Place a question inside another message
An indirect question presents information someone wants, lacks, or asks about inside a larger sentence. Compare Waar woont Noor? with Ik weet niet waar Noor woont. The direct question asks for a place; the larger sentence reports that the speaker does not know that place. The information gap is preserved, but the embedded clause uses dependent order. Do not copy the direct question unchanged after every introductory phrase.
The outer frame can itself be a question: Kunt u zeggen waar Noor woont? Here the finite verb kunt belongs to the request addressed to u, while woont belongs to the embedded subject Noor. Track these clauses separately. A question mark belongs to the whole utterance if the outer sentence asks something. A statement such as Ik vraag me af waar Noor woont normally ends with a period even though its embedded content concerns an unresolved question.
Use of for a yes/no information gap
A direct yes/no question has no question word identifying a missing place, time, or person: Komt Noor? Embed it with of: Ik weet niet of Noor komt. Here of means whether, not a choice between two named alternatives. The sentence leaves both coming and not coming open. By contrast, Ik weet dat Noor komt presents the arrival as known information. Choosing of versus dat changes the speaker’s commitment to the content.
Do not translate English conditional “if” mechanically as of in every use. Als Noor komt, maken we koffie makes coffee conditional on Noor’s arrival. Ik vraag of Noor komt asks whether that arrival will happen. The first sets a condition; the second identifies an information gap. Testing the meaning with “whether or not” can help distinguish the inquiry from a condition. It is a meaning check, not a demand to insert those words into every finished Dutch sentence.
Build the message
Turn Komt de docent? into a statement that you do not know the answer.
- Use ik weet niet for the uncertainty frame.
- The direct question has no information word, so introduce of.
- Put de docent before the finite komt.
Ik weet niet of de docent komt.
Retain the whole question phrase
When the direct question already begins with waar, wanneer, waarom, or another question word, keep that information word instead of replacing it with of. Wanneer begint de les? becomes Weet je wanneer de les begint? Asking whether a class begins and asking when it begins require different answers. A yes/no response to the outer “do you know” may be possible conversationally, but the requested information remains the starting time.
The question expression can contain several words. Hoe laat asks for a clock time, welke bus selects a bus, and met wie asks about a person in a with relationship. Keep the complete phrase together at the beginning of the embedded question: Ik weet niet met wie ze reist. Dropping met would change the relationship or leave the sentence incomplete. The noun in welke bus also retains its normal determiner agreement; embedding a question does not erase the grammar inside its opening phrase.
Move the finite verb without changing its subject
For a simple embedded question, put the subject before the late finite verb: waar de kinderen wonen. The subject remains plural, so wonen stays plural even though its position changes. The introductory frame may have a different subject, as in Ik weet niet waar de kinderen wonen. Do not make the embedded verb agree with ik merely because that subject appears at the beginning of the whole sentence.
A question word can itself be the subject. Wie komt er? and Ik weet niet wie er komt ask about the arriving person. In such cases, do not insert a redundant subject pronoun after wie. For ordinary person questions, identify whether the missing person acts or receives an action. Wie Noor belt can be ambiguous without context, so beginner practice benefits from fuller noun phrases or a clear situation. Natural ambiguity is a reason to clarify a message, not to pretend every short string has only one interpretation.
Handle separable verbs and multiple verbs
A separable verb that splits in a direct main clause reunites in a simple dependent clause. Wanneer komt de trein aan? becomes Weet je wanneer de trein aankomt? The time question stays at the front, while aankomt forms the end of the embedded predicate. Do not leave aan stranded in the direct question pattern. Treat the whole lexical verb as one unit when checking the dependent finite spelling.
With a modal or perfect, the embedded clause has a verb group: of ik kan komen or waar ze heeft gewerkt. Dutch also permits alternative orders in many two verb groups, such as waar ze gewerkt heeft. The important point is that the ordinary direct question order is not simply copied into the clause. Learn the model group appropriate to the sentence, and avoid treating every alternative final order as ungrammatical. The choices in this lesson test clear structural or meaning differences rather than disputed preferences.
Complete the reasoning
Ask formally for the train arrival time with aankomen.
- Start the outer request kunt u zeggen.
- Preserve wanneer as the requested time information.
- Build de trein aankomt, reuniting the separable verb.
