Sentence structure - Zinsstructuur of woordvolgordeIntroductionSentence structure has to do with the order of >>constituents in a sentence. We can look at this in two ways: (a) the formal grammar of the sentence, its syntax, and (b) the information presented in the sentence, its pragmatics. Often these two aspects of sentence structure work together. We can distinguish between main clauses and subordinate clauses. The order of constituents in main clauses differs from that in subordinate clauses. The difference lies mainly in the position of the >>finite verb: it occurs towards the front in a main clause, but in a subordinate clause it occurs towards the back. Main clause: Subordinate clause: Wanneer begint de vakantie? De vakantie begint over twee dágen. Wat gebeurt er over twee dagen? Over twee dagen begint de vakántie..
