This is the 357th most frequent Serbian word.
нову
The Serbian word "нову" means "new" in the accusative singular feminine form.
The word 'нову' is the feminine singular accusative form of the adjective 'нов' (new), agreeing with the feminine singular noun 'књигу' (book) in this direct object role.
Купио сам нову књигу.
I bought a new book.
Here, 'нову' functions similarly as a descriptive adjective in the accusative case, modifying the feminine singular noun 'идеју' (idea), aligning with the verb 'представити' (to present).
Морали смо представити нову идеју.
We had to present a new idea.
In this context, 'нову' modifies 'кућу' (house), which is a direct object in the sentence, and the declension matches its feminine singular form.