Compare your reasoning
Kunt u zeggen wanneer de trein aankomt?
Use indirect questions to clarify practical details
An indirect frame can make a practical information request easier to place in a conversation: Kunt u zeggen of ik moet reserveren? It names exactly the uncertainty, here whether a reservation is required. A broad request such as “Can you explain everything?” gives the listener much less guidance. Select one missing detail: which document, whose name, what time, or whether payment is needed. A concise frame followed by a precise embedded question is usually more useful than several layers of politeness.
Negation inside the clause has its own scope. Ik weet niet of de deur open is negates knowing, not the door’s openness. Ik weet dat de deur niet open is says the speaker knows it is closed. These sentences can lead a listener to opposite practical conclusions. When reporting uncertainty, keep niet attached to the uncertainty frame and use of. When reporting a known negative fact, use an appropriate statement frame and put the negative inside its content. Read the entire message before deciding what is actually denied.
Choose finite or shortened how constructions deliberately
A useful full construction is Ik weet niet hoe ik dit formulier moet invullen. It explicitly names the actor and the requirement. A shorter construction is Ik weet niet hoe dit formulier in te vullen, with an understood actor and a te infinitive. In this pattern, the separable verb becomes in te vullen. The shorter version can sound more compressed or written; a full finite clause is often easier for a learner to construct and easier for a listener to follow.
Official advice also recognizes a Belgian standard hoe construction without te in suitable shortened questions. This is a specific regional pattern, not permission to delete te from every infinitive in Dutch. For production in this general course, use the full finite model when naming who should act matters. Then check the outer speech act, the information gap, the question phrase, and the embedded verb group. Those four decisions preserve both politeness and the exact detail the listener needs to answer.

Choose finite or shortened how constructions deliberately.
Ik vraag me af wanneer de bus vertrekt.
I wonder when the bus leaves.
The outer sentence reports wondering and takes a period in ordinary writing.
Weet u welke bus naar het centrum gaat?
Do you know which bus goes downtown?
The complete question phrase welke bus acts as embedded subject.
Kunt u zeggen met wie ik moet spreken?
Can you tell me whom I should speak with?
Met remains part of the requested relationship.
Ik weet waar Noor heeft gewerkt.
I know where Noor has worked.
Gewerkt heeft is another accepted two verb group order here.
Ik weet dat de deur niet open is.
I know that the door is not open.
The negative belongs to the known fact, unlike uncertainty expressed by weet niet of.
Notice the difference
Common mistakes
Keep whether open with of
Instead ofWeet je dat de winkel open is?
For this meaningWeet je of de winkel open is?
Dat presents the opening as stated content rather than whether it is true. Of leaves the yes/no information unresolved.
Preserve met in the question phrase
Instead ofIk weet niet wie ze reist.
For this meaningIk weet niet met wie ze reist.
Without met, wie cannot play the intended role in this sentence. Met retains the companion relationship.
Distinguish uncertainty from a known negative
Instead ofIk weet dat de deur niet open is.
For this meaningIk weet niet of de deur open is.
This claims knowledge that the door is not open. The speaker lacks information about openness.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
Ask someone politely whether the shop is open and what time it closes. Use two complete questions.
Compare with a model
Kunt u zeggen of de winkel open is? Weet u hoe laat de winkel sluit?
Can you tell me whether the shop is open? Do you know what time the shop closes?
The first question has a yes/no gap and therefore uses of. The second asks for a time and preserves hoe laat. Each outer clause is a question, so each gets a question mark. The embedded verbs is and sluit belong to de winkel, not to the formally addressed listener.
- Use of only for the yes/no gap.
- Retain the whole phrase hoe laat.
- Keep dependent order in both embedded clauses.
Your turn 2
Say that you do not know whether registration is required, then ask when the train arrives.
Compare with a model
Ik weet niet of ik me moet aanmelden. Weet je wanneer de trein aankomt?
I do not know whether I have to register. Do you know when the train arrives?
The first sentence is an uncertainty statement, with the first person reflexive me and a modal group. The second is a direct outer question containing a time question. The separable finite aankomt reunites, while aanmelden is a bare infinitive after moet. Each verb’s form follows its own construction.
- Do not confuse uncertainty with a known negative fact.
- Keep me with the first person registration action.
- Reunite aankomt inside the embedded question.
