Learn Hardcore Dutch: Ik moet overstappen op een andere trein.

moet is the 1st‐person singular present form of the modal verb moeten, meaning “to have to” or “must.” Here it expresses necessity: “I have to…”

Why is overstappen placed at the end of the sentence?

In Dutch main clauses with a modal verb, the finite verb (moet) occupies the second position and the main infinitive (overstappen) moves to the clause‐final position. Structurally it mirrors English “I must change,” but Dutch keeps the infinitive at the end:
• Ik (subject)
• moet (finite verb)
• overstappen (infinitive at the end)

What exactly does overstappen mean?

overstappen means “to transfer” or “to change” from one form of public transport to another. In this context it’s “to change trains.”

Is overstappen a separable verb, and if so, why isn’t it split here?

Yes, overstappen is a separable verb: in a simple present you could say “Ik stap over.” However, when you pair it with a modal infinitive (moet), you keep the separable verb together at the end:
• Correct: Ik moet overstappen
• Not split because the full infinitive stays intact after the modal.

Why do we use op in op een andere trein?

op is the required preposition in the fixed verb‐preposition combination overstappen op. It indicates the new vehicle you board: “to get on (op) another train.”

Could we use naar instead of op here?

No. naar expresses direction “towards” or “to a destination,” not “onto” a new vehicle. overstappen always takes op when naming the transport you switch to.

Why is it een andere trein and not de andere trein?

• een andere trein = “another train” (unspecified, any different train)
• de andere trein = “the other train” (a specific train already known in context)

Here the speaker hasn’t identified a specific train yet, so the indefinite een is used.

What gender is trein, and why doesn’t andere get extra ending?

trein is a common‐gender noun (it takes de in the definite form). With the indefinite article een, adjectives like andere don’t get an extra –e ending in singular:
• “een ander huis” (neuter noun)
• “een andere trein” (common noun)

Could you use a different verb like wisselen instead of overstappen?

In everyday Dutch for public transport, overstappen is the standard verb for “to change trains/buses/trams.” wisselen means “to exchange” or “swap” more generally and isn’t normally used for transfers in transport.
