Questions & Answers about Hij voegt het zout toe terwijl ik roer.
Where does the word toe come from in this sentence?
It is part of the separable verb toevoegen, which means to add. In a normal main clause, separable verbs split apart. The conjugated verb (voegt) takes the second position, and the prefix (toe) gets sent to the end of that clause, right before the conjunction terwijl.
The lesson says terwijl pushes the verb to the end. Why does ik roer just look like normal word order?
Because the clause is so short! The conjunction terwijl (while) forces the verb (roer) to the end of its clause. Since there are no objects or adverbs here, the end of the clause happens to be right after the subject (ik). If we added more words, you would see the verb jump to the end: terwijl ik de soep roer (while I stir the soup).
What would happen to the word order if we started the sentence with the terwijl clause?
The entire terwijl clause would count as the first piece of information in the overall sentence. This causes an inversion in the main clause, meaning the verb must come before the subject to keep the main verb in the second position: Terwijl ik roer, voegt hij het zout toe.
Why is the verb roer used here instead of roert?
