Questions & Answers about We moeten de kamer netjes opruimen.
How does the word netjes demonstrate the grammar for this lesson?
The word netjes is formed by taking the adjective net (neat or tidy) and adding the diminutive suffix -jes. While diminutives are usually for nouns, adding -jes to an adjective creates an adverb of manner. In this sentence, it tells us how to tidy the room: neatly.
Could I just use the base adjective and say We moeten de kamer net opruimen?
It is highly recommended to use netjes here. If you use net, it can easily be confused with the adverbial meaning of just or just now (as in we just cleaned the room). Using the -jes form avoids ambiguity and ensures the meaning is neatly or properly.
Why isn't the separable verb opruimen split up in this sentence?
This is due to the modal verb moeten. When a modal verb takes the second position in a Dutch main clause, the main verb (opruimen) is pushed to the very end of the sentence as a full, unbroken infinitive.
Does netjes only work as an adverb of manner?
Originally yes, but it has become so integrated into Dutch that native speakers now frequently use it as a regular adjective too, such as in een netjes huis (a tidy house). In this sentence, however, it modifies the verb opruimen and functions purely as an adverb.
