act on the Spelling of the Dutch Language of 14 February 1947.
The Spelling Act gives the Committee of Ministers of the Dutch Language Union the authority to determine the spelling of Dutch by ministerial decision. In addition, the law requires that this spelling be followed "at the governmental bodies, at educational institutions funded from the public purse, as well as at the exams for which legal requirements have been established". In other cases, it is recommended, but it is not mandatory to follow the official spelling.
The Decree on the Spelling Regulations of 2005–2006 contains the annexed spelling rules decided by the Committee of Ministers on 25 April 2005. This decree entered into force on 1 August 2006, replacing the Spelling Decree of 19 June 1996.
In Flanders, the same spelling rules are currently applied by the Decree of the Flemish Government Establishing the Rules of the Official Spelling and Grammar of the Dutch language of 30 June 2006.

Alphabet

The modern Dutch alphabet, used for the Dutch language, consists of the 26 letters of the ISO basic Latin alphabet. Depending on how is used, six letters are vowels and 20 letters are consonants. In some aspects, the digraph IJ | behaves as a single letter. is the most frequently used letter in the Dutch alphabet, as it is in English. The least frequently used letters are and, similar to English.

Sound to spelling correspondences

Dutch uses the following letters and letter combinations. For simplicity, dialectal variation and subphonemic distinctions are not always indicated. See Dutch phonology for more information.
The following list shows letters and combinations, along with their pronunciations, found in modern native or nativised vocabulary:
The following additional letters and pronunciations appear in non-native vocabulary or words using older, obsolete spellings :

Loanwords

often keep their original spellings: cadeau 'gift' . are sometimes adapted to, but are usually retained. Greek letters become, not, but usually becomes . -- in French loanwords are written with a single except when a schwa follows.

Vowel length

Vowel length is always indicated but in different ways by using an intricate system of single and double letters.

Historical overview

possessed phonemic consonant length in addition to phonemic vowel length, with no correspondence between them. Thus, long vowels could appear in closed syllables, and short vowels could occur in open syllables. In the transition to early Middle Dutch, short vowels were lengthened when they stood in open syllables. Short vowels could now occur only in closed syllables. Consonants could still be long in pronunciation and acted to close the preceding syllable. Therefore, any short vowel that was followed by a long consonant remained short.
The spelling system used by early Middle Dutch scribes accounted for that by indicating the vowel length only when it was necessary. As the length was implicit in open syllables, it was not indicated there, and only a single vowel was written. Long consonants were indicated usually by doubling the consonant letter, which meant that a short vowel was always followed by at least two consonant letters or by just one consonant at the end of a word.
Later in Middle Dutch, the distinction between short and long consonants started to disappear. That made it possible for short vowels to appear in open syllables once again. Because there was no longer a phonetic distinction between single and double consonants, Dutch writers started to use double consonants to indicate that the preceding vowel was short even when the consonant had not been long in the past. That eventually led to the modern Dutch spelling system.

Checked and free vowels

Modern Dutch spelling still retains many of the details of the late Middle Dutch system. The distinction between checked and free vowels is important in Dutch spelling. A checked vowel is one that is followed by a consonant in the same syllable while a free vowel ends the syllable. This distinction can apply to pronunciation or spelling independently, but a syllable that is checked in pronunciation will always be checked in spelling as well.

Checked in neither: la-ten
Checked in spelling only: lat-ten
Checked in both: lat , lat-je

A single vowel that is checked in neither is always long/tense. A vowel that is checked in both is always short/lax. The following table shows the pronunciation of the same three-letter sequence in different situations, with hyphens indicating the syllable divisions in the written form, and the IPA period to indicate them in the spoken form:
Free is fairly rare and is mostly confined to loanwords and names, since in native words /i/ is usually written as. As tense is rare except before, free is likewise rare except before.
The same rule applies to word-final vowels, which are always long because they are not followed by any consonant. Short vowels, not followed by any consonant, do not normally exist in Dutch, and there is no normal way to indicate them in the spelling.

Double vowels and consonants

When a vowel is short/lax but is free in pronunciation, the spelling is made checked by doubling the following consonant, so that the vowel is kept short according to the default rules. That has no effect on pronunciation, as modern Dutch does not have long consonants:

ram-men
tel-len
tin-nen
kop-pen
luk-ken

When a vowel is long/tense but still checked in pronunciation, it is necessarily checked in spelling as well. A change is thus needed to indicate the length, which is done by doubling the vowel. Doubled does not occur.

raam , raam-de
teel , teel-de
koop , koop-sel
Luuk

A single indicates short and long e but is also used to indicate the neutral schwa sound in unstressed syllables. Because the schwa is always short, is never followed by a double consonant when it represents.

ap-pe-len
ge-ko-men
kin-de-ren

A word-final long is written , as an exception to the normal rules. That means that a word-final single will almost always represent a schwa.

jee , je
mee , me
, we
Exception:

Because the position of the stress in a polysyllabic word is not indicated in the spelling, that can lead to ambiguity. Some pairs of words are spelled identically, but represents either stressed or or unstressed, depending on how the stress is placed.

be-de-len or
ver-gaan-de or
Morphological alternations

The length of a vowel generally does not change in the pronunciation of different forms of a word. However, in different forms of a word, a syllable may alternate between checked and free depending on the syllable that follows. The spelling rules nonetheless follow the simplest representation, writing double letters only when necessary. Consequently, some forms of the same word may be written with single letters while others are written with double letters. Such alternations commonly occur between the singular and plural of a noun or between the infinitive and the conjugated forms of verbs. Examples of alternations are shown below. Note that free is spelled in native words:

Long/tense vowel	When free	When checked	Short/lax vowel	When checked	When free
	laten	laat		lat	latten
	leken	leek		lek	lekken
i	dieven	dief		til	tillen
	bonen	boon		bon	bonnen
	muren	muur		mus	mussen

There are some irregular nouns that change their vowel from short/lax in the singular to long/tense in the plural. Their spelling does not alternate between single and double letters. However, the sound becomes in the plural of such nouns instead of, which is reflected in the spelling.

dag , da-gen
stad , ste-den
weg , we-gen
schip , sche-pen
lot , ''lo-ten''
