A separable verb like opbellen ("to phone") is built from a particle (op) and a verb (bellen). The headache for learners is not what these verbs mean — it is where the particle goes, because it moves around depending on the clause. This page is the word-order companion to the separable verbs overview: that page covers what separable verbs are and how they form participles; this page covers one thing only — where the particle lands.
There are exactly three positions to learn, one per clause type. Once you can predict the particle's landing spot, separable verbs stop being a guessing game.
Position 1 — Main clause: the particle goes to the very end
In an ordinary main clause with a single finite verb, the separable verb splits. The verb stem takes its normal second position (V2), and the particle is flung all the way to the end of the clause — it becomes the right arm of the verb bracket (see The Verb Bracket).
| Slot 1 | Verb stem (V2) | Middle field | Particle (end) |
|---|---|---|---|
| Ik | bel | je morgen | op. |
| Zij | ruimt | de keuken | op. |
| We | komen | om acht uur | aan. |
Ik bel je morgen om vijf uur op.
I'll phone you tomorrow at five o'clock. The stem 'bel' is in second position; the particle 'op' is flung to the very end.
Zij ruimt na het eten altijd de keuken op.
She always tidies the kitchen after dinner. 'ruimt' second, particle 'op' at the end.
De trein komt over tien minuten aan.
The train arrives in ten minutes. 'komt' second, particle 'aan' last.
The particle can end up far from its verb
This is the part that has no English parallel. Because the whole middle field sits between the stem and the particle, the particle can be many words away from the verb it belongs to. The longer the middle field, the more dramatic the stretch.
Ik bel je vanavond na het eten nog even op.
I'll give you a quick call tonight after dinner. Look how far the particle 'op' has travelled from its stem 'bel' — five words apart, yet they're one verb.
Hij haalt zijn kinderen elke dag om half vier van school af.
He picks his kids up from school every day at half past three. The particle 'af' lands at the very end, far from 'haalt'.
In English, "phone up" stays together: I'll phone you up tonight. The particle never wanders to the far end of the clause. In Dutch it routinely does — and recognising that a stranded op, aan, af, or uit at the clause's end belongs to a verb back in second position is a core listening and reading skill.
Position 2 — With an extra verb: the particle re-attaches to the infinitive
As soon as you add a second verb — a modal (willen, moeten, kunnen) or an auxiliary — the separable verb appears as an infinitive at the end of the clause. And in the infinitive, the particle glues back on: the whole thing is written as one word at the bracket's right arm.
Ik wil je straks even opbellen.
I want to give you a quick call later. With the modal 'wil', the verb is an infinitive — so the particle re-attaches: 'opbellen', one word, at the end.
We moeten de hele zolder nog opruimen.
We still have to tidy the whole attic. After 'moeten', the infinitive 'opruimen' is whole, at the end.
De gasten zullen rond acht uur aankomen.
The guests will arrive around eight. After 'zullen', 'aankomen' is one word at the end.
So the same verb is split when it is the only verb (Ik bel je op) but whole when it rides as an infinitive behind a modal (Ik wil je opbellen). The trigger is simple: a finite separable verb splits; an infinitive separable verb stays glued.
Position 3 — Subordinate clause: whole, at the end
In a subordinate clause, the entire verb goes to the end (see Verb-Final Order in Subordinate Clauses). Since the verb is already heading to the back, the particle has no reason to fly off on its own — it stays glued, and the whole verb is written as one word at the clause's end.
Ik hoop dat je me morgen opbelt.
I hope you'll call me tomorrow. In the subordinate clause the verb 'opbelt' is whole, at the end — not 'op...belt'.
Hij zegt dat hij elke avond de keuken opruimt.
He says he tidies the kitchen every evening. 'opruimt' is one word at the end of the dat-clause.
Weet jij of de trein op tijd aankomt?
Do you know whether the train arrives on time? In the embedded question, 'aankomt' stays glued at the end.
For the morphological detail of why this happens — and the participle forms — see separable verbs in subordinate clauses.
The three positions side by side
The same verb, opbellen, shows all three placements:
| Clause type | Example | Particle |
|---|---|---|
| Main clause (finite) | Ik bel je morgen op. | Detached, at the end |
| With a modal/auxiliary | Ik wil je morgen opbellen. | Attached to the infinitive, at the end |
| Subordinate clause | ...dat ik je morgen opbel. | Attached, at the end |
The unifying logic: the particle always ends up at the end of the clause. The only question is whether it travels there alone (detached, in a finite main clause) or glued to its verb (in an infinitive or a subordinate clause). Spelling follows: glued in the infinitive (opbellen), in the participle (opgebeld), and in the subordinate-final form (...dat ik opbel); detached at a main clause's end (bel ... op).
A note on pronouns and the middle field
Object pronouns sit early in the middle field, well to the left of the stranded particle (see object pronouns). So you get Ik bel *je morgen op* — the pronoun je up front, the particle op stranded at the end. Never let the pronoun drift toward the particle: it belongs near the verb, not near the particle.
Ik haal je om zes uur af.
I'll pick you up at six. The pronoun 'je' sits early; the particle 'af' is stranded at the end.
Common Mistakes
❌ Ik opbel je morgen.
Incorrect — the particle is kept glued to the finite verb, as in English 'I phone-up you'. A finite separable verb must split.
✅ Ik bel je morgen op.
I'll phone you tomorrow. The particle 'op' detaches and goes to the end.
❌ Ik bel op je morgen.
Incorrect — the particle 'op' is left stuck behind the stem instead of travelling to the end.
✅ Ik bel je morgen op.
I'll phone you tomorrow. The particle lands at the very end, after the middle field.
❌ Ik denk dat hij me morgen op belt.
Incorrect — the particle is split off inside a subordinate clause, where it must stay glued.
✅ Ik denk dat hij me morgen opbelt.
I think he'll call me tomorrow. In a subordinate clause the verb is whole at the end: 'opbelt'.
❌ Ik wil je op bellen.
Incorrect — the particle is detached from the infinitive; an infinitive separable verb is one word.
✅ Ik wil je opbellen.
I want to phone you. With a modal, the infinitive 'opbellen' is glued, at the end.
❌ De trein aankomt om negen uur.
Incorrect — a finite separable verb in a main clause must split: stem second, particle last.
✅ De trein komt om negen uur aan.
The train arrives at nine. 'komt' second, particle 'aan' at the end.
Key Takeaways
- A separable particle always lands at the end of the clause — the only question is whether it travels there alone or glued.
- Main clause (finite verb): the verb splits; the particle detaches and goes to the very end (bel ... op).
- With a modal/auxiliary: the verb is an infinitive, so the particle re-attaches (opbellen) at the end.
- Subordinate clause: the verb goes to the end whole, particle glued (...dat ik opbel).
- The particle can end up many words away from its stem in a main clause (Ik bel je vanavond na het eten nog even op) — a stretch with no English parallel.
- Spelling: attached in infinitive/participle/subordinate-final (opbellen, opgebeld, ...dat ik opbel), detached at a main-clause end (bel ... op).

Each has a stressed and an unstressed form (mij/me, jou/je, hem/'m, haar/'r), and the notorious hen/hun split is a 17th-century invention that natives freely ignore.
