Dutch plurals: -en or -s?
Almost every Dutch noun forms its plural with one of two endings: -en or -s. The default is -en; -s is used for a predictable set of words. The complications are not the endings themselves but the spelling changes that -en triggers, plus a short list of irregulars worth memorising.
The default: -en
Most Dutch nouns take -en. This is the safe guess when you do not know a word's plural. The ending is written -en but pronounced as a bare schwa in most of the Netherlands — boeken sounds like "boeke", with the final n dropped in ordinary speech. In careful speech, in song, and in much of Belgium the n is pronounced. Either way you always write the full -en.
| Singular | Plural | English |
|---|---|---|
| het boek | boeken | book(s) |
| de trein | treinen | train(s) |
| de fiets | fietsen | bike(s) |
| de tafel | tafels | table(s) |
Note the last row: tafel takes -s, not -en, because it ends in an unstressed syllable — a pattern covered below. Also note that plurals are always de-words: a singular het-noun becomes de in the plural (het boek → de boeken). That fact matters for adjective endings.
Spelling changes with -en
Dutch spelling keeps vowel length consistent between singular and plural, so adding -en often forces a change. These are regular and predictable once you know the open/closed syllable logic explained under long vs short vowels.
| Singular | Plural | What happened |
|---|---|---|
| maan | manen | long vowel: drop one a (open syllable keeps it long) |
| man | mannen | short vowel: double the consonant to keep it short |
| brief | brieven | final f → v |
| huis | huizen | final s → z |
| glas | glazen | short vowel lengthens: s → z, single a |
The f→v and s→z shifts happen because Dutch does not allow those voiced consonants at the end of a word, but does allow them between vowels. The glas → glazen type looks irregular but simply combines two regular rules at once.
When to use -s instead
The -s plural is used for well-defined groups. Learn these categories and you can predict most -s plurals:
| Category | Examples |
|---|---|
| Words ending in unstressed -el, -em, -en, -er, -aar | tafel → tafels, bezem → bezems, deken → dekens, meter → meters |
| Words ending in unstressed -e or -je (diminutives) | tante → tantes, meisje → meisjes |
| Many loanwords, especially from English/French | computer → computers, baby → baby's, film → films |
| Words ending in a long vowel | auto → auto's, menu → menu's, taxi → taxi's |
All diminutives (the everywhere-present -je words) take -s, which is one reason the ending is so common in speech.
The apostrophe before -s. When a word ends in a single long vowel written with one letter (a, o, u, i, y), insert an apostrophe so the vowel stays long: auto's, foto's, baby's, hobby's. But words ending in -e take a plain -s with no apostrophe: tantes, garages. This same apostrophe appears in the possessive of these words too.
The -eren group
A small, closed set of neuter nouns forms the plural with -eren — a fossil of an old Germanic plural, the same one behind English "child → children". You cannot predict these; just memorise the handful you will actually use:
| Singular | Plural | English |
|---|---|---|
| kind | kinderen | child(ren) |
| ei | eieren | egg(s) |
| blad | bladeren | leaf/leaves |
| lied | liederen | song(s) |
| volk | volkeren | people(s)/nation(s) |
Note that blad has two plurals with a meaning split: bladeren for leaves on a tree, but bladen for sheets of paper or magazines.
Latin and Greek plurals
Learned words borrowed from Latin or Greek often keep a classical plural, though many now also have an accepted -s form.
| Singular | Plural | English |
|---|---|---|
| museum | musea (or museums) | museum(s) |
| medium | media | medium/media |
| politicus | politici | politician(s) |
| catalogus | catalogi | catalogue(s) |
| crisis | crises | crisis/crises |
Vowel-change and other irregulars
A few high-frequency nouns lengthen their vowel in the plural (a leftover of an older short/long alternation). Historically these words had a long vowel that shortened in the singular, and the plural preserves the original length. Because they turn up constantly — you cannot get through a day of Dutch without dagen or steden — you will absorb them without deliberate study:
| Singular | Plural | English |
|---|---|---|
| stad | steden | city/cities |
| schip | schepen | ship(s) |
| dag | dagen | day(s) |
| weg | wegen | road(s) |
| lid | leden | member(s) |
A handful of words simply have no plural, or a suppletive one: de mens ("human") pluralises as de mensen ("people"), while de man uses mannen normally but man unchanged after numbers in fixed expressions (met z'n vieren). These are edge cases you can safely pick up later.
Common mistakes. Two errors dominate. First, forgetting the consonant-doubling or vowel-dropping spelling change — writing mannnen or manen for "men" instead of mannen, or maanen instead of manen for "moons". Second, adding -en to words that want -s: computeren, tafelen. When a word ends in an unstressed syllable, reach for -s. There is no Belgian/Netherlands split here — plural formation is identical across the whole language area. More slips are gathered under common mistakes learners make.
Because plurals feed directly into other rules, it helps to read this alongside de or het (all plurals are de-words) and adjective endings (plurals always trigger the -e). The nouns in the family and food vocabulary lists give the plural for every entry so you can practise the patterns above.
