^ abcdefGenerally, the southern varieties preserve the /f/–/v/, /x/–/ɣ/ and /s/–/z/ contrasts. Southern /x/, /ɣ/ may be also somewhat more front, i.e. post-palatal. In the north, these are far less stable: most speakers merge /x/ and /ɣ/ into a post-velar [x̠] or uvular [χ]; most Netherlandic Standard Dutch speakers lack a consistent /f/–/v/ contrast. In some accents, e.g. Amsterdam, /s/ and /z/ are also not distinguished./ʒ/ often joins this neutralization by merging with /ʃ/. In some accents, /ɦ/ is also devoiced to [h]. See also Hard and soft G in Dutch.
^The final ‹n› of the plural ending -en is usually not pronounced, except in the North East (Low Saxon) and the South West (East and West Flemish) where the ending becomes a syllabic [n̩] sound. The syllabic pronunciation is considered to be strongly non-standard, especially in the Netherlands.
^ abcDutch devoices all obstruents at the ends of words (e.g. a final /d/ becomes [t]). This is partly reflected in the spelling: the voiced ‹z› in plural huizen ('houses') becomes huis ('house') in singular, and duiven ('doves') becomes duif ('dove'). The other cases are always written with the voiced consonant, even though a devoiced one is actually pronounced: the voiced ‹d› in plural baarden[ˈbaːrdə(n)] ('beards') is retained in the singular spelling baard ('beard'), but pronounced as [baːrt]; and plural ribben[ˈrɪbə(n)] ('ribs') has singular rib, pronounced as [rɪp]. Because of assimilation, often the initial consonant of the next word is also devoiced, e.g. het vee ('the cattle') is [ɦət ˈfeː]
^The realization of the /ʋ/ phoneme varies considerably from the Northern to the Southern and Belgium dialects of the Dutch language. In the north of the Netherlands, it is a labiodental approximant[ʋ]. In the south of the Netherlands and in Belgium, it is pronounced as a bilabial approximant[β̞] (as it also is in the Hasselt and Maastricht dialects), and Standard Belgian Dutch uses the labiovelar approximant[w].
^ abcThe alveolo-palatal stops [c] and [ɟ] and nasal[ɲ] are allophones of the sequences /tj/, /dj/ and /nj/. [ɟ] occurs only in loanwords. [ɲ] also occurs as an allophone of /n/ before /tj/ (realized as [c]).
^/ɡ/ is not a native phoneme of Dutch and only occurs in loanwords, like goal or when /k/ is voiced, like in zakdoek[ˈzɑɡduk].
^ abPhonemically, [ʃ] and [ʒ] are /sj, zj/. They occur both in native words such as huisje[ˈɦœyʃə] and in loanwords such as show[ʃoː] and bagage[baːˈɣaːʒə]
^The glottal stop[ʔ] is not a separate phoneme in Dutch and is indicated sparingly in Dutch transcriptions on Wikipedia. It is mandatorily inserted between [aː] and [ə] and a syllable-initial vowel, both within words and at word boundaries. Often, it is also inserted before phrase-initial vowels and before any word-initial vowel. This is not indicated in most of our transcriptions.
^When the penultimate syllable is open, stress may fall on any of the last three syllables. When the penultimate syllable is closed, stress falls on either of the last two syllables. While stress is phonemic, minimal pairs are rare. For example vóórkomen/ˈvoːrkoːmə(n)/ "to occur" and voorkómen/voːrˈkoːmə(n)/ "to prevent". In composite words, secondary stress is often present. Marking the stress in written Dutch is optional, never obligatory, but sometimes recommended.
^ abThe "checked" vowels /ɑ/, /ɛ/, /ɪ/, /ɔ/, and /ʏ/ occur only in closed syllables, while their "free" counterparts /aː/, /eː/, /i/, /oː/, and /y/ can occur in open syllables (as can the other vowels). These two sets also go by the names dull/sharp, dim/clear, lax/tense, closed/open, or short/long. One of each pair is pronounced slightly longer by many speakers, so the terms long and short traditionally used to explain the use of doubled consonants and vowels in the orthographic system. Differences in vowel length tend to be bigger in southern dialects; in extreme cases, when lax vowels become as tense as the tense vowels, the vowel length is the only difference between them.
^ abcFor most speakers of Netherlandic Standard Dutch, the long close-mid vowels /eː/, /øː/ and /oː/ are realised as slightly closing diphthongs [eɪ], [øʏ] and [oʊ], unless they precede /r/ within the same syllable. The closing diphthongs also appear in certain Belgian dialects, e.g. the one of Bruges, but not in Belgian Standard Dutch. See Dutch phonology#Monophthongs for more details.
^ abcThe exact quality of diphthongs varies; Netherlandic Standard Dutch has somewhat more open (in case of /ʌu/ and often /œy/ also unrounded) first elements: [æi], [ɐy], [ɑu]. In Belgian Standard Dutch, they begin in the open-mid region, and the last diphthong has a rounded first element: [ɛi], [œy], [ɔu]. In Belgium, the onset of /œy/ can also be unrounded to [ɐy]. Some non-standard dialects (e.g. many southern dialects) realise these diphthongs as either narrow diphthongs or (as in The Hague dialect) long monophthongs. See Dutch phonology § Diphthongs for more details.
