Fixed verb + preposition: wachten op, denken aan

A number of Dutch verbs are welded to one particular preposition, and no substitute is allowed: Ik luister naar het nieuws (I listen to the news). Luisteren always takes naar, even though English pairs 'listen' with 'to'. Pairs like luisteren naar and wachten op (to wait for) are called fixed verb + preposition combinations — in Dutch, vaste voorzetsels.

No logic tells you which preposition a verb will demand, so do not try to reason it out from the meaning or from English. Store the preposition as part of the verb's dictionary entry: the moment you meet antwoorden, record it as antwoorden op (to answer); the moment you meet deelnemen, record it as deelnemen aan (to take part in). The two words behave as one item you look up and rehearse together.

1. Rehearse each verb with its preposition attached — deelnemen aan, luisteren naar — and never file the bare verb on its own.
2. The preposition holds steady across every tense: Ik luister naar het nieuws (present), Ik luisterde naar het nieuws (past), Ik heb naar het nieuws geluisterd (perfect).
3. Ignore what the English preposition would be. Deelnemen takes aan although English says 'take part in'; klagen takes over where English says 'complain about'.

The pairs below are among the most frequent — learn these first.

Adjectives can lock onto a preposition the same way. Bang (afraid) always takes voor — Ik ben bang voor honden (I am afraid of dogs) — and here zijn is only the linking verb. A few more worth learning as a unit: trots op (proud of), blij met (happy with) and tevreden over (satisfied with).

The verb's preposition also decides how you refer back to a thing. Dutch never places a preposition straight in front of het, dat or wat. When the object is a thing rather than a person, the preposition fuses with er — or with waar in a question or relative clause.

• Standing in for a thing with 'it': the preposition attaches to er, and the pair often splits around the words in between. Ik vertrouw op het systeem → Ik vertrouw erop. (I rely on it.) Ze denkt aan de reis → Ze denkt er vaak aan. (She often thinks about it.) More in er + a preposition.
• Asking about a thing: waar plus the same preposition. Waar wacht je op? (What are you waiting for?) Waar klaagt hij over? (What is he complaining about?)
• In a relative clause about a thing: de trein waarop we wachten (the train we are waiting for). See waarmee, waarover.

For a person you keep the plain preposition plus a pronoun: Ik wacht op hem (I wait for him), never ik wacht erop.

The commonest slip is reaching for the English preposition. 'Take part in' tempts you into deelnemen in, but the fixed pair is deelnemen aan; 'complain about' tempts you into klagen van, but Dutch uses klagen over. The second pitfall is denken, whose meaning shifts with the preposition. Denken aan is to hold someone or something in your thoughts (Ik denk aan mijn oma, I think of my grandmother), while nadenken over is to reflect on a question or reason through a choice (Ik denk na over het aanbod, I am mulling over the offer). Because the preposition carries part of the meaning, always store it with the verb — the core prepositions page lists what a preposition means on its own, not which verb selects it.
