There's a small rule in Dutch that English speakers break constantly without noticing: after a number, a unit of measure stays singular. You buy twee kilo appels (two kilo of apples), wait drie uur (three hours), pay vijf euro (five euros) — no plural ending in sight. English pluralizes nearly all of these ("two kilos, three hours, five euros"), so the habit of not pluralizing has to be consciously built. This page covers which nouns behave this way, why, and the cluster of everyday quantity words — een paar, een beetje, een stuk of tien — that you'll use far more often than exact figures.
The core rule: number + unit = singular
When a counted noun is a unit of measurement — weight, volume, length, time, money, or certain counting units — it does not take a plural ending after a number greater than one. The number already tells you there are several; the unit itself stays in its base form.
| Category | Dutch | English |
|---|---|---|
| Weight | twee kilo, honderd gram | two kilos, a hundred grams |
| Time | drie uur, tien jaar, drie kwartier | three hours, ten years, three quarter-hours |
| Money | vijf euro, twintig cent | five euros, twenty cents |
| People (counting) | vier man | four people / a team of four |
| Length | twee meter | two metres |
Doe maar twee kilo aardappelen, alstublieft.
Two kilos of potatoes, please. (kilo stays singular)
Dat kost vijf euro vijftig.
That costs five euros fifty. (euro stays singular)
Ik heb tien jaar in Utrecht gewoond.
I lived in Utrecht for ten years. (jaar stays singular for duration)
Why this happens — and where the line is
The logic is that these nouns function as measure phrases, not as ordinary countable objects. Twee kilo appels parses as "two-kilo's-worth of apples" — kilo is a measuring scoop, used once per unit, so Dutch leaves it in its bare measuring form. The same instinct exists faintly in English ("a five-foot fence," "a two-hour delay"), but Dutch applies it across the board.
The contrast is sharp when you compare a measure use with an ordinary countable use of the same word. Take jaar:
Mijn opa is vijfentachtig jaar.
My grandpa is eighty-five years old. (age = duration → jaar, singular)
In de komende jaren verandert er veel.
A lot will change in the coming years. (jaren = real plural, here it's not counted as a unit after a number)
So jaar stays singular when you count years as a measure ("ten years," "eighty-five years old"), but appears as the true plural jaren when it's an ordinary noun not directly counted (de jaren tachtig, "the eighties"; door de jaren heen, "over the years"). The same split holds for uur (counted: drie uur; general plural: de openingsuren).
Ordinary, non-measure nouns do pluralize normally after a number, exactly like English:
Er stonden drie auto's voor de deur.
There were three cars outside. (auto = ordinary noun → plural auto's)
Ik heb vijf appels gekocht.
I bought five apples. (ordinary count noun → plural)
So the rule is narrow and specific: units of measure stay singular; everything else pluralizes.
Vier man: counting people
A special idiom: when counting people as a group or workforce, Dutch uses man in the singular — vier man, tien man — meaning "four people," "ten people." It's the same logic as English "a crew of twelve hands" or "a ten-man team." This is informal-to-neutral and extremely common.
We waren met z'n zessen, dus zes man aan tafel.
There were six of us, so six people at the table.
Quantity words: when you don't have an exact number
Most of the time you don't say an exact figure — you say "a few," "a bit," "loads." Here's the everyday kit.
een paar — a few / a couple. Note: despite paar literally meaning "pair," een paar almost never means exactly two. It means a small handful, typically three to five. Only with an explicit object (een paar schoenen = a pair of shoes) does it mean a literal two.
Ik blijf nog een paar dagen.
I'm staying a few more days. (een paar = several, not literally two)
een beetje — a little / a bit (for uncountable things).
Wil je nog een beetje melk in je thee?
Do you want a little more milk in your tea?
veel / weinig — much, many / few, little. genoeg — enough. te veel / te weinig — too much / too little.
Er is genoeg eten voor iedereen, maar te weinig stoelen.
There's enough food for everyone, but too few chairs.
een stuk of tien — "about ten," "ten-ish." This handy frame, een stuk of + a round number, gives an estimate. Een stuk of twintig mensen = "twenty-odd people."
Er kwamen een stuk of dertig gasten op het feest.
About thirty guests came to the party. (een stuk of dertig = thirtyish)
tientallen / honderden / duizenden — "dozens / hundreds / thousands of," used for vague large quantities. enkele (a few, somewhat formal), sommige (some, of a set).
Tientallen demonstranten verzamelden zich op het plein.
Dozens of protesters gathered on the square. (formal/journalistic register)
Common Mistakes
❌ Dat kost drie euro's.
Incorrect — money units stay singular: 'drie euro', never 'euro's'.
✅ Dat kost drie euro.
That costs three euros.
❌ Ik heb hier tien jaren gewoond.
Incorrect for duration — counted years stay singular: 'tien jaar'.
✅ Ik heb hier tien jaar gewoond.
I lived here for ten years.
❌ Geef me twee kilo's tomaten.
Incorrect — 'kilo' is a measure and stays singular: 'twee kilo'.
✅ Geef me twee kilo tomaten.
Give me two kilos of tomatoes.
❌ Er waren maar een paar, precies twee, gasten.
Misleading — 'een paar' means 'a few', not exactly two; for exactly two say 'twee'.
✅ Er waren maar twee gasten.
There were only two guests.
❌ De film duurt twee uren.
Incorrect — counted hours stay singular: 'twee uur'.
✅ De film duurt twee uur.
The film lasts two hours.
Key Takeaways
- After a number, units of measure stay singular: twee kilo, drie uur, vijf euro, tien jaar, vier man.
- The same word can pluralize when it's an ordinary noun, not a counted measure: tien jaar (duration) vs de jaren tachtig (the eighties).
- Ordinary count nouns pluralize normally: drie auto's, vijf appels.
- een paar = a few (not literally two, unless an object follows: een paar schoenen).
- Estimate with een stuk of
- a round number (een stuk of tien = about ten); vague large amounts with tientallen / honderden / duizenden.
