Learn Dutch: De kwantitatieve dataset moest gisteren worden bewerkt. - The quantitative dataset had to be processed yesterday.

The base verb werken means to work and is intransitive (it does not take a direct object). By adding the inseparable prefix be-, it becomes the transitive verb bewerken, which means to work on, to edit, or to process. This prefix allows bewerken to take a direct object—in this case, the dataset, which is then promoted to the subject in this passive sentence.

Why do we use worden bewerkt here instead of just werden bewerkt?

The sentence uses the past-tense modal verb moest. When a modal verb is used in the passive voice, the auxiliary verb for the passive voice must remain in its infinitive form, which is worden. Therefore, moest worden bewerkt translates structurally to had to become processed.

Could I swap the order of the verbs at the end and say bewerkt worden?

Yes! In a verbal cluster at the end of a Dutch sentence, the past participle (bewerkt) and the infinitive (worden) can appear in either order. Both worden bewerkt and bewerkt worden are grammatically correct and sound entirely natural.

Why does the adjective kwantitatieve end with an -e, and why is it spelled with a 'v'?
