aan het + Infinitive
Progressive Aspect
The aan het + infinitive construction is the Dutch equivalent of the English '-ing' form (e.g., 'I am eating'). It highlights that an action is happening right now.
How It Works
In Dutch, the simple present tense is the default for both habitual actions and ongoing actions. However, when you want to specifically spotlight that someone is in the middle of an activity, you use the progressive aspect.
Key Rules:
- Word Order: Objects and adverbs are placed before 'aan het', and the infinitive usually ends the sentence. However, prepositional phrases (like in de tuin) can often follow the infinitive.
- Dynamic Verbs Only: Use this only for actions with duration (running, cooking, reading). Do not use it for states of mind like weten (to know) or for near-instantaneous actions like binnenkomen (to enter).
- Tense Flexibility: It can be used in the past by conjugating zijn in the imperfectum (e.g., Ik was aan het slapen) or in the future using zullen (e.g., Ik zal aan het werk zijn).
Examples (4)
- Wat ben je aan het doen?
What are you doing?
Word by Word: What are you at the do?
This is the most common way to ask someone what they are currently busy with.
- Ik ben een boek aan het lezen.
I am reading a book.
Word by Word: I am a book at the read.
Notice how the object 'een boek' comes before the 'aan het' construction.
- We waren aan het eten toen de telefoon ging.
We were eating when the phone rang.
Word by Word: We were at the eat when the phone went.
Using the past tense of 'zijn' creates the past progressive.
- Zij is de auto aan het wassen.
She is washing the car.
Word by Word: She is the car at the wash.
This emphasizes that she is currently in the middle of the task.
Common Mistakes
Using 'aan het' for a habit.
Different MeaningIk ben elke dag aan het werken.Ik werk elke dag.Ik ben elke dag aan het werken is good Dutch and stresses being busy with the activity. For a plain habit or fact, the simple present (Ik werk elke dag) is the neutral choice.
Placing the object after the infinitive.
Ik ben aan het eten een appel.Ik ben een appel aan het eten.The infinitive must remain at the end of the core verb cluster. Direct objects like 'een appel' must come before 'aan het'.
Using it with stative verbs like 'to know'.
Ik ben het aan het weten.Ik weet het.Verbs that describe a state rather than a physical action cannot use the 'aan het' construction.
How It Connects
Learn This First
To use the Dutch progressive aspect, you need to know how to conjugate the verb 'zijn' (to be) to match the subject. You also need to be familiar with the preposition 'aan' and the article 'het', which together with the infinitive form of the main verb create the 'am/is/are doing' meaning.

The progressive aspect 'aan het + infinitive' requires a conjugated form of the auxiliary verb 'zijn' (to be).
