The Infinitive as Instruction (Niet roken)

Walk through any Dutch railway station, public building or kitchen and you'll meet a verb form English doesn't have: the bare infinitive used as a command. Niet roken ("No smoking"), Deur sluiten ("Close the door"), Hier aanbellen ("Ring here"), Roeren tot het kookt ("Stir until it boils"). Where English uses "No smoking", a bare imperative ("Close the door"), or a noun phrase, Dutch reaches for the plain infinitiveroken, sluiten, aanbellen — placed at the end after its objects and adverbs. This is not a quirk to file under "odd signs you'll see." It is a whole register: the impersonal, addressee-neutral style of officialdom, public notices, manuals and recipes. Recognizing it — and knowing when to write in it — is what this page is about.

The form: bare infinitive, objects first

The instruction infinitive is just the dictionary form of the verb. What's distinctive is the word order: any object, place or manner phrase comes first, and the infinitive lands at the end of the line.

Niet roken.

No smoking. — bare infinitive 'roken' with 'niet'.

Niet aanraken.

Do not touch. — typical museum/exhibit sign.

Deur sluiten.

Close the door. — object 'deur' first, infinitive 'sluiten' last.

Hier aanbellen.

Ring here. — place 'hier' first, then the infinitive.

The negation niet (or niet + a noun) sits in front, just as you'd expect from a verb-final clause. The effect is terse and depersonalized: there's no u or je, no "please", nobody addressed at all. The instruction simply states what is (not) to be done.

Why an infinitive and not an imperative?

Dutch has an imperative — Sluit de deur!, Bel hier aan! — so why do signs avoid it? Because the imperative addresses a specific person. It points a finger: you, do this. That's perfect in conversation, but on a sign or in a recipe there is no specific addressee — the message is for anyone, everyone, no one in particular. The infinitive is addressee-neutral: it names the action without aiming it at a person. That neutrality is exactly the tone officialdom and instructions want.

Bij brand niet de lift gebruiken.

In case of fire, do not use the lift. — impersonal, for anyone who reads it.

Eerst lezen, dan invullen.

Read first, then fill in. — sequence of impersonal instructions on a form.

💡
The split is imperative = spoken, to a person vs infinitive = written, to no one in particular. Sluit de deur is what you say to your flatmate; Deur sluiten is what the sign on the door says. Same instruction, different register. See verbs/imperative/alternatives for the full range of ways Dutch gives commands.

This is also why the infinitive feels colder than the imperative. A spoken Sluit de deur, alsjeblieft is a polite request to a friend; a posted Deur sluiten is a rule. Using the wrong one jars: barking Roken niet! at a guest sounds like you're reading them a regulation, while writing Rook hier niet, alsjeblieft on an official sign sounds oddly chatty.

Separable verbs stay whole

Because the instruction form is a true infinitive, separable verbs do not split — the prefix stays attached, unlike in a finite clause or an imperative.

Niet openmaken.

Do not open. — separable 'openmaken' stays one word; not 'maak niet open'.

Pakje hier ophangen.

Hang the package here. — separable 'ophangen' whole, object first.

Compare the imperative, where the prefix flies to the end: Maak het pakje niet open! On a sign, that becomes the tidy infinitive Niet openmaken. This is the same whole-word behaviour you see in the nominalized infinitive (verbs/infinitive/nominalized): with no finite verb in the clause, there is nothing to push the prefix away.

The recipe register

Recipes are the other heartland of the instruction infinitive. Step by step, a Dutch recipe lists actions as bare infinitives, objects and quantities first.

200 gram suiker toevoegen en mengen.

Add 200 grams of sugar and stir. — quantities first, infinitives 'toevoegen' and 'mengen' at the end.

Roeren tot het kookt.

Stir until it boils. — 'roeren' as a step instruction.

De oven voorverwarmen op 180 graden.

Preheat the oven to 180 degrees. — separable 'voorverwarmen' whole, object first.

Laten afkoelen en daarna in de koelkast bewaren.

Let it cool and then keep it in the fridge. — chained infinitive instructions.

Modern recipes do sometimes use the u-imperative instead (Voeg 200 gram suiker toe) for a warmer, more direct tone — cookbooks aimed at home cooks lean this way. But the infinitive remains the neutral, classic recipe style, and you will read it constantly. (Both registers coexist; the infinitive is the more impersonal of the two.) See register/instructional-and-recipes for more on this written style.

The one-word door signs

A handful of single-infinitive signs are worth memorizing as vocabulary, because you'll meet them daily and they look nothing like their English equivalents:

Dutch signEnglish
TrekkenPull (on a door)
DuwenPush (on a door)
Niet rokenNo smoking
Niet storenDo not disturb
Niet parkerenNo parking
AanbellenRing (the bell)

Op de deur stond 'Duwen', maar iedereen bleef trekken.

The door said 'Push', but everyone kept pulling. — 'Duwen'/'trekken' as door instructions.

Note that Trekken and Duwen are infinitives, not imperatives — English's "Pull"/"Push" happen to be identical to its imperative, which hides the difference, but in Dutch the form is unmistakably the infinitive.

Common Mistakes

❌ Alstublieft sluit de deur als u weggaat.

Wrong register for a sign — a notice uses the impersonal infinitive, not a polite full sentence.

✅ Deur sluiten.

Close the door. — the standard sign form.

❌ Maak niet open.

Incorrect for a sign — the instruction infinitive keeps separable verbs whole: 'Niet openmaken'.

✅ Niet openmaken.

Do not open.

❌ Voeg 200 gram suiker toe en meng. (as a neutral recipe step)

Not wrong, but this is the imperative register; the classic neutral recipe uses infinitives.

✅ 200 gram suiker toevoegen en mengen.

Add 200 grams of sugar and stir.

❌ Rook niet hier.

Reads as a spoken command to a person; a sign uses the impersonal 'Niet roken'.

✅ Niet roken.

No smoking.

❌ Roken toevoegen 200 gram suiker.

Wrong order — objects and quantities come first, the infinitive last: '200 gram suiker toevoegen'.

✅ 200 gram suiker toevoegen.

Add 200 grams of sugar.

Key Takeaways

  • Dutch signs, notices and recipes use the bare infinitive as an impersonal command: Niet roken, Deur sluiten, Roeren tot het kookt.
  • The infinitive is addressee-neutral — it names an action without pointing at a specific person, unlike the imperative.
  • This is a full register (officialese, manuals, recipes), parallel to but distinct from the spoken imperative — call it the sign-and-recipe register.
  • Word order is objects/adverbs first, infinitive last: 200 gram suiker toevoegen.
  • Separable verbs stay whole: Niet openmaken, De oven voorverwarmen.
  • Trekken / Duwen on doors are infinitives, not imperatives — the English "Pull"/"Push" hides the distinction.
