Sequencing events in the past
In Dutch, when using the conjunction nadat (after), you must explicitly show the sequence of events by using a "completed" (perfect) tense in the subordinate clause.
If the main action is in the Simple Past, the earlier action in the nadat clause must be in the Past Perfect (had/hadden + past participle).
| After we had found the gas station, we refueled the car. | Nadat we het tankstation hadden gevonden, tankten we de auto bij. |
Because nadat introduces a subordinate clause, its verbs move to the end. When a sentence starts with the nadat clause, it triggers inversion in the main clause (e.g., tankten we).
| After they had booked the accommodation, they began the hike. | Nadat ze de accommodatie hadden geboekt, begonnen ze aan de wandeltocht. |
Sequencing events in the present
This tense alignment also applies to present actions. If the main clause uses the Simple Present, the earlier action in the nadat clause must use the Present Perfect (hebben/zijn + past participle).
| We navigate to the next city, after we have eaten at the gas station. | We navigeren naar de volgende stad, nadat we bij het tankstation hebben gegeten. |
| After we have paid the toll, we refuel so that we can drive on. | Nadat we de tol hebben betaald, tanken we bij zodat we verder kunnen rijden. |
Separable verbs and "nadat"
Many travel-related verbs in this lesson are separable (e.g., opwarmen, bijstellen). Their past participles place -ge- between the prefix and the verb stem (opgewarmd, bijgesteld).
| After he had warmed up the soup, he settled down on the couch. | Nadat hij de soep had opgewarmd, streek hij neer op de bank. |
| He turns the car around, after he has adjusted the route. | Hij keert de auto om, nadat hij de route heeft bijgesteld. |
Verbs indicating a distinct change of state or direction—like omkeren (to turn around)—take zijn instead of hebben in their perfect tenses.
| After we had turned around, we adjusted our plan. | Nadat we waren omgekeerd, stelden we ons plan bij. |
