There is a written error so characteristically English that Dutch has a name for it: de Engelse ziekte, "the English disease." English writes noun compounds as a string of separate words — taxi driver, credit card, bus stop — and English speakers learning Dutch carry that habit straight over, writing taxi chauffeur, credit card, bus halte. In Dutch this is simply wrong. Dutch compounds are solid single words: taxichauffeur, creditcard, bushalte. The space isn't a stylistic choice; it changes or destroys the meaning, because two separate words read as a different grammatical structure. This page drills the solid-compound rule and the linking letters (the tussen-s and tussen-n) that hold long compounds together.
The core rule: one concept, one word
A Dutch compound noun names a single concept built from two (or more) parts, and Dutch signals "single concept" by writing it as one unbroken word, however long. The last part is the head — it decides the gender and the plural — and everything before it modifies it. Een taxichauffeur is one thing (a taxi driver); writing een taxi chauffeur reads as two nouns awkwardly next to each other and looks, to a Dutch reader, like a typo or a foreigner's mistake.
❌ taxi chauffeur
Incorrect — written as two words, English-style.
✅ taxichauffeur
taxi driver — one solid word.
❌ bus halte
Incorrect — split compound.
✅ bushalte
bus stop.
Ik wacht al tien minuten bij de bushalte op de taxichauffeur.
I've been waiting at the bus stop for the taxi driver for ten minutes. Both compounds are solid.
Why the space changes the meaning
This isn't pedantry — the space genuinely shifts what the phrase says. Consider the classic pair. Een rode wijnglas and een rodewijnglas are different things. Rodewijnglas (red-wine glass) is a glass for red wine; the compound rodewijn modifies glas. Write rode wijnglas with a space and rode now modifies wijnglas, giving "a red wine-glass" — a wine glass that happens to be red. The reader cannot recover your intended meaning; the spacing is the grammar.
een rodewijnglas
a red-wine glass — a glass meant for red wine ('rodewijn' modifies 'glas').
een rood wijnglas
a red wine-glass — a wine glass that is red ('rood' modifies 'wijnglas'). Different object entirely.
Linking letters: the tussen-s and tussen-n
Many Dutch compounds insert a connecting letter between the parts — a tussen-s (-s-) or a tussen-n (-en-). These are part of the single word, never a reason to split it. Two practical guidelines:
- Tussen-s: insert it when you naturally hear an /s/ between the parts. staat + hoofd → staatshoofd (head of state), dorp + plein → dorpsplein (village square). There's no perfect rule — pronunciation is the best guide, and you confirm against a dictionary or Het Groene Boekje.
- Tussen-n: spelled -en-, used mainly when the first part is a noun whose plural ends in -en and has no plural in -s. pannenkoek (pancake, from pannen), boekenkast (bookcase, from boeken), krantenwinkel (newsagent, from kranten).
Het staatshoofd opende het nieuwe dorpsplein.
The head of state opened the new village square. Two tussen-s compounds — still one word each.
Zet de pannenkoeken maar in de boekenkast — grapje.
Put the pancakes in the bookcase then — joke. Two tussen-n compounds: 'pannenkoek', 'boekenkast'.
❌ pannen koeken / boeken kast
Incorrect — the linking -en- is part of one word, not a seam to split on.
✅ pannenkoeken / boekenkast
pancakes / bookcase — solid words.
When a hyphen IS correct
Dutch closes compounds solid by default, but a hyphen is used in a few specific situations — and only those. It is not a license to drift back toward English spacing.
- Vowel clashes that would misread: auto-ongeluk (car accident — without the hyphen, autoongeluk runs three vowels together), zee-egel (sea urchin), na-apen (to ape/mimic).
- Compounds with names, letters, or numbers: Rijn-Schelde, A4-papier, sms-bericht.
- Coordinated parts: taal- en letterkunde (language and literature studies), where the shared head is shown once.
Hij raakte gewond bij een auto-ongeluk.
He was injured in a car accident. Hyphen prevents the triple-vowel pile-up 'autoo-'.
Ze studeert taal- en letterkunde.
She studies language and literature. The hyphen after 'taal-' shows the shared head 'kunde'.
A few high-frequency ones to fix in your writing
These are the compounds English speakers most often split, because their English equivalents are two words:
| English (two words) | Wrong (split) | Right (solid) |
|---|---|---|
| credit card | credit card | creditcard |
| two-person bed | twee persoons bed | tweepersoonsbed |
| debit/PIN card | pin pas | pinpas |
| train station | trein station | treinstation |
| mobile phone | mobiele telefoon nummer | mobiele telefoonnummer (adj + solid noun) |
Note the last row: an adjective before a compound stays separate (it modifies the whole compound), but the noun telefoonnummer is itself solid. So mobiele telefoonnummer keeps one space (after the adjective) and closes the rest.
Wat is je mobiele telefoonnummer?
What's your mobile phone number? Adjective 'mobiele' is separate; 'telefoonnummer' is one word.
Common Mistakes
❌ taxi chauffeur
Incorrect — split like English 'taxi driver'.
✅ taxichauffeur
taxi driver.
❌ twee persoons bed
Incorrect — three separate words for one concept.
✅ tweepersoonsbed
double bed (two-person bed) — solid, with the tussen-s in 'tweepersoons'.
❌ pin pas
Incorrect — split compound.
✅ pinpas
debit/PIN card.
❌ auto ongeluk
Incorrect — split; and simply gluing it ('autoongeluk') misreads, so a hyphen is required.
✅ auto-ongeluk
car accident — hyphen for the vowel clash.
❌ verjaardags feest
Incorrect — split; the tussen-s belongs inside one word.
✅ verjaardagsfeest
birthday party — solid, with tussen-s.
Key Takeaways
- Dutch noun compounds are solid single words, no matter how long. Splitting them is de Engelse ziekte, the most visible written anglicism.
- The space is not optional: rodewijnglas (red-wine glass) ≠ rood wijnglas (red wine-glass). Spacing changes meaning.
- Many compounds carry a linking letter: tussen-s (staatshoofd, dorpsplein) heard as an /s/, or tussen-n spelled -en- (pannenkoek, boekenkast). These stay inside the one word.
- Use a hyphen only for vowel clashes (auto-ongeluk), names/letters/numbers (sms-bericht), and coordinated parts (taal- en letterkunde).
- An adjective before a compound stays separate (mobiele telefoonnummer) — only the noun compound itself closes up.
