nieuw
"Nieuw" means "new" in English.
Here, 'nieuw' describes an adjective used to indicate that the book is new, not previously owned or used.
Ik heb een nieuw boek gekocht.
I bought a new book.
In this case, 'nieuw' is inflected as 'nieuwe' because it precedes a definite article, describing the restaurant as recently opened.
Heb je het nieuwe restaurant in de stad geprobeerd?
Have you tried the new restaurant in the city?
Here, 'nieuw' represents something recently developed or emerging, highlighting innovation or novelty.
