Questions & Answers about Je moet letten op het gedrag van het kind.
This lesson is about using er + preposition. Why is there no erop in this sentence?
Because the object here is a regular noun phrase (het gedrag van het kind). You use an anticipatory word like erop when you are pointing forward to a full action or clause. For example, if you wanted to use a dat-clause, you would say: Je moet erop letten dat het kind goed slaapt (You must pay attention to the fact that the child sleeps well).
If I want to replace 'the behavior of the child' with 'it', how would I say 'You must pay attention to it'?
You would use erop! In Dutch, you cannot say op het when referring to an inanimate object or concept. Instead, you use er + preposition. The sentence would simply become: Je moet erop letten.
Is letten op a fixed expression?
Yes, the verb letten (to pay attention / to watch out) is almost always paired with the preposition op. While in English you pay attention to something, in Dutch you pay attention on (op) it.
Why is the infinitive verb letten in the middle of the sentence instead of at the end?
