Questions & Answers about We zouden die betweter niet moeten geloven.
Where exactly does the word betweter come from?
It is a combination of beter (better) and weten (to know), literally describing a "better-knower". It is the perfect, everyday Dutch translation for a "know-it-all".
Why do we need both zouden and moeten here just to say "shouldn't"?
In Dutch, the concept of "should" is expressed using the conditional form of moeten (must). By combining zouden (would) with moeten, you literally say "would must", which is the standard way to express "should".
Why is niet placed after die betweter instead of before it?
Because die betweter is a specific direct object, indicated by the demonstrative word die (that). In Dutch, niet generally comes after a specific direct object, pushing the negation right up against the verbs at the end of the clause.
At the end of the sentence, could I swap the verbs and say geloven moeten?
No, standard Dutch requires the modal verb (moeten) to come before the main infinitive (geloven) in this kind of verb cluster. While you sometimes have a choice with auxiliary verbs like hebben or zijn, modal verbs almost always come first in the cluster.
