English has one word, because, and it never changes the rest of the sentence: "I'm staying home because I'm ill" has the same word order whether you say it that way or rearrange it. Dutch splits "because" into two words — want and omdat — and the catch is not really about meaning. Both translate as "because" and both give a reason. The catch is grammar: want and omdat belong to two different families of conjunctions, and each family bends the word order in its own way. Get the family wrong and the sentence breaks. This is the single most common word-order error English speakers make in Dutch, so it's worth getting cold.
The one rule that decides it
The choice is grammatical, not semantic. You decide based on what the conjunction does to the verb:
- want is a coordinating conjunction (like en, maar, of). It joins two equal main clauses. The verb after want stays in second position — normal main-clause order. And want can never begin a sentence.
- omdat is a subordinating conjunction. It opens a subordinate clause, which sends its verb all the way to the end. Omdat can begin a sentence — and when it does, the main clause that follows inverts (verb before subject).
Ik blijf thuis, want ik ben ziek.
I'm staying home, because I'm ill. — want: verb 'ben' is in second position.
Ik blijf thuis omdat ik ziek ben.
I'm staying home because I'm ill. — omdat: verb 'ben' is shoved to the very end.
Look at those two side by side. Same meaning, same words almost — but ik ben ziek (verb second) becomes ik ziek ben (verb last) the moment you swap want for omdat. That flip is the entire lesson. The comma before want is normal; before omdat it's optional and usually omitted.
Want: verb stays second, clause can't lead
Want treats the reason as a second, free-standing main clause tacked on to the first. Because it's a main clause, it keeps ordinary main-clause word order: the finite verb is the second element. Nothing moves.
We gaan nu weg, want het is al laat.
We're leaving now, because it's already late. — 'is' sits second, just like in any main clause.
Ze neemt de trein, want haar auto is kapot.
She's taking the train, because her car is broken. — main-clause order after want: 'is' second.
The hard restriction: want cannot start a sentence. Since it merely links two main clauses, there has to be something on its left. You can't answer a question or open a thought with Want…. If you want to lead with the reason, you must use omdat instead.
Hij eet geen vlees, want hij is vegetariër.
He doesn't eat meat, because he's a vegetarian. — perfectly natural; want links two main clauses.
There is a subtle nuance worth knowing: want often presents the reason as a justification or evidence for the speaker's statement ("…and here's how I know / here's my reasoning"), whereas omdat states a direct cause. Both are usually interchangeable in everyday speech, but in careful writing want leans toward "the reason I'm saying this" and omdat toward "the reason it happened." Don't overthink it at B1 — the word order is what matters.
Omdat: verb to the end, free to lead
Omdat opens a subordinate clause — a clause that depends on the main one. Dutch subordinate clauses send their finite verb to the end, after everything else. This is the same rule you've seen with dat, als, of, terwijl, and every other subordinator.
Ze is boos omdat je te laat bent gekomen.
She's angry because you arrived late. — the cluster 'bent gekomen' lands at the very end.
Ik kan niet komen omdat ik moet werken.
I can't come because I have to work. — 'moet werken' goes last.
Unlike want, omdat can begin the sentence — and this is genuinely useful, because it's how you answer the question Waarom? ("Why?") in full sentences and how you front the reason for emphasis. When the omdat-clause comes first, it fills the first slot of the main clause, so the main clause's verb must come immediately next, before its subject. This is Dutch inversion: the verb-second rule counts the whole subordinate clause as the "first element."
Omdat het regende, bleven we binnen.
Because it was raining, we stayed inside. — omdat-clause first, then inverted main clause: 'bleven we' (verb before subject).
Answering 'Waarom?'
This is the practical payoff. When someone asks Waarom? ("Why?"), the natural answer is a clause introduced by Omdat…, not Want…. Since want can't start a sentence, it's simply ungrammatical as a stand-alone reply.
— Waarom ben je zo moe? — Omdat ik vannacht niet geslapen heb.
— Why are you so tired? — Because I didn't sleep last night. — Omdat opens the answer; verb 'geslapen heb' goes last.
In very casual speech you'll occasionally hear people start with Want as a sloppy afterthought, but it's not standard and you should not imitate it. The clean, correct answer to Waarom? always begins with Omdat.
The two side by side
| want | omdat | |
|---|---|---|
| Conjunction type | coordinating | subordinating |
| Verb position in its clause | second (V2) | last (verb-final) |
| Can start the sentence? | no | yes |
| Can answer "Waarom?" | no | yes |
| Example | …, want ik ben ziek | omdat ik ziek ben |
There's a handy memory hook in the spelling: om-dat literally contains dat, and dat is the prototype subordinator that sends verbs to the end. So omdat behaves like dat — verb last. Want has no dat in it and behaves like a plain main clause — verb second.
Common Mistakes
These are the exact slips English speakers make, because English "because" doesn't touch word order at all.
❌ Ik blijf thuis, want ik ziek ben.
Incorrect — after want the verb stays second; it must be 'ik ben ziek', not 'ik ziek ben'.
✅ Ik blijf thuis, want ik ben ziek.
I'm staying home, because I'm ill.
❌ Ik blijf thuis omdat ik ben ziek.
Incorrect — after omdat the verb goes to the end: 'omdat ik ziek ben'.
✅ Ik blijf thuis omdat ik ziek ben.
I'm staying home because I'm ill.
❌ Want ik ben ziek, blijf ik thuis.
Incorrect — want can never start a sentence. Use omdat to lead with the reason.
✅ Omdat ik ziek ben, blijf ik thuis.
Because I'm ill, I'm staying home.
❌ — Waarom kom je niet? — Want ik moet werken.
Incorrect — you can't answer 'Waarom?' with want. The answer must begin with Omdat.
✅ — Waarom kom je niet? — Omdat ik moet werken.
— Why aren't you coming? — Because I have to work.
❌ Omdat het regende, we bleven binnen.
Incorrect — when the omdat-clause leads, the main clause inverts: verb before subject, 'bleven we'.
✅ Omdat het regende, bleven we binnen.
Because it was raining, we stayed inside.
Key Takeaways
- want = coordinating: verb stays second, clause can't start the sentence, can't answer Waarom?.
- omdat = subordinating: verb goes to the end, clause can start the sentence (then the main clause inverts), and is the natural answer to Waarom?.
- The choice is about grammar, not meaning — both translate "because." Pick the family, then apply its word-order rule.
- Spelling hook: omdat contains dat, so it throws the verb to the end like dat does.

- Of vs Als: 'If' = Whether or Condition?B1 — English 'if' does two jobs that Dutch keeps strictly apart. Of is 'whether' — it introduces an indirect yes/no question ('Ik weet niet of hij komt'). Als is 'if' in the conditional sense — it introduces a real condition ('Als het regent, blijf ik thuis'). The test is simple: if you could swap 'if' for 'whether', use of; if it states a condition, use als. This page gives the rule, head-to-head pairs, and the errors English speakers make most.
