Learn Dutch: Alles staat netjes klaar voor het feest. - Everything is nicely set up for the party.

In this lesson's context, netjes is an adverbial diminutive. By adding -jes to the adjective net (neat), it turns into an adverb meaning 'neatly' or 'nicely'. Using netjes sounds much more natural and conversational in Dutch than just using net when describing how something is arranged.

Why does the sentence use staat (stands) instead of is?

Dutch heavily prefers positional verbs over the verb zijn (to be). When items are arranged, set up, or prepared (like tables, decorations, or food for a party), Dutch speakers conceptualize them as 'standing ready' (klaarstaan). Using is klaar here would sound more like a person has finished a task.

Are staat and klaar working together as a separable verb?

Exactly. They form the separable verb klaarstaan, which means 'to be ready' or 'to be set up'. Because this is a main clause, the verb splits: the conjugated part (staat) takes the second position, and the prefix (klaar) gets pushed later in the sentence.

Since netjes ends in an 's', can it only be used as an adverb?
