of
Or
Use of to offer a choice between two things (or) or to introduce an indirect question (whether/if).
How It Works
The word of is one of the most versatile words in Dutch. It serves several distinct grammatical roles:
1. Coordinating Conjunction ('Or'):
In this role, it connects two nouns, adjectives, or entire main clauses. When connecting two main clauses, it occupies 'position zero', meaning the standard main clause word order (Subject + Verb) remains the same.
Example: Wil je koffie of thee?
2. Correlative Conjunction ('Either... or...'):
To emphasize a choice between two options, you can use of... of... at the start of each part.
Example: Of we gaan nu, of we gaan helemaal niet. (Either we go now, or we don't go at all.)
3. Subordinating Conjunction ('Whether' / 'If'):
When used to report a question or express uncertainty, of functions like the English 'whether'. Crucially, this triggers subordinate clause word order, meaning the conjugated verb moves to the very end.
The Whether Test: If you can replace 'if' with 'whether' in English, use of. If you cannot (because it is a condition), use als. A related word is alsof, which means 'as if'.
4. Common Phrases:
Dutch speakers frequently use of niet? at the end of a sentence to create a tag question (e.g., Je komt toch, of niet?). Another common filler is of zo, which means 'or something' (e.g., Heb je honger of zo?).
Important Note: Do not confuse of with the English word 'of'. To show possession or origin in Dutch, you must use van.
Examples (6)
- Wil je water of sap?
Do you want water or juice?
Word by Word: Want you water or juice?
Here, 'of' acts as a simple coordinator between two nouns.
- Gaan we nu of wachten we nog even?
Are we going now or are we waiting a bit longer?
Word by Word: Go we now or wait we yet a-moment?
When connecting two main clauses, the word order in both remains Main Clause (V2) word order.
- Ik vraag me af of het gaat regenen.
I wonder whether it is going to rain.
Word by Word: I ask me off whether it goes rain.
In this indirect question, 'of' means 'whether' and the verb 'gaat' moves toward the end.
- Kom je naar het feest, of niet?
Are you coming to the party, or not?
Word by Word: Come you to the party, or not?
Adding 'of niet?' at the end of a sentence is a common way to form a tag question, similar to 'right?' or 'isn't it?'.
- Wil je een appel of zo?
Do you want an apple or something?
Word by Word: Want you an apple or so?
The phrase 'of zo' is very common in spoken Dutch and means 'or something' or 'or whatever'.
- Of we gaan vandaag, of we gaan morgen.
Either we go today, or we go tomorrow.
Word by Word: Or we go today, or we go tomorrow.
Using 'of... of...' is the Dutch way to say 'either... or...'.
Common Mistakes
Using 'als' instead of 'of' for indirect questions.
Ik weet niet als hij komt.Ik weet niet of hij komt.Use the 'Whether Test': if you can replace 'if' with 'whether' in English, you must use 'of' in Dutch. Use als only for conditions (If X, then Y).
Using 'of' to show possession (English 'of' trap).
De auto of mijn vader.De auto van mijn vader.Dutch 'of' never means possession. Use van to translate the English 'of' in phrases like 'the car of my father'.
Incorrect word order after 'of' (whether).
Ik weet niet of hij is thuis.Ik weet niet of hij thuis is.When 'of' means 'whether', it starts a subclause, so the verb 'is' must move to the end.
How It Connects
Learn This First
The conjunction 'of' is a foundational coordinating conjunction used to present alternatives. To understand its use, a learner should first be familiar with basic nouns and the concept of linking words, similar to how 'en' (and) is used.

Level 3 - vanOf/From
A 'false friend' for English speakers; 'van' is used for possession, not 'of'.
